Here is a short segment from the review:
 Quote:

The Bose system is very expensive at nearly $2,000 and the sound quality isn't really any better than many other surround systems costing a third of the price. The cube speakers seem to roll off on the higher frequencies and leave the treble lacking. The sub module has two 5.25" cones that produce a decent mid-bass thump, but can't really fill in where the small cube speakers left off.
