ok, so going to build this box tonight, or at least start cutting, so kenwood recommend a box size range of .80 to 1.75 cuft, of that range they say the best size for this sub is 1.25cuft, now my max box size is 3.22cuft (1.61cuft per driver)which is 30"w x 15 d x 16 h. should i build to kenwoods spec or what size i have avalible? then my next qestion which would define the above is, what difference in sound, bass and any thing else considered would 2.5cuft or 3.2cuft make? i ask because if kenwood (or any speaker company's specs) state this is the ideal box size then i would have thought it would be best to do so to get the best from the driver if it is housed in a lager box, how does this effect its thiele small parameters. ie excursion, resonance and the way it performs? in simple terms i guess, which size will produce the best sq bass and performce?
