Duke above did a great job of explaining the factors of a speaker of lower effiency vs. one with a higher one. One other factor to consider is the nature of the load, i.e. the impedance vs. frequency curve. If you have a relatively high voltage sensitivity but a difficult load (one with low impedance and/or high phase angles), an amplifier with a high output impedance could have as much trouble driving that speaker as it could driving a speaker with a lower voltage sensitivity and a higher impedance load. Also, in some cases, your amp will drive the load to satisfying sound levels but its interaction with the load can significantly alter the tonal balance of the speaker.
High vs. Low Efficiency Speakers
Are there benefits / disadvantages to either?
I listen primarily to classical and prefer tube amps, does this lead me toward one speaker over another?
Lastly, I try to keep the music at a fairly low volume -- need to protect the hearing!
Thanks in advance and Happy New Year.
