I have two Bose Lifestyle 5 systems. These things are about 16 years old (or so)...
I didn't buy them for their sound quality, thats for sure. I bought it for the concept, and the fact that they play LOUD.
One system is in my garage, one system is outside in my entertainment area. Both are linked together, i Airtunes to them too.
The best thing about the systems? the wireless remote. I love it, especially when having guests over or throwing a party. So easy!
Having the 'cubes' attached high on my outside walls and in the garage works really well, not so obvious, nice coverage of sound.. and they blast!
Wouldn't buy BOSE for SQ.... of course.
Mmm they don't go THAT loud. They have pretty weak amplifiers behind them, and generally very small drivers (incl. the subwoofer). A pair of say, Klipsches will go much much louder, especially if you add a subwoofer...
