Ever bought inefficient speakers 4 this reason?

Has anyone ever bought less efficient speakers so they would have more control over the volume on the preamp?

I can only use about 1/3 of the potential volume adjustments because by the time I have the preamp volume pot set to 10 o clock it's getting too loud to enjoy.

I was wondering if less efficient speakers would give more control?
Assuming you like the speakers you have, I think the issue could be much more cost-effectively addressed by having a technician make a minor modification (changing a resistor or two) in either your preamp or amp. You might contact the manufacturers and see what they suggest.

I would go this route first.
