Summary: These speakers are great. Much better sound quality than expected and very bass-y. I bought them to mount in my classroom as rear speakers for a 5.1 system, but they sounded so much better than my pioneers that I put them upfront instead. The mounts aren't anything special but they will hold. I suppose you could use them as bookshelf speakers but the speaker tilt might make them look a little funny. If I ever get a a backyard I will definitely get another pair.
Summary: Speakers are nice. Responsive and good sound. The mount though was clearly designed and never tested. It does mount to the speaker ok - but mounting to the wall is not thought out or tested. First - I have 2 pairs of these speakers so what I observed is not a one off. 1) The included screw heads dont fit through the key hole unless you angle the bracket at 45+ degrees while you put it on, which results in a loose hanging speaker.
Summary: I bought 2 pairs of these - front and rear surround speakers for 5.1 home theater system, for a medium sized rec-room. Works like a charm. Paired it up with a "Dayton Audio CCS-33B 3-Way Center Channel Speaker - Black" and I'm a happy listener!
