I agree with you, but his original post did not really specify much more than a 15 or 4 10's. My thought was that he was looking for output, not a freq. range to match. From what I have gathered, I he was looking for out of the ordinary. In that case, go with 3 15's //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif//content.invisioncic.com/y282845/emoticons/drool.gif.b5e863e893038027711d4402f340dad0.gif
If output was the goal, and no budget is specified, I'd wait for the pending forum boner.
Now if quality sound is what you are looking for....actually, i'm not going to guess...what EXACLTY are you looking for (to the OP)? Output, SQ, SQL, SPL?
