[QUOTE="Beatin', post: 8265248, member: 646085"] I like loud too. However, what's the point of having "loud" if the roll off of a kick drum plays like crap because the beginning and end of the signal want to play out of the port at the same time due to group delay timing differences? one-note bass lines and synthesized percussion is fine with high group delay but when a signal goes through multiple frequencies in a split second, high group delay is a major problem. This is where I see high EBP subs having an advantage. Some of these low EBP subs need such HUGE boxes for one 15". And still they have two huge group delay peaks above 20ms and a trough around 10-15ms. Outside of the group delay peaks within 10hz the group delay drops to below 10ms. Looks like a disaster.
