I apologize if this has been beaten to death already but I’ve never paid that much attention to power in my system. I have a pair of M700s driving bookshelves… so the Pre’s always at like the lowest tenth of what it can do.
But anyway, I am curious about upgrading my speakers in the next year or so. This Powerplay deal has me more curious about all the power numbers that I haven’t paid much attention to!
So if I understand correctly, when a speaker spec sheet reports 92dB efficiency this means that 1 watt gets me that 92db, and I would need 100watts to hit 112dB and 1000 watts to hit 132dB?
I guess this is where I get confused because realistically I never even listen to music at 92dB… but surely this doesn’t mean that I expend less than 1 watt per channel by listening to music below 92dB, does it?
Is there a general rule of thumb between what your amp power to speaker efficiency should be?
And also, what’s up with the impedance. If a speaker says “nominal impedance: compatible with 8 ohms” does that mean it is an ‘8ohm speaker?’
Thanks for taking the time to read!
