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.

It will work fine just will sound small and have limits on peak SPL. After all, you selected a small speaker and lower power. You picked your limitations.

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. 

Hoffman’s Iron Laws of Speaker Building

1) Bass Extension

2) Efficiency

3) Small Enclosure

The law is that you can only have two of these three attributes in speaker building.  Ideally, we would want all three, we want speakers with good bass, can play really loud, and are small.  Unfortunately, we cannot have all these.
