Hi again Frank,

You're welcome. I am envious of your setup since my HT is in our living room, which requires all sorts of interesting compromises.

Clean, powerful output at 20Hz is more than adequate for all but the most challenging material, in my opinion...

Matching sub output to your speakers without a meter will range from extremely challenging to impossible. You could use the 990 auto setup if you don't want to mess with an SPL meter. If you change your mind and decide to do it manually with an SPL meter, be sure to check out this thread on AVSforum. The Radio shack meter rolls off at very low frequencies.

Since you have two sub outs on the 990 you would not need a 'Y' adapter.

Cheers,
Tony.
