Ported box too large?
I bought two TS-W1207D2 Pioneer Premier 12" Champion Series Subwoofers and I started doing some calculations on the box I have rightnow and it would seem the box is too large specs of the subs are as follows
TS-W1207D2
Premier 12" Champion Series Subwoofer with 1200 Watts Max.
IMPP with Aramid Fiber Cone
Integrated Single Sided Silver Binding Posts
Recommended Enclosure: 0.85 to 1.75 Cubic Feet
the entire box is 4.7 (rounded up from 4.68....) so 4.7 /2 (there's a divider in there) is 2.35. so each sub has 2.35 cubic feet and as stated above the subs need .85 - 1.75 cubic feet. what are my solutions for this problem? without cutting the box preferrably. Thanks

Did you include port displacement and sub displacement aswell? I also find that its ok to give alittle headroom for airspace in the box(ie: Type r's recommend 1.75 cubic feet, but people build boxes 2-3 cubes because there is greater output.), so you should be good.

actually 2.35 is not bad for a 12" sub
specially if you want SPL..even SQ it will be fine..as you are tryinh to increase the lowest octave of teh sound spectrum
the larger the box..the more output at lower frequency... depends on box tuning
