New set-up does not sound the way it should.

[Glen B]

Deep, satisfying bass with most rock/popular/jazz music goes down to around 30-40Hz, and even lower with pipe organ music. When you set a crossover frequency as high as 80Hz, you're rolling off all that deep bass. "Rolloff" means the level of low frequencies decrease as you go downward in frequency range. One other thing, according to the speaker specs you listed, the LF cutoff is -20dB @ 32Hz, meaning the bass level is down 20 decibels at 32Hz. That is a pretty significant bass rolloff. You can try placing the speakers closer to the rear walls to help reinforce the low frequencies.
