carshateme Posted January 22, 2012 Report Posted January 22, 2012 First time using the Torres calculator so I have no idea what I'm doing here, But I'm going to be purchasing 2 dc level 2 M2 12" subwoofers my next paycheck and I'm gonna try to make this box look as good as possible and sounds as good as it looks. Um, I want to tune it to 31 hz..or whatnot. I listen to dubstep, techno, some rock, and rap. My max dimensions I can work with is 15 x 34 x 22...but I'd like to keep it under 14.5 x 33 x 20...considering the trouble I had getting my last box in which was 15 x 35 x 24. Here's my calculations so far. As I said before I'm a complete noob when it comes to torres calculator. I'm going to be throwing their maximum RMS power at these subs with a quality amplifier, which down the road I will purchase. It will be ported...mostlikely a center port b/w the subwoofers. New build coming soon. [center][url="http://imageshack.us/photo/my-images/3/sigtoo.jpg/"][img]http://img3.imageshack.us/img3/9541/sigtoo.jpg[/img][/url][/center]
412 CVX Posted January 22, 2012 Report Posted January 22, 2012 net volume is a little small. Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.
bassrace Posted January 22, 2012 Report Posted January 22, 2012 2.5 net for both? That's a small box. Try external aero (if possible) to get the space you need for 2 12"s. 145.9@40hz 145.3@34hz big 3 X2 group 34 Deka Group 31 All 0/1 awg jl meta wire Alpine CDA 7894 Orion HCCA D5000 2 AQ HDC312's Crunch gpv1100.2 (for 6.5"s only) AQ pro audio 6.5" - 3 sets AQ supertweeters - 2 sets 2000 Slamry
carshateme Posted January 22, 2012 Author Report Posted January 22, 2012 Now for an external port, is a circular port the only available option I can work with? and the volume for both subs only need to be 2.5...or what I though, since the recommendation for one sub is 1.25 cu ft. But I came up with a new calculation, so how's this one? New build coming soon.

AI James Posted January 22, 2012 Report Posted January 22, 2012 looking at your gross volume i wouldnt even waste the money to purchase 2 subs
Joe X Posted January 23, 2012 Report Posted January 23, 2012 Despite their recommendation these subs will give poor bottom end on low Vb. Fs = 31.3Hz Vas = 2.8 ft^3 Qts = 0.491 You can check Frequency response with this: http://www.linearteam.dk/default.aspx?pageid=newdriver
