so I'm confused. just popped a pair of 15pr400's into my 2 music man 115rh cabs powered by a sunn 2000s. and they seem to be distorting quite a bit at moderate volumes anywhere below a Bb. i used to run this same rig with eminence cb158's in the cabs to great effect. obviously those were much more colored speakers with lower power ratings than the faital's. I took some measurements of the cabs to provide some rough specs, the cabs volume is about 3.4 ft^3 with a slot port that is 2x26 inches give or take at the mouth (slot port runs down the back of the cab and then lets out into a big flare). So what am I hearing? will this go away once the speakers "break in"? are these speakers screwed? are these cabs just wrong for the speakers? if so how? is the "flat" response of the faitals just amplifying some unpleasant sounds coming out of my sunn that were masked by the old drivers? something else? I'm confused and frustrated, any help would be appreciated!
