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.

I think that evaluating specs is an exercise in futility. I had an integrated specced at 300w @8ohm and then moved up to separates with an identically specced amp. The separate amp must be making twice the actual power of the identically specced integrated. Get some gear into your room and trust your ears. I don't trust the measured specs.
