In addition -- see below -- you will *STILL* need a separate Subwoofer for proper handling of Low Frequency Effects (LFE) Bass! The idea, of course, is to pick the Crossover Frequency -- from within your range of candidate frequencies -- which produces the smoothest tone sweep (the least variation in Volume). So their different locations are not a problem, and can, in fact, produce other benefits! Those new frequency bands are then sent to different loudspeaker drive units that are created specifically for those frequencies. If you think about it, the physics of a given speaker cone generating Standing Waves in the room is largely a matter of geometry. We recommend settings to a higher frequency than the crossover frequency when small speakers are used. Where they are exactly opposite of matching up you get "Cancellation Nulls" -- a loss of level of that Bass frequency. As a rule of thumb, the lower the subwoofer’s crossover is set, the better. I just upgraded to a bigger subwoofer, a JBL ES250P rated at 400 watts RMS and 700 watts peak power. Visit my About page to read about who I am and what I do. The low‑pass filter only allows signals below a certain frequency (for example, below 2kHz) through to drive the mid‑range driver/woofer of a two‑way speaker system. I guess experimentation is in order to determine if dialog is improved by adjusting the center channel speaker equalizer settings in the 1-4 kHz range; AND, then playing with the crossover frequency of the center channel speaker to see if increasing the crossover to, say, 120 Hz helps the dialog clarity. A crossover unit enables you to get a great sound because you are giving the right frequencies to the right speakers so they can do the best job of creating the sound. If you have got a cheap speaker, which does not sound pretty well or fascinating, at least to you, then modifying your crossovers could help your car audio system sound better. Sending a full-range signal to all speakers within the system, regardless of each speaker’s design, can be problematic. In my experience, it's best to set the low crossover point below the vocal frequency range and set the high crossover point no lower than 2.5kHz. And we know we have to compare those candidates against what our gear can actually handle. The Subwoofer then receives the COMBO of all this Steered Bass -- i.e., from all the speakers -- in addition to the special Bass found in the LFE channel. And at these Bass frequencies, even INCHES make a significant difference in how a Bass speaker couples to the room! There are slight differences with the features of each unit, so my recommendation is to look for durability and extra features of these to help make your purchase. Wavelength also works as you move away from the baffle so if the crossover frequency is set at 3000Hz and the drivers are placed further apart you will get lobeing if the midrange and tweeter drivers are more than 4.5 inches apart. This means at no additional cost to you, I get paid if you click through and make a purchase). Making changes and measuring with an active crossover or digital crossover is easy and painless. This is a special channel reserved for carrying LOUD Bass -- definitely the sort of stuff you'd want to send to your Subwoofer! These Subwoofers may be either Dynamic or Musical in design. This test tone goes to just the Front speakers. High-Pass Crossover is the frequency above the low-pass crossover where your speakers will start working and take over from a subwoofer. Its actual frequency response is 25hz to 150hz. I have 5 speakers with a frequency response from 120hz-23,000hz. The usual workaround is to set a lower, compromise Crossover -- one that asks the regular speakers to go a little lower than they can handle, but also gets closer to the high frequency limit of the Subwoofer. It gives me the option between 80hz, 90hz, 100hz and 150hz. First, they want their Subwoofers to be LOUD. The Subwoofer should ALSO be handling the lowest frequencies of this audio, as well, so that your regular speakers are not challenged with trying to reproduce it! A common, pseudo-technical description of Bass audio constrained inside a room like this is that the Bass audio "pressurizes" the entire volume of the listening room. And THIS is where we start to run into the REAL complications of Bass Management! Why? Many car audio stereo receivers on the market feature an integrated and user-adjustable crossover system, designed to route certain sound frequency ranges to specific speakers connected directly to the head unit, or through low-level outputs designated for external audio … -- experienced 60 Hz, power line interference hum, at one time or another. The folks who make Subwoofers will target these demands by marketing different models as Dynamic or Musical! This goes back to the concept of Bass frequencies "pressurizing" the entire volume of space in the listening room. What speaker crossover