if you want more low end do sealed a 2 cubic feet before displacement of the subwoofer id assume its .20 cf for those subs because the magnets are decent size so total internal box volume would be 2.20 cf sealed....if you want more upper end bass do a 3.00 cf box ported to 34 hz plus .20 cubic feet for displacement of the subwoofer for a total of 3.20 cubic feet internal air space your port would be two 4 inch pvc tubing ports inner diameter 16.5 inches deep
sean, since your on this post, could you please help me, im totally lost, and today i want to expieriment around with a box, could you please give me dimensions for a 3 cubic foot box including the ofset because of the magnet of the 15 eclipse TI, can you please help just throw together some quick stuff, and iw ant to port it to 28 hrtz any chance you can just give me a diagram real quick lol with paint with alldimensions lol
if you want my honest opinion on the kicker l7 12s id say do one l7 12 and a good 800 watts rms and youll be better of in the charging department for your alternator and you can use more room for box and make up the spl lost for the second 12
ok heres one for you 2.02 cf rear chamber 2.23 front chamber 12.75 inch deep port 4 inches inner diameter (front chamber) this is a bandpass box for 1 l7 12 kicker and more than likely will be very loud with as little as 400 rms power from an amp this is using the dual 4 ohm version a you could do a mtx amp class d like the 6500 d mono block or newer models for this sub for 800 rms to the sub at 2 ohm load bridged....it will hit nasty loud in this box
i have a volfenhag 2000 watt 2 channel brigeable amp the zx-8400 model. it is powering 2 600 watt rms volfenhag 15" subs. i have them wired in a parallel series and are bridged at 4 ohm. the amp has a 100 hz subsonic filter. i dont know if that will help any but if you have any more suggestions it would be greatly appreciated
the 15 inch Eclipse TI, and im powering it with a jbl1200.1 with 1200 watts rms lol, i want to do ported, and glass said that it would be best with a 3 cubic feet tuned to 28 hrtz, but i cant figure out ports or anything and i have 1 1/2 inch pvc pipe to work with. im just so lost on the whole thing, i cant figure out displacement or anything lol
ok i got the specs for it...it looks like glass already figured out the sub displacement if the sub has a big magnet and basket the ports will be 3.5 inch ports inner diameter there will be two of them 22 inches deep.......let me know the demensions we got to work with
ok heres one for you 2.02 cf rear chamber 2.23 front chamber 11.61 inch deep port 4 inches inner diameter (front chamber) this is a bandpass box for 1 l7 12 kicker and more than likely will be very loud with as little as 400 rms power from an amp this is using the dual 4 ohm version a you could do a mtx amp class d like the 6500 d mono block or newer models for this sub for 800 rms to the sub at 2 ohm load bridged....it will hit nasty loud in this box ....in all honesty over 400 rms watts your probably going to have some port noise but the box will bang reguardless at that amount of clean power id prob go a shade over say 500 rms all while being easy on the alternator
to figure out cubic feet you multiply length times width times height and then divide that by 1728 and youll find your cubic feet but remember that is internal space not including wood thickness or the space the woofer takes up or your ports if you have any
