I’m curious as to what improvements one gets if they bi-amp Westminster GR’s.
Any comments from those with actual experience appreciated.
I can guarantee no one here has a pair of those speakers.
The electrical crossover is 1000Hz. Now we generally discourage passive bi-amping as there is no point. However in this case with the crossover being that low, as long as you used identical power amps you might get between 1 and 2db increased output. You won't get significant power increase as the crossover is 600 Hz above the power divide at 400 Hz. Since these speakers are 99db I watt one meter efficient there is not much point. These speakers are in the province of tube amp owners generally, so may be there might be trivial gain. Max continuous power is 170 watts, so most solid state amps that would be associated with speakers in the stratospheric price range of these speakers, would drive them hard enough to cause permanent deafness.
It is absolute nonsense that tubes give better sound that good solid state amps. That is objectively untrue and a tenet of blind faith among the audiophool community. So the best way to drive those speakers is from a good solid state amp in the 150 to 200 watt power range.
Other members might be confused about the passive 200 Hz crossover, from a single cone and coaxial horn electrically crossed at 1000 Hz.
The 15" is loaded by a horn front and back, and the 200 Hz crossover is the transition between the front and back horns. However this is not a transition that can be biamped.