frequency are you using for your home theater? Here is my dilemma. Suffice it to say filtering which works like a switch -- a so-called "Brick Wall" filter -- will do damage to the audio. And raising or lowering the Crossover Frequency changes how MUCH Bass is coming out of the Subwoofer vs. the regular speakers across those shared frequencies. I am connected with an LFE cable, so I need to set the response on my receiver. My question is: Should I stick with the subwoofer's listed crossover frequency of 80 Hz when running sound for a rock band at a small outdoor venue? As with many such complicated things, there's always a place to begin! You'll see, by the way, that the 80 Hz Crossover Frequency I described as "typical" towards the top of this discussion is right about in the middle of the likely range. A good starting place is with the high-pass filters on the front and rear channels set at 100 Hz, and the subwoofer channel's low-pass filter also set at 100 Hz. If they are smaller, bookshelf style speakers there is of course no comparison. The concept of the subwoofer is based on the falsehood that you cannot directionalise bass below 80 Hz (some say 200 Hz). The Bass comes "from everywhere" instead of from the location of any speaker. There are some things to consider regarding the shape of the room and how the speakers will interact with boundaries, such as the walls, the ceiling, and the floor.You want to get the best speakers your budget will allow. So you set your Crossover at 60 Hz. These Crossovers and PA Management devices are the most popular on the market currently. Most mid-priced full-range loudspeaker cabinets have a passive crossover built into them (and some amplifiers, including our own d&b audiotechnik D12s, also incorporate crossover functions). That is, how its physical location in the room amplifies or attenuates various Standing Waves. If you do not need mids as you only have high and low speakers, each unit will still work for your rig by not using the mid outputs. Need anything? And even for speakers that DO plug in, unless they have large Bass driver elements (cones) and dedicated amplification for those, they are not going to hold their own against a decent Subwoofer. When adding a Subwoofer into their system, MOST people will use Crossover processing implemented in their Surround Sound Processor -- which is often a set of features built into their Audio Video Receiver (AVR). In other words, Crossovers allow you to connect subwoofers to your live sound rig. Positioning the speaker closer to a wall enhances reflections off that wall. An octave is simply common parlance for a factor of 2 in frequency. Again, setting the sub's crossover control to the 80-Hz position is a good place to start. Many car audio stereo receivers on the market feature an integrated and user-adjustable crossover system, designed to route certain sound frequency ranges to specific speakers connected directly to the head unit, or through low-level outputs designated for external audio amplifiers. I am not really sure whether I … So, if you DO have a range of Crossover Frequency candidates (after thinking through the upper and lower limit considerations described above), one of the best ways to choose between them is to pick the Crossover Frequency which MINIMIZES the inherent, Bass Room Response issues in your listening room! C-A also plays a role in sound exposure and noise pollution applications. So now we have a range of possible Crossover Frequency candidates. And the challenge of Bass Management lies in taming these problematic, Bass Room Response issues. Mixing live sound is one of the most fun yet challenging aspects of music, and the ability to mix both in the studio and live makes a good audio engineer in high demand. So we know what THAT sounds like. And those different Standing Waves *INTERACT*! And so even ONE Subwoofer can handle the Bass from ALL the regular speakers without confusing the audio imaging. Why? For the mid/woofer crossover there are 4 octaves between 200-3.2k Hz, 200-400-800-1600-3200. I.e., they couple to the room differently and produce different Standing Waves. If there's any male dialog in those speaker channels, a 160 Hz Crossover will steer it to the Subwoofer. AND the audio from the Subwoofer will start to be localizable! Where the different Standing Waves happen to match up you get "Resonance Peaks" -- a boost in level of that Bass frequency. An adjustable crossover frequency can be a real bonus for tuning your rig. When using multiple amplifiers or a multi-channel amplifier, you're going to want to choose a crossover point. Sound system distortion between these points can easily be heard and therefore the worst position to cross speakers over, but we have no choice. But even if you have larger, "full range" speakers -- speakers with specifications saying they are good down to 30 Hz, or even lower -- you are not going to get the same