sweet&low Posted December 1, 2010 Report Share Posted December 1, 2010 2005 Pontiac Grand Am. Goal was to build a wide range 4th Order enclosure. We succeeded plays from 28hz - 72hz efficiently. Last time it was meter it did a 141.7 on TL. It has DD Mids and Highs on a DD C4b. Subs are 2 DD1510's single 4ohm on a DD M1b at 2ohm so the subs are getting about 800 watts. http://www.youtube.com/watch?v=goyH8pwii_s http://www.youtube.com/watch?v=yuJeycunQWU http://www.youtube.com/watch?v=yTQuG9SaS2A http://www.youtube.com/watch?v=O0449nBWbkw Quote Link to comment Share on other sites More sharing options...

sweet&low Posted December 2, 2010 Author Report Share Posted December 2, 2010 This one has a very even wide frequency range was built for daily driving and no competition. Everyone I have put in the car is amazed by the low notes. Quote Link to comment Share on other sites More sharing options...

sweet&low Posted December 2, 2010 Author Report Share Posted December 2, 2010 how did you design for such a flat and wide range?? Would love to tell you but one of my secrets. Its lots of math and tuning. You also have to no the frequency response of your car because it works very closely with the car. If you took this box and put it in your car it would be totally different sound and frequencies. Quote Link to comment Share on other sites More sharing options...
BulletInjection Posted December 2, 2010 Report Share Posted December 2, 2010 how did you design for such a flat and wide range?? Combination of the sealed chamber size and ratio of the I guess you would say ported half of the enclosure.

Combination of the sealed chamber size and ratio of the I guess you would say ported half of the enclosure. Ya ratios have alot to do with it. But like I said its designed just for that car. If this helps out I use Bass Box Pro 6 to design all my enclosures. The program give very good and close to real world graph read out if you have it setup right. Wish I had my other camera that broke where I could plug in the external mic to show the sound quality. Quote Link to comment Share on other sites More sharing options...
