Right now I have 2 AQ SDC2.5 15's in about 10 cubes net @ 35hz with 144in^2 of port. It's loud, but the box is huge, and I'd like more cone control at lower frequencies. I was planning on building a new box, 8 cubes net @ 32hz with 2 6" aeroports. This design is a lot smaller, but I'm worried about losing output. I've always used big slot ports, so I don't know what to expect. Will it still be as loud?
