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.
It is a combination of the voltage ease which 91dB @2.83V/1m is very easy load voltage wise but what is the electrical phase shift like? That can mean you'd need a high current amp. But yes plugging these parameters into this calculator -
Even if you sit 12ft away, you'd be getting to 96.7dB SPL peak at your seated position with the 50W maximum tube amp.
But why do you want the tube amp? You already have a competent power amplifier why cripple yourself? @curiousjim |
@curiousjim like I said you don't need a new amp but if you wanna dabble regardless that's your decision. Have fun :) |
