mikestanley Posted September 20, 2012 Share Posted September 20, 2012 I have a TH-SR-2 crossover that was used in some 2 way heresy commerial speakers. The coil has unsprung badly. Does anyone know the specs of the coil? Sugestions as to where to get a replacement? Thanks Mike Quote Link to comment Share on other sites More sharing options...

BEC Posted September 20, 2012 Share Posted September 20, 2012 The small round inductor should be a 500uH. Bob Crites Quote Link to comment Share on other sites More sharing options...

mikestanley Posted September 21, 2012 Author Share Posted September 21, 2012 Thank you for your certain answer. With all respect extended, I could ask a bit more about your answer. On this board, the coil in question in connected between contact 1 of the T2A and the positive terminal of the squawker. The is also a 3 micro farad capacitor between the positive and neg of the squawker. The coil is not physically small, standing nearly 1.5 inches tall and 1 diameter. The coil wire is quite heavy. I have not seen any schematic with this design. Have you seen this before? Regards, Mike Quote Link to comment Share on other sites More sharing options...
BEC Posted September 21, 2012 Share Posted September 21, 2012 The 500uH inductor and 3uF cap form a roll off on the squawker preventing it going as high as it would if allowed to roll off naturally. I am not sure why Klipsch did that since the squawker was not going to go much above 6khz even without that circuit. Perhaps it is there to match up a bunch of the THSRs and make them sound more alike by making them roll off at the same frequency. I have never seen an official Klipsch schematic for that crossover. I have made myself a hand drawn one from when I have worked on them before. Bob Crites Quote Link to comment Share on other sites More sharing options...
