It's hard to say since Bose has always refused to give any meaningful specs on any of their speakers. I listened to them years ago and absolutely hated the sound (with and without the eq), but maybe they've changed them since then...

Perhaps you can find a local audio store that will let you try a few different center speakers in your home so you can check how well they blend in your intended environment? That's what I'd try to do if you can.

That said, I've seen/heard the Magnepan MMGs used as centers with quite good results. You may even prefer them as mains over the 901s. 8-) They're only about $500/pair and I believe you can try them at home and return them if you don't like them. Check Magnepan's web site for details.

Cheers,
