Guest sbalfour Posted February 11, 2007 Report Share Posted February 11, 2007 I've got a collection of fried egg tweeters for the Advent Large,New Advent, and Smaller Advent. Most measure 3.1-3.3ohm DCR. Buta few measure 4.0-4.1 DCR. Nothing in-between. The ones thatmeasure 4+ have the same inductance (~.43mH) and capacitance readings,within a few percent. They have about the same impedance responseas the ones that measure 3.x, if one raises the graph a little tocorrespond to the one ohm difference. To my ears they sound the sameas the others. The only thing I can think that would do that, isthat their winding is a finer gauge wire, but otherwise the coilwould have the same shape and number of turns. Are the 4+ ohm tweeters some earlier revision? I've seen a description of "rev. 1"in this forum; is that where the 4 ohm tweeters belonged?

Guest harley Posted March 8, 2007 Report Share Posted March 8, 2007 i don't know what the fried egg revisions are, but i have a pair Jan. 1974 tweeters that read @ 4.0 ohms and a pair of 1976 tweeters that read 2.8 ohms.i've been curious about the difference in DCR, but don't really know what it means...anyone?the woofers appear to be pretty consistent @ ~ 4.5 ohms.

That expression was originally given to the excellent 1-3/8-inch AR-3 tweeter since it looked just like a "sunny-side-up" fried egg in a frying pan. Some people might get the Advent and AR tweeters confused.http://www.classicspeakerpages.net/dc/user_files/2124.jpgAcoustic Research AR-3 1-3/8-inch "Fried-Egg Tweeter."--Tom Tyson (10Mar07) Link to comment Share on other sites More sharing options...
