I regularly drive a pair of JBL 4349s (91dB) with either a Sugden A21 SE Signature (30W class-A solid state) an an AR i/50 (50W push-pull tube, class AB). No issues with either having plenty of power.
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.