quality of Bass out of them as from a well selected Subwoofer. That being said, make sure that you have the outputs you need for your speakers. Welcome to Sound Certified! ... Plug the main outputs of your console into the GEQ, then into the inputs of the crossover. So the LOWER limit for the Crossover Frequency would be TWICE the bottom end of your regular speakers. A loudspeaker system without a properly designed crossover (or none at all) can cause too much frequency overlap between drivers which can increase distortion and degrade overall sound quality. Again, it is NOT an issue with the audio output quality of any of the speakers, or the Subwoofer. The impact will vary both by Bass frequency and listening position. At the high frequency end of that sweep, the audio will come entirely from those speakers. If you’re getting a powered subwoofer, then it will probably come equipped with an active built-in crossover, but you’ll want to check to be sure. Let's take a look at the basics of mixing live sound , and how you can be quickly on your way to learning to mix. Because the Subwoofer can be physically damaged if it is forced to reproduce frequencies below what it can handle -- typically due to the cone being asked to travel too far, called "bottoming out". Subwoofer designs are optimized for Bass, and that means they are not going to do a good job handling higher frequencies of audio. Home Theater Subwoofers have cone diameters in the range roughly 10-18 inches, and, equally important, they have power amps built in, dedicated solely to moving that big cone. The more expensive (and usually larger) Subwoofers can extend that low end down to, say 15Hz. Now think about that for a moment. The Rockville RPG15 offers a great sound quality in its simply amazing output. For example, set to "250Hz" when the frequency range of the speakers is 250Hz - 20Hz. And that means you need both size AND power in the speaker doing the huffing! But in addition, all the REGULAR speaker channels can also carry Bass -- with no limit on how low their frequencies can go. Recent design trends are for power to be decreased to -6dB (1/4) to each speaker at the crossover point. Crossovers take a signal from your mixer that is a left and right channel, and separates them so you can separate signals to different speakers based upon frequencies. Your choice of speakers should be based on coverage requirements and the size of the venue. The lower the frequency, the longer the wavelength. Indeed some of those speakers are likely on the opposite side of the room! The audio going to the regular speaker drops even more below 40 Hz, but by the time you are -12dB down, you can pretty much ignore the audio coming out of the regular speaker. Choosing the most appropriate crossover frequency is complicated by the fact that the point to choose depends on the crossover that is built into the sub. Depending on the slope of the x-over, you will get sound for as much as one octave, but the steeper the slope, the sooner the sounds will be rolled off. Welcome to Sound Certified! They want their steered Bass to be handled just as well as their regular speakers handle the higher frequencies. they may be rated only down to 80 Hz. →. Instead, you are simply specifying whether or not you want Crossover processing to happen. OK, if you've followed me so far, you should now be convinced you need at least one Subwoofer in your Home Theater setup (maybe MORE than one) -- budget and physical space allowing, of course. "Steering" bass from the regular speaker channels to the Subwoofer is the job of "Crossover" processing. And thus the Bass frequencies they share in producing across that Crossover octave -- from your chosen Crossover Frequency down to 1/2 that frequency -- couple to the room DIFFERENTLY from each of them. I just upgraded to a bigger subwoofer, a JBL ES250P rated at 400 watts RMS and 700 watts peak power. The result is what's called a "Hole" in the Crossover. MARKETING NOTE:  Subwoofer buyers typically have two conflicting demands. There's no set definition of what constitutes Bass frequencies, but for purpose of discussion lets focus on frequencies below 150 Hz. The optimal range is 20-20,000Hz – this is generally accepted as being the range of human hearing. Much of the visceral excitement of Home Theater -- whether for movies or music -- comes from the proper rendering of Bass frequencies. Speakers that can handle the full optimal range are referred to as "full range". If I am understanding this correctly, it is a borderline choice between 80 or 100. Should I set the subwoofer crossover at or near 60 Hz? But there's ALSO the issue of how that speaker "couples" to the room. What about the lower limit? That thud you feel in your gut from a really deep effects sound, or perhaps from the lowest pedal notes of a pipe organ, are found down here! A Weighted SPL is generally a good indicator for noise-induced hearing