Bose speakers are A-weighted. There have been no A-weighted commercial designs since the 1970s. Imagine feeding a signal that is flat in amplitude into Bose speakers, and the output you get looks like a semi-circle. Bose speakers have generally been good for old people because they focus on the mid-range frequencies and drop off everything else. If you want to watch action movies without hearing much noise (yet still hearing dialogue), this is the speaker for you.
If you are buying speakers for music, Bose is probably as bad as you can do. They are not accurate. If you like your music A-weighted, listen to A-weighted music, don't buy speakers that are A-weighted. If that logic escapes you, imagine having the choice of two cars, A and B, at the same price. Car B is worse in every measurable performance aspect. You like to drive slowly, and thus choose Car B. Now you could buy the more fuel efficient, more powerful car, but instead you spend more for a slower gas guzzler because you think buying a slower car is a good idea if you don't like moving fast. If this analogy escapes you, enjoy your Bose speakers.
