Hi Paul, thanks for the heads up! I did rewrite the question a little and sent it to (Critics) where I have seen he jumps in now and then. I just want to see if I can get an explanation to what I asked. Paul, the only way a grill can make your speakers sound better between the tweeter and woofer or mid range is to give you the satisfaction that if you have a cat,ect.,he or she won't destroy your investment. Maybe tone controls and L-pads will alter the sound but I think grills cause (muffling and difraction)...am I wrong Paul, I don't care if I am, I just want to learn......thanks Paul for picking up on that.....Mark Korda
