tonygeno Posted March 1, 2005 Share Posted March 1, 2005 Just purchased a set of 1987 H IIs and one of the squawkers is DOA. What are my options for replacement? Thanks, Quote Link to comment Share on other sites More sharing options...
djk Posted March 1, 2005 Share Posted March 1, 2005 Before you call Klipsch service and they send you the correct part for about $30, swap the horn into the other cabinet to make sure its not the crossover or wireing. Quote Link to comment Share on other sites More sharing options...

jerohm Posted March 1, 2005 Share Posted March 1, 2005 In the worst case, you need to replace the diaphragm. They show up on eBay now and then, but should also be available from Klipsch. I guess the first thing you need to determine is if the driver is really bad, or it is a connection or crossover(unlikely) problem. Swapping it with the one in the other working speaker is probably a good start. If you remove the old diaphragm, and the voice coil is still that nice copper color, there may be hope to get it to work again. (looks like I was a little bit slow with my typing!)

tonygeno Posted March 1, 2005 Author Share Posted March 1, 2005 These are Heresy IIs. How do I get the squawker out of the box? The hole isn't big enough, and the front or back doesn't come off. I'm perplexed. Quote Link to comment Share on other sites More sharing options...
tonygeno Posted March 1, 2005 Author Share Posted March 1, 2005 Well, I disconnected the wires to the squawker and hooked it up directly to my amp at low volume using white noise, and low and behold the squawker plays. When I reattach to the crossover, it doesn't play. Any ideas as to what's up with this speaker? Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted March 1, 2005 Share Posted March 1, 2005 you have to take the woofer out. once it's out you can disconnect the wires and unscrew the driver from the back of the horn. Don't price the driver or the diaphragm from Klipsch, you'll faint. Bob Crites (forumname is BEC) gives a much better deal. he'll also replace it for you if you're not comfortable with the minor soldering and whatnot needed. He goes by bobcrites on ebay, usually has one or two on there. Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted March 1, 2005 Share Posted March 1, 2005 sounds like you've got a crossover problem. pull it out through the woofer hole and look it over carefully for broken wires, bad solder joints, etc. be sure to snag the model number of the crossover while you've got it out.

tonygeno Posted March 1, 2005 Author Share Posted March 1, 2005 I found the problem. The midrange cap has a break in one of the legs that's about 1/8" from the cap itself. I have attached a photo. Is this repairable, or do I need a new cap? Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted March 1, 2005 Share Posted March 1, 2005 you might be able to solder that, give it a try. if you can't, bend it around so you can read the values printed on it, get a new one. there's lots of places to get then, like www.partsexpress.com. you don't want to replace it with a cheap POS from ratshack or somewhere, you need a decent cap similar to it. There's a guy DeanG who posts here alot, he offers the service of rebuilding/upgrading the crossovers. many users report marked improvement in sound quality. That would pretty much eliminate further questions about the crossovers. Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted March 1, 2005 Share Posted March 1, 2005 hmpf, double post. Quote Link to comment Share on other sites More sharing options...
tonygeno Posted March 1, 2005 Author Share Posted March 1, 2005 I can't understand the values. What's written on the cap is: 2E155 and then below that: N Japan B605. I have no idea what that means. Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted March 1, 2005 Share Posted March 1, 2005 I'd guess it's a 2uf, but let me ping one of cap genius's here. All those all the characters on both sides? Quote Link to comment Share on other sites More sharing options...
tonygeno Posted March 1, 2005 Author Share Posted March 1, 2005 That's all that's written on the cap and it's written on one side only. Quote Link to comment Share on other sites More sharing options...
jerohm Posted March 1, 2005 Share Posted March 1, 2005 IF this is correct, it looks like they are all 1.5uF. Do all three have the same printing? (The cylindrical one should be the 68uF.) Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted March 1, 2005 Share Posted March 1, 2005 Iposted a request over in the two-channel forum, somebody will stop by before long. some of the guys from back East might have logged off already. Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted March 1, 2005 Share Posted March 1, 2005 jerohm is fast, take a look at that schematic he posted, I think he has it exactly right. The cap can be fairly low voltage, lots of crossover caps are 100V. Thanks, Jerohm. Quote Link to comment Share on other sites More sharing options...

BEC Posted March 1, 2005 Share Posted March 1, 2005 Might take a shot at trying to attach a wire to what's left of the cap lead or just go for something similar to this: http://www.partsexpress.com/pe/pshowdetl.cfm?&PartNumber=027-412 If it were me, I would probably go for an order of 6 of these and replace in both crossovers to keep everything sounding right.

tonygeno Posted March 1, 2005 Author Share Posted March 1, 2005 Thanks, guys. Any type of cap I should be getting? Film, mylar, tantulum, polypropolene? I appreciate the help! Quote Link to comment Share on other sites More sharing options...
