Mismatch what?Speakers impedance vary and will never match rating on the amp, and you will always have frequency variation due to mismatch.
One 8 ohm nominal speaker may have minimum that drops way down at one frequency to lets say 4 Ohms and may go way up at other frequency to let's say 12 Ohms. So which tap are you going to connect?
Other 4 ohm nominal speaker may have minimum that drops down at one frequency to let's say 3 Ohms and may go up at other frequency to let's say 30 Ohms). So which tap are you going to connect now?
Than some manufacturers mark tap as 8 ohms but in reality it is optimized for lets say 5 Ohms since they expect speakers to drop to below 8 Ohms?
Amp will controll better speakers from lower tap. With 6 ohms nominal speakers I would go with 4 Ohm tap.
There will be power loss no matter which one he chooses but is usually negligible from the SPL point of view.
