Sorry for this delayed post, I was away. The links on the other side of the world to schematics are gone. They should have been attached here.
It is probably not the boost opamp clipping in my circuit, it is probably your power amplifiers that are clipping.

My boost circuit boosts bass +14dB that needs 25 times more power (!) from the power amplifiers.
My amplifier has plenty of extra power to do it without clipping and my speakers survive.
