Summary: the sound quality of these speakers is exceptional for the price however the mounting screws and anchors are insufficient. I mounted them on the walls near the ceiling in my office, approx. 6' across from each other angled down 45* and did the Bose test. their recommendation is to set the tone controls on your receiver to 12 o'clock (flat) & play a music source with full audio spectrum from low frequency to high frequency. after doing so adjust tone to taste.
Summary: I have these speakers connected to a mini amp in my service truck so I can have music while I am working on equipment. Put a couple of magnets on the speaker mounts so I can pretty much put them anywhere on the truck (within reach of the allotted speaker wire). Excellent sound quality. The bad, the speaker wire connectors in the back are flimsy, and barely hold the speaker wire.
Summary: I have a large home and have 8 pair of these all though out my home. Great by them selves but I added 3 Polk 10 inch subs. The sound can't be beat! They fill most of my 5000sq ft home with excellent sound!
Summary: The performance of the speakers has really been impressive. I imagine the negative reviews are the result of people not getting a good signal into them, perhaps a bad amp or stereo. I think they sound great, a very well balanced sound and volume to spare.
