Yep, google Bose quality and you'll read all you need to know. Not very popular with audiophiles ;)

If you are going to replace speakers do it right the first time and replace the tweeter as well. Do set of components and they sound better than any coaxial speakers.

I agree with the recommendation for these, almost direct fit as well. Make sure t run new speaker wire to the woofer and tweeter.
