What’s the Right Power Amp Ratio For Bi-Amping?

Bridging seems too extreme by the way, as I’d end up with the capability to produce 400 watts per channel, probably ten times what I’d ever

Not only that, but also sound quality is worse. As everything measured parameter that makes an amp a good one takes a hit when you bridge. The only plus you get is the extra wattage when you bridge, and if you don’t need it, then you actually go backwards in sound quality.

EG: Bridging Amps
CON’s:
Higher distortion
Lower current
Lower stability
Inability to drive as low impedances
Lower damping factor
Higher output impedance.

PRO’s:
Higher wattage.

One advantage of a vertical configuration is minimization of sonic effects that may result from inter-channel crosstalk within each amp, since both channels would be processing the same signal.

Hi Al, just to add, the biggest advantage of vertical bi-amping is that the whole power supply joule storage of one amp, is dedicated to just one bass driver and not shared, so the bass/upper bass should be better on big dynamic transients. (unless the amps have true dual mono power supplies) which are rare.
