Ok,
So after doing some listening, I'm not sure what is going on. My Logitech Z-5500 sub is stomping all over my PC13-Ultra when playing music. I specifically got 2 bass cds for listening: Bass 305 and Bass Mekanik. I have more on that subject, but that goes beyond this thread.
Listening to tv via Direct TV, or watching movies is fine. In some cases the bass is way more than I'd expect. It's when I play a cd that the bass, well attenuates is the best word I can describe it with. It starts off good, but when I increase the volume the bass output lowers on its own after a few seconds.
What could be the culprit? Could it be Audussey level matching? I tried hitting the pure audio button on my receiver, but turning it up after that was too loud in the main channels and still lacking a bit on the bass.
