Should I burn these?

Am so disappointed with my Bose 911 speakers. I appreciate good sound quality and these speakers just don't cut it. They do not possess good sound performance as far as highs and lows and the sound is very flat and muffled, and no they are not blown. They have sounded the same way since they were new about 5 years ago. Had an old pair of Canadian made speakers made by Audio tec from the early 1980's and wish I would have kept them as the sound was far superior. Bose 911 speakers are over priced and the sound quality sucks. Don't buy them!!!
