So here is a really stupid question, and I didnt find anything in the few searches I tried... Why is the low end of the frequency response of bass cabs so high? I understand that its different from a subwoofer in that its a full range speaker/different responses are expected, but why is it that so many people worry about a cabinet going low enough for a low B? I have an 8 inch sub woofer for my stereo that is about 1/3 the size of my ampeg B-100R, yet it hits about 10 Hz lower. SO the question is, if you're making a 6-10 cab, why not make the bottom two cover the really low end of the spectrum? As in 20-30Hz, with the other 4 10's hitting the rest of the needed range... I know that adding a crossover "pollutes" the sound, but I imagine that one could make a 2-3 way setup like this that would cover any frequency you throw at it could be possible and sound good. And when looking at extention cabs (15's and 18's) they still seem to cover a fairly high frequency range... I dont think I've ever seen a bass cab that claims to hit 20 HZ (I know that numbers aren't everything, and that theres lots I havent seen) so do they exist and I just havent seen enough bass cabs?
