Imagine you have a pair of subwoofers in your home theater or car, you might know how hard it is to set the bass levels the right way. This means how to set the crossover frequency at which the subwoofer begins playing these bass notes.
Before getting to helpful tips on how to earn the best bass performance possible, let’s learn more about the basic function of crossover. But first, it’s very important that you have a deep insight into the answer to the question “what is crossover frequency?”
The crossover frequency of a subwoofer is the frequency kickstart rolling off, and that woofer will start with low-frequency effects and bass notes. But when it comes to its basic function, it could be active or passive, digital or analog.
Apart from splitting the audio spectrum into 2, 3 or more bands, the audio crossover is known to be used on loudspeakers units adapted for such frequencies. Besides, they are always intended for any work with one specific loudspeaker design.

However, for sound increase apps, these frequencies can be changed by the front panel controls. Here are some functions that are applicable to active and passive crossovers:
As we see, the demand for any certain crossover comes from the impracticability of creating one drive unit that can deal with the 10-octave spectrum well. Besides, removing a passive crossover here means the increase in power efficiency and the decrease in cost.
Every AV receiver would feature one auto EQ (Equalization) that can set the right crossover frequency automatically, depending on the loudspeakers’ capabilities. In other words, it would be best to leave such settings where they’re supposed to be.
In case you’re availing one AV processor for crossover frequency adjustment in surround sound, we’d like to share you a few tips on how to achieve the best performance as possible.
We both know that the reproduction of the music’s LF, which is seen as the biggest difficulty that can face the audiophile. To receive the extended and clearer bottom end in the listening rooms, it’s quite challenging due to the physics laws. As a result, many of us tend to live with less than the great bass performance.
And a wonderful bass performance here is largely rewarding with the bottom end creating the tonal base of some kinds of music. But how to improve the bottom end of the existing audio system? Let’s discover several options if you just begin upgrading and don’t miss considering some principles for earning the best bass.
Just start with a few basics of bass reproduction at first. How about placing a music system based on little speakers that can’t remake the bass under 50Hz? It’s completely true for some listeners who prefer to lean over the tinier-scale works in pop, classical, and acoustic music.
And those listeners with these inclinations should go with the tinier speakers that have the restricted bass response than the full-range ones sold at a similar price. Aside from this element, the quality of bass performance is just another important thing to consider than its quantity.
Listeners with musical tastes should go with smaller speakers than the full-range ones
If the bass can’t be reproduced well, then you should not hear it since the poor bass only turns out to be a big annoyance. One of the most important things to consider here is the high cost of the precise bass reproduction. The lower the frequency is precisely reproduced, the costlier the bass becomes.
Please note that the word “precise.” For example, you can purchase a loudspeaker at $500 that owns the output under 40Hz, but it’s impossible for the bass to produce precisely. And the bigger the cabinet, the more prone it is to the vibration that can color the sound. Your music will be tonally colored, not to mention how its dynamic structure is destroyed.
So the best solution to fix it here is to set up the enclosures that can’t vibrate, but they’re mostly heavy and costly.
Just spare some more time tweaking the controls of a subwoofer to make it blend perfectly with your speakers. Don’t mind taking advantage of its volume, crossover frequency, and other adjustments to ideally dial into the system. Remember that the lower the crossover frequency between your subwoofer and main speakers, the better.
You can add subwoofers to your system to extend the bass
For the bass of your loudspeaker, it’s sure of the better quality than that of a subwoofer. Having the low crossover frequency means that you can’t locate the sounding source of that low bass. In other words, choosing a subwoofer that can reproduce the frequencies over 100Hz will allow the localization.
Last but not least, the phase of one subwoofer enables the listener to align its wavefront with that of the loudspeakers. You can try to drive your system with one pure tone at the crossover frequency. This makes both subwoofer and loudspeakers reproduce the similar signal.
Bass management or improvement has been seen to be thrown a lot around the online forums. Follow our guide today, and you will learn the fact “what is crossover frequency?” and how to use the customized crossover settings as an active subwoofer is available in your system.