loss, although extremely high levels of low frequency energy can be damaging, so if a mix has a high C-A value, that is a good indicator that additional attention should be paid to LF exposure. Firstly, on most ecommerce websites, they mention another option called PA management. So suppose you think through all this and discover you actually DO have a range of candidates to choose between? That might not sound like much of a difference below 30Hz, but it REALLY IS a big deal! So if you have a Crossover which begins at 80 Hz, and takes effect at a rate of -12dB per octave, that means the audio going to the regular speaker will be reduced four-fold by the time you get down to 40 Hz. For a 50 Hz wave, 1,130/50 = 22.6 ft.) ... AIR15s, and AIR18s, are equipped with a variable lowpass filter, allowing you to dial in the best crossover point for your system. The result isn't satisfactory because of the reported suckout around 80/90 Hz. A Small speaker will be processed for Crossover. Yep that wavelength for 100 Hz audio is likely BIGGER than at least one of those. Subwoofers also differ in how LOW they can go in frequency. Both the low pass filter and the high pass filter have a cutoff frequency of 80 Hz. The reason is that something called phase distortion generates around each filter's crossover frequency, muddying up the sound. (Which also means they need to be plugged in to wall power.). While the type of crossover varies from model to model, one of the most common and best-performing is the 2nd order crossover with a slope of -12dB per octave. However, folks who have invested good money in regular speakers, don't want the low end of those speaker channels compromised by inaccurate Bass reproduction! Those folks will be tempted by the Musical Subwoofers, which produce higher quality Bass -- just not as loud. Instead, I want to focus on the contribution a good choice of Crossover Frequency can make in this effort! That is to say, at 80 Hz and above, the regular speaker is carrying the audio. And by the time you get down to 50 Hz audio (see that table), the wavelength is likely bigger than ALL THREE dimensions of your room. Both of these types of hardware do some of the same things, but have a few minor differences. The most flexible subwoofer crossovers currently available are those done in the digital domain, but even with a digital crossover there can be some phase shift (but far less than an analog circuit) in the main loudspeakers near their low-frequency attenuation point that can create some discontinuity between the time domain of the main loudspeakers and the subwoofers. The Rockville RPG15 offers a great sound quality in its simply amazing output. All Rights Reserved. 100 Hz sounds … To better visualize this, look at this graph. A 3-way crossover design adds a band-pass filter that selects midrange frequencies for the … When I listen to music, they sound pretty similar. But again, expect to have to go up in size (and price!) They simply can't move enough air to have a chance of handling Bass properly. As a general guideline, the crossover frequency should be set 10-15 Hz higher than the rated low frequency extension for each individual speaker, typically listed in the specifications. But Second, they want their Subwoofers to be ACCURATE -- to produce Bass of high quality. Well what happens is that the natural reflections of the audio set up what are called "Standing Waves" of sound for each frequency. Positioning it closer to a corner does this even more so. PA Management does the same thing as a crossover, but it has additional features which is why it "manages your PA."  These features will vary depending on the hardware you get, but it can include feedback reduction, limiters, and EQ in addition to being a crossover. And that might be only, say, 120 Hz! There ARE other ways of implementing Crossover, but we'll focus on this typical way. The numbers below highlight general guidelines for speaker/subwoofer crossover frequencies TECHNICAL NOTE:  You will likely encounter setup menus in your AVR or Surround Sound Processor asking you to specify whether your speakers are Large or Small. You can set a crossover for the other speakers (C and Surr). If you use a crossover frequency much higher than 80 Hz, deep bass will start to be directional, so you risk hearing the subwoofer as a "source" of sound, which is what you want to avoid. A typical Crossover implementation will roll into effect at a rate of, "-12dB per octave". Frequency response measurement of main speakers taken with XTZ Room Analyzer II Standard – the 25Hz and 50Hz points on the rolloff slope have been annotated. That says the Crossover should be no lower than 160 Hz! Copyright 2018 BlackSkye Media LLC. Now you can fine tune the signal being sent to each speaker by sweeping the crossover points until you find the perfect sonic fit. Subwoofers are, of course, specialty speakers designed with just this in mind. That