To the OP, I have several pairs of SF speakers. You may want to look at the impedance curve. Many SF speakers have a very low dip in impedance at the low frequencies. The current output may be more important then the power output in watts.
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.
