elastic Posted March 20, 2010 Report Share Posted March 20, 2010 the more xmax a driver has, the more air is moved which is needed for low end bass, right? so can i compare drivers xmax to decide its deep bass potential? my 15 L7 build my youtube channel with lots of L7 videos Link to comment Share on other sites More sharing options...
bassl0va Posted March 20, 2010 Report Share Posted March 20, 2010 the more xmax a driver has, the more air is moved which is needed for low end bass, right? so can i compare drivers xmax to decide its deep bass potential? nope, doesn't work that way. Its a combination of things. Fs is very important, the lower it is the lower the sub can play and still work to its potential. Box design is another big one, very important, you arn't gonna play 25hz in a pre-fab tuned to 60hz. Also pay attention to cone area one 8 isn't gonna hit the lows like one 15 will, or 8 12s. xmax is only how much the coil can move AND STAY LINEAR, it can go outside the gap and get more excursion but it wont be as linear, but you probably wouldn't hear a difference.

elastic Posted March 20, 2010 Author Report Share Posted March 20, 2010 so for example comparing the Fs of an 18 btl (31 hz) and a 15 l7 (26 hz) the l7 should play deeper? cone area differs just by 200cm². my 15 L7 build my youtube channel with lots of L7 videos Link to comment Share on other sites More sharing options...
Decaf Posted March 20, 2010 Report Share Posted March 20, 2010 not necessarily, its the combination of parameters a kicker L7 should not even be in the same sentence as a FI BTL box has more to do with it than anything Link to comment Share on other sites More sharing options...
immortal_82 Posted March 20, 2010 Report Share Posted March 20, 2010 Actually it need to see all parameter/ spec of sub, then can compare it.. Link to comment Share on other sites More sharing options...
DarkTinman Posted March 21, 2010 Report Share Posted March 21, 2010 a kicker L7 should not even be in the same sentence as a FI BTL x2 Link to comment Share on other sites More sharing options...
