SilverSport Posted February 27, 2005 Share Posted February 27, 2005 I have a set of Heresys from 1978...on 2 channel music when I turn the balance to one side, it sounds a bit hollow or different than the other...is there an easy way to tell if the horn midrange is blown??? I hear sound from both tweeters, both woofers but one side sounds a bit hollow...sorry, I don't know any other way to describe it...canging the speaker wires around (so left becomes right and visa versa) didn't really "fix" the problem... Any help will be appreciated. Bill Quote Link to comment Share on other sites More sharing options...
edwinr Posted February 27, 2005 Share Posted February 27, 2005 Can you put your ear right up to the drivers? But that hollow sound seems to point to the mid horn. If you pull the driver out and check everything is connected first - maybe you have a bad solder joint or something. Is Gil online? Perhaps he he has a better idea about what's going on.

SilverSport Posted February 27, 2005 Author Share Posted February 27, 2005 edwinr: I am trying that but not much help...I will try different CDs to see if I can get a better handle on this...the thing is that it sounds GOOD...I just don't know if the sound I am getting is the woofer and the tweeter doing all the work or that is how the CD was recorded...I had suspected this with other recordings as well...I even tried to listen to the same CD through my other set of Heresys but that is a processor/amp for HT (even though I was using stereo/bypass) and of course, it sounds different but still I can't tell for sure if the Horn is blown or what. Thanks for any help. Bill Quote Link to comment Share on other sites More sharing options...
WMcD Posted February 27, 2005 Share Posted February 27, 2005 I've always suggested using the tube from a paper towel roll as an improvised stethoscope. It will make you look very silly, so do this while no one is around. If you have a receiver where you can produce noise by setting it between stations, that might make the investigation easier. Most test CD's have pink noise and you could use that too. Gil Quote Link to comment Share on other sites More sharing options...
edwinr Posted February 27, 2005 Share Posted February 27, 2005 I was playing some Beethoven last night, Symphony No. 2, adagio, the left Klipschorn sounded like it was distorting slightly mainly in the right channel. I switched speaker leads and there was some distortion from the other channel but I could still hear it through the right. I listened through headphones and I realised that the distortion I was hearing was in the recording. The headphones could only just highlight the distortion. Through the Klipschorns though, I could hear the distortion as clear as a bell. Quote Link to comment Share on other sites More sharing options...
SilverSport Posted February 27, 2005 Author Share Posted February 27, 2005 edwinr, Gil: All right...I am now listening to some Coldplay-A Rush Of Blood To The Head...The Scientist and Clockers...it sounds GREAT...I can SEE the woofers vibrating and I can hear sound...both tweeters sound as they should...I get no feeling of vibration from either Horn midrange (K-55V) but with this CD, I can hear good sound from both sides and not that same hollow sound...the CD I was listening to was Liz Phair...perhaps that is not up to the quality of recording the Coldplay is or perhaps this is just as it is intended and certain instruments and vocal characteristics are DESIGNED to go to each speaker...

SilverSport Posted February 27, 2005 Author Share Posted February 27, 2005 I'll give that a try! Bill Quote Link to comment Share on other sites More sharing options...
SilverSport Posted February 27, 2005 Author Share Posted February 27, 2005 Okay, edwinr, Gil, everyone...I gave the paper towel horn a try...it does not seem like I am getting any sound out of the K-55V on one speaker...the woofer and tweeter do such a fine job that I only suspected this on some music but listening to me 2nd set of Heresys and then trying these back again, I believe the horn is out...what is the next step...they look perfect, do I need to buy something for them, or buy all new horns??? Yiikes! They have the greay crinkle finish magnet/covers on the back with Klipsch K-55V stamped in purple on them and appear to be metal horns...Alnico??? How much should I expect to pay for the horns...Do I have (should) to buy them in pairs? Thanks, Bill Quote Link to comment Share on other sites More sharing options...
WMcD Posted February 27, 2005 Share Posted February 27, 2005 No, you probably just have to have the driver sent out for a new diaphragm. It unscrews off. A lot of people here go to BEC. Someone else can give you the contact info. Gil Quote Link to comment Share on other sites More sharing options...
SilverSport Posted February 27, 2005 Author Share Posted February 27, 2005 I have sent an email to BEC...thanks everyone. Bill Quote Link to comment Share on other sites More sharing options...
edwinr Posted February 27, 2005 Share Posted February 27, 2005 A pleasure, Bill. Let us know how you get on with the new driver. Quote Link to comment Share on other sites More sharing options...

dodger Posted February 27, 2005 Share Posted February 27, 2005 On a good number of heresys, the wires connect via a spring opening rather than solder. I have seen cases where the wire was pushed in too far only a little metal touching then vibrating enough so that the wire moves and dis-engages or moves from vibration to a completely shielded portion. A second thought is loosening away from the Crossover. Try switching leads from your Amplifier and see if the problem moves. If so it can be a quirk of the amplifier. There should be red on one side of the mid-range- a 1/4" or so brush stroke of red. Some of the mid drivers were made by Atlas - model PD-4V and the spring loaded wire inserts run front to back. Those had Alnico magnets, 16 ohm drivers. Hope this helps, dodger Quote Link to comment Share on other sites More sharing options...
SilverSport Posted February 27, 2005 Author Share Posted February 27, 2005 dodger, everyone, It does...I will check this as well as some other things to run down and I'll let you all know what I find...Thanks for the help! Bill Quote Link to comment Share on other sites More sharing options...
ricktate Posted February 28, 2005 Share Posted February 28, 2005 Andy says those mid drivers are tough so i would check every wire..screw..connection first. Rick Quote Link to comment Share on other sites More sharing options...

Rick ---------------- With that I would strongly agree. I have one that came from Hopr - the Atlas with alnico magnet. Part of one of my alarm systems. Figure I'll deafen them. I've had it close to 30 years. Not a problem at all. dodger Quote Link to comment Share on other sites More sharing options...
SilverSport Posted February 28, 2005 Author Share Posted February 28, 2005 That makes me feel MUCH better! Since I am the 3rd owner of these speakers and the fact that they are from 1978 as well as they have been jostled about the last few months, going from house to house and room to room...I shall check EVERYTHING before parting with the green. Thanks! This place is great...Thanks everyone! Bill Quote Link to comment Share on other sites More sharing options...
SilverSport Posted February 28, 2005 Author Share Posted February 28, 2005 I am such an IDIOT! Instead of taking a deep breath and going over everything that could be causing my "blown horn" I just declared BLOWN HORN...today I am a bit calmer...I took the back off the offending speaker and luckier than I deserve to be a horn connection had come loose! Right now I am CRANKING Liz Phair and then that self same Coldplay but my speakers are 100%...unbelieveable for speakers that were made in 1978...when I was thinking of Junior Prom! (...and I HATE to think about that!... ;-) Anyway thanks to everyone here: dodger, Bob Crites(BEC,), edwinr, Gil, ricktate and Rdmarsiii (hope I didn't leave anyone out) for all the alternatives to what the problem might REALLY be... Horn Out??? Heresy I say! It was just operator error, I apologize to all of you and to Klipsch for doubting. Bill Quote Link to comment Share on other sites More sharing options...
dodger Posted February 28, 2005 Share Posted February 28, 2005 There are no apologies needed, nor do I and I'll bet the rest will agree, need to be thanked. That's what this Forum and Friends are for. Win dodger Quote Link to comment Share on other sites More sharing options...
