Thanks, Dennis. I wound up using what you suggested -- I wound up with a 
turnover of 800Hz and a 10kHz rolloff of -12dB. And you were right about 
the surfaces -- this was dreadful; I needed to roll off at 80Hz (which I 
got away with because the lowest instrument was a guitar, and not one 
with a lot of bass at that. With all that, I needed to use 4dB of noise 
reduction too. But I got something that I can play on the radio, with a 
disclaimer first.

Thanks again!

Peace,
Paul
