I have speakers that are 89spl efficient. My 30wpc primaluna with EL34 power tubes has no problem with sound level in a 20ftx 15ft room. I have drapes covering an 8x6 window, fabric furniture and carpet. The room size and what you have in it is a determing factor. With the power your system has you should be able to blow off your roof. 😆
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.
