Ok...to clear up some misconceptions in this thread...Jntar did a good job though. The problem with that box, is that the aeros do esentially make about 1/3 of the box "un-useable" Throwing the tuning into the 50s. STILL with that box the Mag did a 146.1...BTLs score was lower, but because the MAG is idiot poof, and will sound awsome and get loud in just about anybox. New box will have external aeros...the wood for the new box is in my truck currently, and I will post a build log tomorrow.
As for Hair trick...meh, I would be surprised if it did a hair trick. Even though I peak in the low 40s, high 30s, still has to move alot of air.
My goals for the new box, no testing what so ever are...Burp High 40s (48-49 region) and BassRace a 46-47. after some tuning, rasing my peak to about 43, and some serious testing over the xmas break...hoping to burp a 51 bassrace a 48-49.
