Cabin gain is gonna throw off most box building programs. I like to run a frequency sweep in a sealed box and record the response and subtract the predicted response from the actual measurement. This gives me an idea on how the cabin affects things. But this requires some measurement equipment. With enough power I think you could make 1cube per work but you suffer on the lower end at rated power. Could you use aeroports to save space? 7in² per cube works ok 10in² per cube is were I like to be. I ran a single 4inch in 1.5 each without port noise but I wanted a touch larger port area.</blockquote>
