Query: Beware of These Speakers!!!

I had a very similar experience to "W. Bailey" and "Phillip Crosby" below. There is a fundamental flaw in the design. The sound on the secondary speaker will get very shaky (i.e., play inconsistently). Minor fiddling with the on/volume knob will restore the sound temporarily, but slowly and surely, the connection to the secondary speaker will become gradually more and more tenuous until you are pretty much left with only one functioning speaker. Again, given the similar experiences of other reviewers, I strongly suspect this is a fundamental flaw in design. In sum, AVOID THESE SPEAKERS if you want them to last more than a year.
