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!
