Lower distortion and better low level detail. FWIW: See the article below the importance of speaker efficiency. Mike http://www.lansingheritage.org/html/jbl/reference/technical/efficiency.htm |
Higher sensitivity is better as long as its not achieved by simply paralleling drivers, resulting in a lower impedance. Lower impedance causes amplifiers regardless of type, to make more distortion. If the speaker is low sensitivity, one common result is something called 'thermal compression' where the voice coils heat up with things like bass notes, causing the driver to be less efficient. This is quite audible and is why people with horn speakers often talk about how much more dynamic they are.

@ditusa , one would expect that some advancements have been made in the last --- 60 --- years. @atmasphere , I would think that the frequency effects of compression would be more worrying than a change in maximum output? Perhaps this is another case for active speakers. |
@deludedaudiophile Good point and one more problem to add to the list... If the speakers are inefficient, powering them really won't help the dynamic issue. You simply need greater efficiency to get around that. |
