[QUOTE="DidUHearThat?, post: 5778317, member: 594758"] 27 hz is where your box is designed to peak. Basically the lowest point it will play. It's output drops quickly below 27 hz. Your crossover point is a compeltly unrelated matter. It represents the HIGHEST frequency that is being set to your amp. By setting it at 32 hz, your sub is only playing from about 27 hz to about 32 hz .That's a band width of about 5 hz. So yeah, it sounds like one a one note sub, because it is. That's very narrow. Raising the crossover point allows the "higher" sub frequencies to get to the amp, then to the sub. The sub sonic filter sets the lowest frequency that can get to your amp, then to the sub. It should be about 20 hz. Raising the crossover point to 60 hz will allow your sub to play from around 60 hz down to below 27 hz. (the slopes are not sudden, but actuall fall off over several frequencies. 27 hz and 60 hz is where the slope start your actual bandwidth will probably be around 20 hz - 70 hz). [/QUOTE]
