@bombaywalla , your calculations make perfect sense. I was just wondering if there will be any improvement if the OP uses 2 x XA30.5 in a biamp configuration ? I am not talking about bridging the amps to use as monoblocks but actually using proper biamping, whats your take ? Will the amps perform better, with more headroom ?Hi Pani,
nah, biamping will still not do it for him. It does relieve the stress on the amp in that instead of 1 amp providing bass to 2 speakers, 1 amp provides bass to 1 speaker only.
But, this is a class-A amp - it always runs 100% bias & it's well-known that class-A amps have zero headroom. That's just the physics of class-A topology.
His XA30.5 will still be a 70-80W/ch into the low impedance with a little more current. It will still limit the peak SPLs. It will surely give him music but not what the Ultima Salon 2's are capable of....
