WMcD Posted November 2, 2005 Share Posted November 2, 2005 I have not read of any K series. In any event, TS parameters first became used in about the late 1970s. That is when manufacturers first started publishing them. Therefore any literature published before then is not going to list TS parameters. I doubt very many manufacturers later provided the info for woofers which went out of production. BTW, can you give us any further information?

WMcD Posted November 3, 2005 Share Posted November 3, 2005 BTW, are you talking about EV speakers which were made for use in Klipsch products? At least some of them had a -K suffix. I have not seen any TS parameters on those, either. Gil Quote Link to comment Share on other sites More sharing options...
Malcolm Posted November 4, 2005 Share Posted November 4, 2005 Gil, Which EV manufactured Klipsch speakers had a K suffix? The ones I know of either had no suffix or an M (K55-M, K77-M), or just an EV part number. Doesn't the K suffix mean Klipsch? Quote Link to comment Share on other sites More sharing options...
Malcolm Posted November 4, 2005 Share Posted November 4, 2005 Ullman, Do you mean the 12WK and 15WK, the 12" and 15" woofers with 16 ohms nominal impedance and 3.2 ohm DC resistance produced by EV for Klipsch type horn enclosures? If so, they were produced before T/S parameters existed. AFAIK EV never published T/S parameters for them. Someone else might have, but I don't know who if anyone. If you have one, you can always measure it yourself. There are devices you can buy and hook up to your computer that will do most of the work for you. Or you can do it with releatively simple test equipment. Quote Link to comment Share on other sites More sharing options...
WMcD Posted November 4, 2005 Share Posted November 4, 2005 Malcolm, you beat me to it. The Georgian (Electo-Voice licensed K-Horn) plans show a 15 WK. Dope from Hope Vol 12, No. 5 list a 15 WK as being used in the K-Horn for a while. The Audio Magazine article on the Patrician show use of an 18 WK.

dragonfyr Posted November 4, 2005 Share Posted November 4, 2005 FYI If anyone is interested, here is one set of instructions and procedures for measuring and deriving the T/S parameters Measuring TS ParametersPDF.pdf Quote Link to comment Share on other sites More sharing options...
D-MAN Posted November 4, 2005 Share Posted November 4, 2005 Here is an except from the Vacuum Tube Vallwy article "Klipschorns - Out of the Corner Into the Limelight" which lays out the sequence of crossover and driver upgrades for the Khorn. A tip of the hat to Mr. McDermott, who originally posted the article! DM Quote Link to comment Share on other sites More sharing options...
