In Reply to: Compare the Stax F-81s to K-horns posted by plantsman on July 21, 2012 at 03:39:34:
all were down in the 70dB range for one watt. The Stax was 73dB for one watt in and the original Large Apogee was around 76 to 78dB efficiency. The AHL was down to below 71dB. It actually clipped 500 watt monoblocks during a demo without even being loud.
As a side note. Only two companies currently manufacture plasma tweeters, Lansche and Acapella Audio Arts.
For background, had the Stax, still have the Large Apogee and almost bought one of only four sets of AHL Tolteques that were ever imported into the USA. Unfortunately, the deal fell through due to various problems; shipping being one of them. The AHL came in eleven crates and weighed far over a ton, transportation would have run more than the agreed upon price. C'est la vie.