means that one full octave is not necessary in all cases, but you need to account for about 2/3 or so of that frequency range below the x … A good Rule of Thumb is you don't want your Crossover to be higher than 100 Hz. Why? A typical Crossover Frequency would be 80 Hz. If everything is working RIGHT that sweep tone will appear to have constant Volume from end to end across the frequencies (except for the very lowest Bass frequencies which will drop off because they can not be heard). So, we'll mentally note 100 Hz as the upper limit on setting Crossover Frequency. You can get two (or more) of a smaller model and position them around your room to work as a set. If these are the speakers you have to work with, then, of course, this is a problem you will have to live with. The telephone system operates between these 2 points. All three KS Series Active Subwoofers feature powerful DSP, which allow you to adjust a number of useful parameters. We can be contacted through our contact us page found here. Setting a crossover point in the middle of the vocal range can mess up the vocal sound, especially if you use radically different compression settings on each side of the crossover frequency. I’m here to provide informative articles, product reviews, and buying guides to help you. But there's an alternative. So the LOWER limit for the Crossover Frequency would be TWICE the bottom end of your regular speakers. Bass Control computes the best possible results for the crossover frequency that is assigned by default but the user has to choose it... so that some experimentation is possible and in some cases necessary. However, there are common frequency ranges that will work well in many cases. TECHNICAL NOTE:  There's preliminary setup you need to do prior to trying this test, of course. And with Bass audio, that means understanding why you need to include a Subwoofer in your speaker configuration, and learning how to select a Crossover Frequency to drive it. Picture in your mind the dimensions of your Home Theater viewing room:  Front to Back, Side to Side, and Floor to Ceiling. My choice in crossover for my receiver is 80, 100, or 120. In other words, Crossovers allow you to connect subwoofers to your live sound rig. 2-way speakers use 2 speakers on each channel and a crossover to divide the audio frequencies reproduced between the two. I.e., one of those less expensive Home Theater "Dynamic" Subwoofers I described above? Some speaker makers also sell "satellite" Subwoofers, which are separate units intended to be attached to a single speaker, each -- and thus functioning AS IF a Subwoofer was built into each such single speaker. If you try to push things too far -- say setting the Crossover at 50Hz in this example, trying to take a little more advantage of the "down to 30 Hz" goodness of your regular speakers -- you may bypass the low-end protection in the Crossover and send 25 Hz audio (or even lower) to that Subwoofer! "Fire Maidens of Outer Space" (1956) on Blu-ray -- The Point 'N Laugh Experience! Now this is the point where the speakers are going to pick up where the sub left off. But what's more, it's also possible your Subwoofer is not even CAPABLE of reproducing frequencies as high as 160 Hz! For subwoofers: the recommended crossover frequency is 80 Hz (low pass). The result isn't satisfactory because of the reported suckout around 80/90 Hz. Here's a link to a handy table from JdB Sound Acoustics listing the Sound Wave Lengths for various frequencies of interest -- along with the frequency ranges of voices, pianos, organs, and guitars for comparison. The sub specs say it can play down to 25 Hz, which is very low, and the sub has a crossover adjustment that goes from 50 Hz to 150 Hz. The ".1" in "5.1" or "7.1" tracks, for example. It's just that the frequencies BELOW 30 Hz are more "felt" than "heard". To make the most of this upgrade though, your crossover should have a dedicated low frequency summing output to provide a mono signal to your sub. This includes almost all of the lowest Bass notes from musical instruments. Crossover points and Order. So you'll have a Subwoofer built into each such speaker, plus another, stand alone Subwoofer for LFE.). In that case the Crossover range itself (60 to 30 Hz) is handled, but the Subwoofer can not go below that. This is a TOUGH test, and you are unlikely to get a perfect result without going into more effort in configuring your Bass Management and dealing with Room Response issues. Console Main Outputs > Graphic EQs > Crossover. Using a crossover allows control over which frequencies are sent to which speakers, so that all speakers in the system work together to achieve the best possible sound quality. Or, of course, you could upgrade to better speakers! Typically, a low-pass crossover is anywhere from 40Hz and could go up to 60Hz to 100Hz. The PROBLEM derives from those Bass audio Standing Waves I described up top. Limited