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.

No experience with Coda. An under the radar company that produces high current amplifiers you might find interesting. https://coda.cc/amplifiers

This is not a suggestion, just my experience.

According to Audio Science Review (I have no knowledge or reason not to trust his methods) my Carver 180 watt KT120 tube monos measured the most distortion he’s ever measured yet they sound absolutely stunning driving my very revealing Avalon Acoustics Eidolon speakers. Better presentation than my legendary sanctified Marantz 8B. 
As tube amps go the Carvers run cool and are easy on the power tubes. 
Good luck with your search.
