Looking for knowledgeable designers input on a thought I had the other day. I imagined an 8x8 (or 8x10) three way cab. A pair of good robust subs in a ported enclosure, a bandpass 410, and a pair of mids. Three chambers, two port tuned. I'm figuring the sub chamber and 410 chamber tuned an octave apart, maybe 30 and 60 respectively. Using something like 70/3k as the filter points. (these numbers are just thrown out there). The 410 basically running full range, but high passed at about 70, low passed at around 3k, with a sub and mid drivers taking care of some content on either side of those two points. Okay, learning hat on. Poke some holes in my concept before I dive into searching drivers and modeling. A couple things I already know: Big and heavy. Could easily be a mud-maker in high volume situations, and the "sub" is overkill and unnecessary when FOH is present. It could be a power-suck, with low sensitivity subs eating up the majority of the amp's power. Responses to those: Wheels. Made for use when no FOH is present, two L-pads. Possibly a way to bypass the sub chamber, or give it an independent input. Details, details. First I need to hear if it's a case of physics not caring that my logic says it might work, lol.
