252chevyboyz Posted July 3, 2011 Report Share Posted July 3, 2011 (edited) Hey whats up everyone, I was wondering if some of y'all might be able to give me a few suggestions on a box or maybe a little help. I drive a '97 Tahoe (max dimensions are below) and I only have 2 Q Power 12's in it but I am looking to get away from anything prefab and try to make my own to squeeze every bit out of these 2 12's I can. I will add a few pics of what I have now and I believe the volume is something like 1.6cu according to the Q Power website. I am open to any suggestions y'all may have as to switching the direction of the port or change the direction of how the subs fire. Maybe a bigger box? I'm going to go with 3/4" MDF board and thinking of carpeting it. I'm just trying to be able to compete in some small comps with what I could get on a budget. Thanks in advance for any help.

252chevyboyz Posted July 3, 2011 Author Report Share Posted July 3, 2011 (edited) What do y'all think of maybe moving the port to the bottom? Or maybe two smaller ports at the bottom (one under each sub?)

Supercharged DCs Posted July 4, 2011 Report Share Posted July 4, 2011 I entered your box specs, came out to 2.63cubes tuned to 37hz with 9.7sqin per cube of port. Pretty bad box, but that's to be expected of a prefab. My design is 16Hx34Wx20D Port: 14.5Hx4Wx25L Woofer displacement is .21 for both your subwoofers I believe, your box will be built with 3/4" MDF with 2 common walls. Comes out to 3.67cubes net, tuned to near just below 36hz, and has 15.8sqin per cube of port. Sub upward, port firing towards rear. Nothing special about my design, but I promise it will be a improvement over your prefab... Quote Bassless once again.
