I have tri-amplified speakers

If you are just connected to the speaker terminals at the back, there is nothing gained by tri-amping.

Bi-amping 101

This article provides a quick look at how bi-amplification works. The conventional scheme is to split the signal into two frequency bands before the power amplifiers that drive the speakers. The bass (LF) amp sees only LF signals and drives only the LF driver (woofer). The treble (HF) amp sees...

Thanks

p.s.The speakers measure well beyond my hearing range, and are the finest of the dozen or so DIY systems I've built since college.
