Query: A true gem.

I love my sls speakers. Makes my home theater experience phenominal. The subwoofer is the size of a small cabinet. Everything is crisp and clear. I worked with sls speakers in the past and love em. Highs mids and lows are very nice. Considering how much I paid, I could have bought systems 3 times as much and wouldnt have been half as nice. Its a steal get it.
