Input:
User Review: They're great speakers.  Wonderful sound.  They're driven by an Onkyo TXSR605 receiver, and the combination is perfect.  I'm not an audiophile, just someone who wanted to build a nice theater.

My only complaint, which is very minor, is that the tabs on these speakers are not as good as the ones on comparable Bose flush-mount speakers.  The tabs on Bose speakers that I installed 2 years ago positioned themselves and held the speaker against the drywall perfectly.  These tabs have a tendency to "catch" on the speaker housing, and then they never squeeze the drywall.  When you install these, make sure every tab is free and clear before you tighten any of the screws.  Otherwise you may get 3 or 4 of the screws tightened down and realize that 4th or 5th tab is messed up, and you'll have to start over.  You might want to "help" the tabs get into position with a flathead screwdriver or a butter knife while you screw them in.  Once you get them positioned and tightened down, the speaker is solid and doesn't vibrate or move or anything.
