TP143, Agreed the subwoofer suggestion from cfelliot. Don't mess with it unless it is blown. I too have 1980 vintage Heresy I HBR's (103U425/426), and blew my woofer out about 11 years ago. I just replaced the K-22-R with a factory Kilpsch K-24-E replacement. Sounded fine afterwards. However, today I just performed the crossover repair/upgrade from Crites for my E-Series network, and WOW, what an amazing difference! After 31+ years, I had forgotten just how beautiful they sounded...and now with the new Sonicap caps, the speakers have once again come alive! Just to be fair (and as mentioned above,) previous mods included replacing both woofers, and the "plumber's caulk wrap" to the tweeter and squawker horns. Today, along with the Crites crossover repair kit, I replaced the horn-to-driver gasket with Crite's replacement, added weather-seal strips to the back case, cleaned all electrical connections with DeoxIT, and replaced the 8 back cover screws with slight larger and longer stainless steel screws (which I countersunk into the back cover. Otherwise, the Heresy's are stock...and sound fantastic coupled to my 1980 Sansui G-5700 receiver (supplemented with a Klipsch KSW-200 subwoofer on the lower end.) Can't recommend the Crites crossover repair kit more! Best bang for the buck.

Had the same bad hum problem in my 10 year old PSW-200. Tried the cheater plug and relocating the power cord to a different outlet, to no avail. Then I found the source of the hum when I was moving the SW's power cord around. The hum is being induced by a transformer that powers an older Terk AM/FM powered antenna! When I relocated the small transformer to the other side of the room, the hum disappeared. Woo-hoo. No need for any cheater plugs anymore! Hope this helps.

djk, You mentioned in your recent reply to me that the K-24's will not sound like the K-22's that I'm replacing. Could you comment a little further? How WILL they sound? Bad? Better? Or just different? Appreciate your thoughts. Brad (with two new K-24-K's on order...)

Gil, Thanks! I got to RS over the weekend, bought me a spiffy new digital multi-meter and made the tests as you suggested. Yup...blown woofer! I had no tone on the continuity test, and the resistance was well over 1 M Ohms and climbing...never did really stop. The other woofer checked out fine...got the tone, and got about 6.9 Ohms. So...I've spoken to Matt W. there at Klipsch Customer Service and he said the new Heresy II K-24-K woofer would work in my 21 year old Heresy I just fine. He also asked who gave me the suggestion from the BB...and I told him it was you. He said "your the man"! I found your instructions spot on. I've never had a multi-meter since my concentration back in school was ME, not EE (wrenches yes...multi-meter, no). However, that term paper I wrote about proper speaker placement (using the '80 Klipsch Audio Papers as a formal reference) for my one and only EE course was a help...I'm sure. Hell, I don't even believe in electrons! Thanks for your help... ------------------ Brad

Folks, Think I may have a blown woofer in one of my 21 year old Heresy I's. But how can I test to make sure it is indeed the K-22-R woofer that's shot, and not a component of the cross-over network? The speaker is an HBR, U-dated (1980), and has served me well for these past years. Would Klipsch's replacement woofer for the Heresy II (the K-24-K) be a good swap? Would I have to swap both woofers from both of my Heresy's so that the sound is balanced? Any other mods while I have it (them) apart? Thanks in advance. ------------------ Brad
