speaker grilles


Here is question I was asked the other day. How much listening improvement is gained from removing the speaker grilles? Do manufactures assume you will listen will the grilles off and supply them only for looks and keeping dust off while not listening?
Thanks

I think all speaker sound better with grills off. Theil is another that says they designed with the grills in place. I think it is a sales pitch. It's like "hey we build such a great speaker and design such a great cabinet that our speakers sound better through fabric"?? Take 'em off, take 'em all off!
I was told by my dealer that JM Lab voices all its speakers for use with the grill on. In practice though, when I took the grills off, the sound opened up, detail improved, and the soundstage widened by about 6 feet! So I don't buy that claim.

I think manufacturers say these things so that people evaluate a product's aesthetics with the grill on rather than with the grill off. Most non-audiophiles prefer looking at grills rather than drivers. The WAF factor, maybe.
My JM Labs also sound better with the grills off...although my soundstage doesn't grow 6 feet! Dag nabbit.
i myself try to avoid pulling the grills off of my speakers as much as possible,from what ive heard in my systems any sonic improvements are so small(if any) that its not worth the risk of damage from constantly handeling them.
