In Reply to: The Subwoofers You Designed Duke Are GREAT !!! posted by ka7niq on December 14, 2009 at 14:53:15:
I had 2 x dual 18 push pull subs.......... Lots of pulse and pressure, but not slam (crossed at either 100hz@24db or 80hz@18db).
Slam was either a w-bin (7ft3 area of mouth, best kickdrum I've ever had) or 4 x 15" woofers (in additional to the subs).
What is funny is I ran a 15" as baffle step (with inductor only). At low volume hooking it up there was no audible difference, but the louder you got, the more the difference the extra 15" made (like old stone temple pilots).
That is the kick drum that hits you in the chest. That's the 100-200hz range.
It might be time to stop the "retail thing" and start doing the active crossover tri or quad amplifier.
