Summary: I bought these about 5 years ago and they worked OK for a few years. Turned on the amp this season and only had treble, no bass. I had installed these according to manufacturers suggestions...partially buried. I dug them out and dumped them over and water poured out.
Summary: The Bose Free Space 51 , do not live up to the Bose name . They do not handle bass levels very well .And I've also had to return them a couple of times . I don't reccommend them for large areas .Invest your money on something else. I purchase them for my back yard pool area . Not happy at all.
