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.
Saying "91db" etc. is a bit vague. Take a look at this for a bit more detail: https://www.audioholics.com/loudspeaker-design/understanding-impedance-electrical-phase The Fritz Carbon 7 speakers are 88 db if memory serves but because of the nature of their impedance curve, I drive them with a 17wpc tube amp easily. |
