Agree with @ghdprentice . My Pass XA25 pure class A can drive my 91 db Dynaudio at 4 ohms. Room size will be a factor to consider however. Mine is 10x 19 .
How much power needed to drive 91db speakers?
Sonus Farber lists the sensitivity of my speakers at 91 db SPL@ 1 meter @4 ohms. They also say I should use 50-450 watts of power. My PS Audio amps pump out 500 watts @4ohms, so the max isn’t a problem, but if I switched to something 15-50 class A watts, would that be more than enough power?
Thanks in advance.
