You are decreasing the bass output by placing them on 9" stands. Get spikes and get them back down on the floor. This should help somewhat w/the tonal balance.
You didn't mention what amp you're using, but perhaps the speakers are revealing hardness in the mids & highs that is upstream.
Midrange shouldn't be "popping", and they certainly should be able to play 90+db w/o a problem. Your midrange could be blown. Have you tried listening to test tones to see at what freq. the popping occurs?
Call Carl if you can't figure it out. His Nola company is still doing fine. Cheers,
Spencer
