Whizzer cones? Are you pulling our legs? I always associated whizzer cones with the know-nothing, 6x9 oval weird expensive speakers to throw in the back of your car market, not anything near audiophool quality.

Yes, and no. The whizzer was a kind of tweeter. But it also served the purpose (though I don't understand the mechanics) of decoupling the central section of the driver, allowing it to do a better job with the mids and highs. My understanding is that there /were/ some "good" drivers with whizzers, but I don't remember the manufacturers or models. Please do not equate "audiophile" with "audiophool". If nothing else, it's a rude insult to the people who have gotten high-quality sound reproduction to the point where it is.

To a first approximation, audiophools swear by Monster cables and gold-plated connectors, which audiophiles do not. -- The fashion in killing has an insouciant, flirty style this spring, with the flaunting of well-defined muscle, wrapped in flags. - Comment from an article on Antiwar.com (http://antiwar.com)

It's a common enough arrangement for subwoofers -- the term to search for is "servo". Proponents claim significantly lower distortion. -- Adam Sampson <ats(a)offog.org> <http://offog.org/> |
