[QUOTE="Art Welter, post: 91001, member: 52"] Re: Subs, what to do if you lack excursion? The Omega Pro 18A needs a big box to go low, but then runs out of excursion at low power and relatively little output. I'd agree with your plan of putting four in each of your boxes, slot loaded, Fb around 44 Hz. That is fairly similar to the MT4 frequency response, which was good enough for Rob Colby and Prince back in the day. The slot should be very thin to avoid loss of cabinet volume. Raising the level by 12 dB to account for four times the power and cone area, the sim says the quad should do around 133 dB with 1600 watts. You should be able to reduce cabinet count by half, increase output, and use the empty cabinets for the wood needed for the slot plenums.
