In Reply to: What qualifies as a high efficency speaker? posted by Travis on July 21, 2017 at 17:47:16:
Efficiency is more than a sensitivity rating. A 95dB sensitive speaker that sits between 8 and 12ohms full frequency response is a FAR easier speaker to drive than a 100dB sesitive speaker that dips to 2ohm from 20hz to 120hz. Most SET amplifiers will wheeze and puff on the latter speaker and will have zero issues with the former.
The LS-3/5a is only 82dB sensitive but sits 11-16 ohms. So a SET has no problem with these speakers. And while you are limited by volume the speakers can only handle a max of 50watts so yoy are limited by volume regardless of the amp you choose.
The title of the forum should probably be called high sensitive not high efficiency and then there should probably be levels like high senstive 92dB-96dB and very high sensitive 97-102dB and ultra high sensitive 103dB+
