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

 

If ya wish to decrease the volume, drop some bricks inside. Secure them of course .

 

lol ACTUAL bricks or a brick of rubber or something?

 

I found a Phone book works rather well :P haha, Or Citrates way is to drop a case of pop in the box!!! IT worked for him

 

LMAO guess thats a place to store pop when I get caffeen withdrawls just rip apart the box and let the pop sit for awhile and I'm good?

 

new subject WTB: 2 edmonton or equivalent phone books for sub box since my area's phone book is only 1inch thick, lol jk

 

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.

 

The maximum volume you want to go with for that sub is 2.05 cubes in a ported enclosure. As suggested, you can pile in some bricks or extra lumber (4x4, 2x4) to take up some of the extra volume.

 

Or brace the crap outta it, then it serves dual purpose No flex, and takes up displacement!!

 

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
