Ditch the internal xover and use the sub....

Was helping my son with his system last night. He has a Sony HT receiver and uses the pre-outs to drive Parasound amps into a pair of Mackie studio monitors as mains. Also uses a Velodyne FSR-12 sub.

No matter how we diddled the settings, the sub was boomy and nasty. Finally, I ran the pre-out directly to the sub and sent the high-pass line out from the sub to the Parasound amp. Designated the Mackies as "large" so the LFE went there instead of to the now-unused sub out. HUGE improvement. Hard to believe the Sony internal Xover was that bad or that the Velodyne was that much better (I'm not a fan of either brand). Any thoughts?

A friend uses two subs. The first comes out of the sub output from his denon home theatre receiver (avr 3801); this is a McIntosh HT-2 passive sub (dual 12" woofers) powered by two channels of a Parasound hca 1206 (bridged for 350 watts). This provides the bass for home theatre duty.

The second sub is a fairly old Mirage PS180 (180watt, 12") and gets its signal from the speaker wires for the pair of Linn Tukan front stereo speakers. When listening to stereo only the McIntosh sub is not used; when listening to DVD material then both subs are used.

The results are quite spectacular; and that is when listening from the porch. The new neighbours are not impressed favourably.
