I ask this out of pure scientific curiosity, it is not a loaded question in any way. I have never heard any Bose speakers at all, I have absolutely no opinion .......
Please go listen to some.... any at all. I used to gleefully sell them to anyone who wanted them at Circuit City. I even toured the factory in South Carolina... it was very interesting. I noticed they used a Samsung transport and a paper-type circuit board in their $2,k Lifestyle system. It appeared that everything they produced was the product of deciding the absolute cheapest way to do it. I would guess their profit goals are in the thousands. (like interconnects, power cords, wire stands

etc...)
The reality of course, is that the sound isn't that great.... but, it's not that bad, either. The average consumer who does not discern truly great audio will think a Bose sounds great. They sound better than most average to below average systems/speakers. Their systems are highly proprietary and discourages any changes to the original design. That's probably good for the average Joe in more ways than one.
Bose are heavily equalized in all of their systems which does not appeal to a purist. They sound somewhat accurate on acoustic guitar, vocals, and some types of drums. Cymbals sound like mush, bass sounds like mush, imaging is really weird, and they're overall unconvincing.
There's an old saying... 'no highs, no lows, must be Bose'...
So, audition them for yourself. They probably won't sound awful, just completely average and passable for the average Joe. They're marketed for Joe. Since you're on Audiocircle, you're probably not Joe.
