Thanks for all your suggestions. That was very helpful. Yesterday I tried them out and I think I found the problem in going through them. under "bass setting" the Denon amp. allows you to pick the crossover at 80 hz ("LFE at 80 hz") BUT, lower down on the speaker setting menu there is a separate line for the crossover, which was at "fullrange" for the mains. I put that to 80 hz. And now: the subwoofer will turn on automatically more readily and it fills in more than just very low tones. So I am keeping it at the original Audyssey settings. NOTE--when I did it as LFE and not main=LFE it didn't sound good at all. There is no "sub only" feature on the Denon. while my kids were indeed hoping for the greater bass/thump for pop songs, I'm glad now that jazz/classical/folk is fuller now. Another question--the sub also has a feature for the Phase setting, from 0 to 180. The manual wasn't very clear on where to put that. What would you recommend? Thanks again for your time.

To complete a 2.1 system, I just bought (used) a RW-10d subwoofer to go with two Synergy floor mains (used) and a Denon AVR 590 amplifier (for a Panasonic 42" plasma and blu-ray player, all new). The set up is in a 10' x 16' furnished basement room. I did the "Audessey" calibration with the little microphone. The Denon manual asked to put the subwoofer volume at the "12 o'clock" position for the sound check. Wiith the RW-10d digitial display I wasn't sure what to do so I put it at 0 db. The Denon manual suggests the cut off for the mains be at 80 hrz (for "large speakers"). The sub is connected with a single good quality cable and the amp is set to "main+LFE" I think. (Sorry a lot of this lingo is new to me.) In the end, Audessey settings have the channel output of the left and right mains at -5.0 dbs, and the subwoofer at -12 db.As such, I don't hear the bass that much, with the mains doing most of the work still. Do I a) increase the volume of the subwoofer with the control on top? OR increase the channel output for the subwoofer with the control on the amplifier? c) redo the calibration with the subwoofer volume at the top, 12 dbs? Options a) and seem to defeat the purpose of the Audessey calibration and I'm not sure if c) makes any difference. I am half tempted to resell the subwoofer and just live with the mains, which do a nice job in the room already. P.S. I have tried both options a) and at once and that shakes the dining room upstairs!
