detroitdb Posted February 28, 2013 Author Report Share Posted February 28, 2013 why do you want to tune a 4th to 72hz?....most 4th are tuned in the 40s-50s actuall i want a ground pounder, with decent numbers now I could see tuning the front chamber of a 6th 72hz and the rear in the 30s Actually that spec came from atomics website, I thought it sounded crazy high too. After learning of the smd forum, I cant believe how much I truly dont know about car audio. I could always install and figure out anything you could throw at me. (except enclosure building) but i am learning more every day. don't listen to the atomic website specs. are u looking for peak spl or good output on music? https://photos.google.com/photo/AF1QipP7rjav9cD9UFdAYBJmz4M4LoNlF26ng1xhAf4Uhttps://photos.google.com/photo/AF1QipP7rjav9cD9UFdAYBJmz4M4LoNlF26ng1xhAf4U 2013 DODGE CHALLENGER R/T SUNDOWN ZV4-18 CRESCENDO 3.5K PIONEER AVIC 5300 NEX ALPINE TYPE R 6.5S & 6X9'S ROCKFORD FOSGATE 1.5" TWEETS 5 C&D TECH BATTS Link to comment Share on other sites More sharing options...

Goblenator Posted February 28, 2013 Report Share Posted February 28, 2013 6th order. Rear chamber 7.5 cu at 30hz front chamber 2 cu at 59hz. Thats by far the best i could get on winISD. the atomic speakers are very difficult to make enclosures for. They are very loud but sq can be an issue.

Also, for the rear chamber am i placing the port and woofer on the same side loading into the front chamber?