range speakers are far more common than full range units. Your Subwoofer may be very good, but it probably won't be AS good as your regular speakers in rendering something so precise as human speech! This will ensure a smooth frequency response when the drivers are combined. The freq response on the sub is 35 Hz - 120 Hz, with a crossover of 80 Hz, while the freq response on the mains is 58 Hz - 17 KHz, with a crossover … This audio doesn't vanish, of course:  THAT'S the audio that's getting steered to the Subwoofer! Some subwoofers also … And you'll recall from that table linked above, this is a "safe" frequency for Bass steering, since the wavelengths of audio 80 Hz and lower are going to be long enough to trigger that "pressurizing" effect -- i.e.,to be "non-localizable". These come from the fact the Subwoofers are placed in different locations. The Bass we'll be most concerned with in this discussion is the range below 100 Hz. Keep in mind, this has to be done for EACH speaker channel. In a passive speaker, the electronic crossover components determine where the sound transitions from the speaker channels to a subwoofer. We've already talked about ONE problem with that. Unfortunately, setting things up to ACHIEVE awesome Bass is complicated -- almost to the point of being a Black Art! Ideally, the crossover point will be the point when the two filters that make up the crossover intersect at -3dB. This rather unfortunate nomenclature has become pretty much industry-standard. This is the "pressurization" of the room I've alluded to several times  And the different dimensions of the room --its height, width, and depth -- result in DIFFERENT Standing Waves. The differences between studio engineering and live sound are like the differences between porn and sex. Indeed, Crossover processing systems (and better Subwoofer designs) include protection to keep from sending TOO LOW frequency audio to the Subwoofer. So plan accordingly. If you do, then the content below the crossover frequency you set will be sent to the front L and R. But, if all 5 of your speakers are identical then there is no benefit in doing that. If they are rated down to 50 Hz, the Crossover Frequency should be no lower than 100 Hz. And most of us have -- alas! If you find yourself still wondering what the best audio crossover is or have any other recording questions at all, we are always there to help! Among other things, this keeps them from hopping around as that cone moves! The best crossover frequencies for this setup will be: Sub: Set the low-pass filter to 80 Hz (with a slope of 12/24 dB) Rear coaxial drivers: Set the high-pass filter to 80 Hz (with a slope of 12/24 dB) You might wonder how this can possibly work, since the Subwoofer -- or even multiple Subwoofers -- are not sitting in the exact same position(s) as any of the speakers. Crossovers are devices that split your signal in two — low frequencies go to the subs and everything else goes to the mains. If they are rated down to 30 Hz, the Crossover Frequency should be no lower than 60 Hz. The range of frequencies a speaker will reproduce (lowest to highest) is in many cases limited. The problem is, they may be able to produce sound down that low, but they won't be able to do so AT VOLUME! The crossover frequency is where the low-pass filter starts to fade, and the high-pass filter starts to increase the amplitude of the signal. Crossover settings are device specific as others have said but I will add not just in regard to corner frequency but also in terms of the filter type and slope/order. 12dB, you'll recall from my discussion of Balancing Speaker Volume Trims with an SPL Meter is about a factor of 4 in perceived volume. In my experience, it's best to set the low crossover point below the vocal frequency range and set the high crossover point no lower than 2.5kHz. The bulk of the energy in "big" movie sound effects -- things like explosions -- comes in around 50 Hz. This a good low-pass frequency that ensures the subwoofer bass is prioritized without including any midrange sounds. I'll have more to say about Bass Management and Room Response in future posts, but as I said up top:  The road to awesome Bass begins here! Meaning you may have to step up to a larger, more expensive model to handle the size of your listening room. Such Subwoofers may be perfectly adequate for folks looking mostly to handle Bass effects in action movies -- explosions and such. But what if your Subwoofer is ALSO rated down to only 30 Hz? Visit my About page to read about who I am and what I do. I picked up a Behringer (I know) crossover which has a number of different controls on it. Now, to perfectly match your KS active subwoofer with your top active loudspeakers, you need to choose a suitable crossover frequency (80 or 100 Hz) – and apply the correct setting to both subwoofer and top … Come entirely from those speakers are rated down to TWICE the low frequency it.
