I just felt I had to voice my opinion about these systems. A lot of folks rave about them but I think they are awful! I have played through many of them in different rooms as a solo piano/vocalist over the last couple years.
The high end that sounds really harsh to me - sort of a crispy metallic high end. The rumbling low end has no definition, and the whole system has almost no midrange where the voice and the middle of the piano need to be in a mix. Think about it - how can you achieve a defined low end with a sub? You can't. How can you get warm mids from tiny metal speakers? You can't.
The cool thing is they get the sound all around the room - but then again, some people sit in the back to talk and not hear the music so much.
The systems are really expensive for what you get when you compare a pair of speakers and a mixer at almost half the price. They are not so easy to set up - and really not that hard either, and they really aren't all that light. They take up a ton of floor space in one area. The technology is pretty cool, but the sound is less than great in my humble opinion. (I've been playing in clubs for 32 years and making a solid living at it for 25.)
My wife has an Infiniti G35 that has a Bose system too. Used to be the old saying "no highs no lows, it must be Bose." Her car is so bass heavy it's ridiculous - the CDs I listen to all the time sound terrible in her car. I have tried to adjust it but the problem is there is no graphic EQ, so if you take down the thunderous hip hop bass, you also take out the bass you need for a kick drum and bass guitar.
I'm not planning on spending any money on anything Bose in the near future. Sorry, I just don't get the hype. The prices are sky high!
