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 |
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 :D
|
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? :appl:
|
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 :D 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 |
