One good feature of my 6 channel receiver is the option to use the surround back channel to power up a sub. Got a an active sub hooked in the .1 channel of the receiver and had not tried the option until last night. Played different vocal and instrumental CDs and find the bass more musical and tight, best for most of my acoustic music selections such as the album The Only Fonta by Yongli Chan. For instrumental The bass in Richard Palalay Trio feels real. However, the bass drum on the album Sheffield's Drum and Tracks lacks the power i want despite adjusting down the five channels to almost 0 level while the sub is set to 10 and volume to -20. Overall assessment - Excellent for music except to some pieces that requires extra bass
I havent tested it yet for HT.
What i have in mind now is to buy a passive sub so i can use this side by side with my active sub. But is this possible?
