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.

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 . |
in most cases a high quality 15-50 watt Class A amplifier will be enough to drive your speakers, it wil definitely be more efficient. Here's a snippet of power delivery and relationship: https://sw1xad.co.uk/technology_post/power-delivery-relationship-between-speakers-and-power-amplifiers/ |
@curiousjim ,I have a small Chinese made Pure Class A integrated amplifier that is based on the original Sugden A21..Puts out 15wpc.@8 ohms & can drive a 4 ohm speaker... |
Thank you! That is incredible generous of you and I will definitely keep it in mind.
