BEC Posted April 23, 2005 Share Posted April 23, 2005 And can you fix it if you have a bad one? I think I can start out the answer to that question. Bob Crites Quote Link to comment Share on other sites More sharing options...
BEC Posted April 23, 2005 Author Share Posted April 23, 2005 Seems this driver, made by Heppner (I have been told) was used for a brief time at least in the Cornwall. It is a 1.5 inch and is a "screw-on" driver. Quote Link to comment Share on other sites More sharing options...
BEC Posted April 23, 2005 Author Share Posted April 23, 2005 So, lets take it apart. Quote Link to comment Share on other sites More sharing options...
BEC Posted April 23, 2005 Author Share Posted April 23, 2005 Well, that diaphragm looks a lot like the one for the K-57-K and K-53-K except those have a plastic phase plug as part of the diaphragm assembly. The K-57H has a separate metal phase plug. Quote Link to comment Share on other sites More sharing options...
BEC Posted April 23, 2005 Author Share Posted April 23, 2005 Might as well try it. Never hurts to have a few parts left after putting things back together. I will just leave out the metal phase plug. Quote Link to comment Share on other sites More sharing options...
BEC Posted April 23, 2005 Author Share Posted April 23, 2005 Listened to it for awhile and it sounds good. Will have to put it on the spectrum analyzer when I get a chance and compare it to a trace I ran with the original diaphragm. So far, everything fits right and works.

jwc Posted April 23, 2005 Share Posted April 23, 2005 Bob, I don't think you can expect anyone to jump in on this one with expert advice. You could get lucky. jc Quote Link to comment Share on other sites More sharing options...
Deang Posted April 23, 2005 Share Posted April 23, 2005 I don't think Bob is looking for help JC, I think he's putting on a clinic. So what about the sound of that thing Bob, what's it sound like compared to the K-55-V - can you tell a difference? Quote Link to comment Share on other sites More sharing options...
BEC Posted April 23, 2005 Author Share Posted April 23, 2005 Dean, Fits right in with the other drivers. Sensitivity is almost exactly the same as the K-55M or K-55V. FR is right in between them. Bob Quote Link to comment Share on other sites More sharing options...
BS Button Posted April 23, 2005 Share Posted April 23, 2005 Hey, Those things look familiar. How do they compare to the PD-5V? Quote Link to comment Share on other sites More sharing options...
Deang Posted April 24, 2005 Share Posted April 24, 2005 The K-55-V is a PD-5VH - so Bob's saying the K-52 is right in there with it as well as the K-55-M. Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted April 24, 2005 Share Posted April 24, 2005 Bob, Do you know if the outfit that made those (Heppner ?) is still in business? Maybe they make a driver that could be used in place of the K55 sereis. Al K Quote Link to comment Share on other sites More sharing options...
BEC Posted April 24, 2005 Author Share Posted April 24, 2005 Al, I can't find any evidence that Heppner is still around in a brief google search I did awhile back. Now that I have seen the internals of one, I am pretty sure I could build them. I think that Klipsch sort of cloned these to make the later K-57-K and K-53-K and some others. During the (suspected) cloning process, they changed the screw-on front to a bolt-on for their later drivers. Bob Crites Quote Link to comment Share on other sites More sharing options...

Remember, Hepner died, and Klipsch bought the tooling and moved it to Hope, so with that mind, what you're saying makes a lot of sense. This is the reason I originally thought the K-52-H, and the K-52-K used later in the KLF series was the same driver. I'm still not convinced they aren't.

Someone might be able to verify that on the K-52-K. Bob Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted April 24, 2005 Share Posted April 24, 2005 Guys, I figure that outfit wasn't around any more! There is somebody that makes a driver that will go higher than the PD5 but I can't find them. It was mentioned to me by Shinall, but I couldn't find them. It's the one he uses and it looks like the K52! I don't want to contact Shinall again about it becasue I don't want to get involved with him. Al K.

Deang Posted April 24, 2005 Share Posted April 24, 2005 There's plenty of drivers that go higher, but do they go low enough? I'm drivered out, I can't imagine anything out there that's current production that I haven't looked at that's a suitable replacement for the K-55.

BEC Posted April 24, 2005 Author Share Posted April 24, 2005 Dean, Atlas must have heard you say that. They just notified me of a price increase on the PD-5VH. Bob Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted April 24, 2005 Share Posted April 24, 2005 Dean, I agree about the low end on the PD5. Shinall claimed this driver he uses would make it to 12 KHz. I don't have much respect for him though. He has no test equipment at all and I think he has a tin ear too! AL K. Quote Link to comment Share on other sites More sharing options...
Marvel Posted April 24, 2005 Share Posted April 24, 2005 I contacted Gary last Fall, to ask what componentshe used in his systems. This was the reply I received from him: I use several brands of speaker components in my speakers. I use the university T-35 tweeter,a university/EV mid range, and an Eminence woofer in my corner horns.The models AFS-1 and BFS-2 use the following drivers: Selenium ST-300 tweeter, Pro Systems mid range driver and a Pyle woofer.I build my own cross-over networks and the speaker cabinets.The cabinets are constructed from the finest quality plywood, they are built as strong and as sturdy as I know how to make them, I don't use any partical board like some other speaker builders I won't mention. I use wood screws, glue and wood cleats at the joints. The big KKS-1 corner horns, the AFS-2 and the BFS-2 have high frequency cabinets which detach from the bass sections. I use 1/4" machine bolts, nuts and lock washers to fasten these cabinet sections together. Quote Link to comment Share on other sites More sharing options...
