Paul, i doubt if the switchbox halves the impedance. If anything, the switchbox may have impedance compensation built into it. This is a form of "protection" that simply RAISES the impedance that the amp sees if you have several speakers selected at once.
As such, they probably make the "4 ohm capable" comment simply to remind you that selecting multiple speakers can provide a low impedance load to your amp.
As to hooking up a speaker switchbox to your amp, that would STRICTLY be a matter of convenience. If it did anything to the performance of the system, i would say that it would be to degrade the sonics via the cheap wiring, switches and jacks that it would make use of.
Given the desire of some folks to do something like this, i have to wonder why nobody makes a high quality switchbox for situations like this ? If there is one out there, can someone point Paul in the right direction ? Sean
