I am getting some 15" btls. I was curious about how I should get it made. I know I want the p-chamber. I read that if you get the 3rd magnet with no cooling option, this is better for SPL. So, what happens if you get 3rd magnet with the cooling option. This is going to be a daily driver with, hopefully tons of SPL, but I don't want to kill the sub and replace it or fix it consistently. So, which option with these should I go with?

Daily driving you are better off getting full cooling if you plan on running in excess of 2000 watts to each sub.

should i still get the 3rd magnet?

hey man,

i have a loaded btl 15 daul 2, and a 2500d running it.

sounds awsome on music, and slamms its but off, does 159.9 in the port which is 75insq. pretty good for a port that size tuned to 32.

150.7 in the kick, dont worry to much about getting tons of spl, THEY ARE BTLs YOU WILL GET TONS OF SPL.

JUST MY OPINION
