Your 23wpc class A amplifier should have no problem driving a 10 ohm speaker. How loud the experience is dependent on room size and distance one sits from speakers.
Sensitivity question
I need a little help in trying to understand some basic concepts with speaker sensitivity. I understand that an 8 Ohm speaker rated at 88db (or less) can be a little hard to drive---and 6 Ohm can be harder. I get that----but on some small British speakers, they can be 86db but rated at 10 Ohm. So my question is this: is a 86db, 10 Ohm speaker hard to drive or not? Can I run them with a 23 wpc Class A amp? Thanks in advance.
