Greetings,

Does impedance affect volume?

Two types of speakers. Bryston Middle T - 88 spl, 4 ohms / Monitor Audio GR 10 - 88 spl, 8 ohms

Will the same volume input give close/similar speaker volume output?

Thanks in advance….

Given that all else is the same and only the speaker impedance has changed the answer is Yes … assuming that the amp can supply the current needed.

The volume control adjusts the voltage gain of your amp. The output from your speaker is dependent on the power in …
Power = voltage squared / impedance

The yes above is to your first question … it effects the volume
