(Outrageous Audio Equipment) recommends mirrors on the ceiling of my theater in order to provide a cleaner signal to the speakers via infrared transmission. (I think Fini will like this one...) Has anyone upgraded the power cord to their infrared transmitter? LOL On a more serious note, I wonder it they will ever incorporate something like that into loudspeaker systems? David ---------------- It's not infrared, it's radio! You would still need amplification to get the radio signal to drive a speaker. Just like FM. So at that point you can get back to the wire, power cord, etc. arguments.

I agree completely with the last two posts. I would not even try to palm myself off as a poetry critic but this was over the top. It was so sophomoric as to be laughable and I noticed I was not the only one laughing. (Of course, my opinion of the poetry is worth exactly what you are paying for it.) I also concur that it was the wrong venue. I think it is safe to say that when most people go to a Jazz club they expect to hear Jazz. The first thing everyone in the room noticed was that we could not hear the music because of her poetry, good bad or indifferent.

The really bad part, besides her performance, was that she ran everyone off so they did not get to enjoy the Jeff Hamilton Trio. Griffinator and I retreated back to the bar, where the bar tender had already turned off the sound, to wait out the onslaught. The wait was worth it. They were excellent! (They even had a CD worth paying for!) We were probably hunkered down in the back when the rest of you went to Rogers place. Sorry I missed that part but really enjoyed the great jazz, sans vocals. Griff was guessing that this was all a vanity act and she paid the house and band to put up with her. (She forgot to pay off the audience!) I couldnt come up with any better way to explain what we witnessed. If jazz is blue, then what color are the Blues?

'71 is correct.

I would like to add another round of heart felt Thank Yous to all of the following: The members of the Klipsch staff that spent a Saturday at work so we could wander around the lab and annoy them with questions. Klipsch management for supporting the gathering, both financially and allowing the employees evolved to make the arrangements. The folks at UA for welcoming us in and being so hospitable. The breakfast and free movies went above and beyond the call. (And the moves came in handy to many when the poetry lady showed up.) The Comfort Inn for giving us a good price on the rooms then letting a bunch of odd-ball types runaround the place with a stereo system cranked up to 118db spl! (I still dont believe that didnt cause complaints!) The Jazz Kitchen for feeding us such a wonderful meal and for booking the second act of the evening. (It was the Jeff Hamilton Trio and they were excellent!) My fellow attendees, without whom the weekend would not have been anywhere near as much fun! It was fantastic to meet you all!

Roy ---------------- Al K. responded to an inquiry I made about price and delivery on replacement networks for my Khorns within hours. He didnt know me from Adam, and still doesnt. That is a lot better response then I get from a lot of places that I have actually spent money at!

Why dont you have him show up next Saturday? (Or to the hotel Friday night.) Last I heard you will have about 75 Klipsch speaker owners there and I bet a bunch have Khorns. Ill be there, I own Khorns and would be happy to talk to him.

I added a center channel about 5 months ago. I had always been very skeptical about running a center mono channel. I thought it would destroy the stereo image. Boy was I wrong! I had decided to set up a surround sound system in my living room. (Using all Klipsch heritage speakers of course!) Well, I purchased a pair of used Heresys that were intended to be the rear flanking speakers. I dont have a surround processor yet so they were just sitting around collecting dust. One day I looked at them and thought about the section in Paul Wilbur Klipsch, The Life . . . The Legend about the advantages of a 3ed channel. At that point I had all the equipment I needed to hook up the center so if it didnt sound good all I had done was waste some time. (Of course, I dont consider playing around with my stereo a waste of time so I had nothing to loose!) Some system/room background: I have a long, narrow room about 25x14. Where I run a pair of Khorns along the short wall. (That is necessary do to the placement of the dinning room, hallways, windows and the patio door.) This put the sweet spot about 7 from the wall and that is a terrible place to put any furniture. So I built new tops for the bass cabinets and disconnected the HF cabinets. That way I could reduce the toe in on the HF cabinets and leave the bass bins in the corners where they need to be. My normal listing position is about 16 back from the wall the Khorns are on. With the mains on the short wall I really didnt think a center would be useful. For the signal to drive the center I took the tape out from the preamp and ran it to another preamp that I set to mono. Then I ran one channel of the mono preamp to one channel of a power amp. (Yes, I have too much equipment lying around!) I hooked up one of the Heresys and centered it between the Khorns. To my surprise it did not destroy the perception of stereo. I could still clearly pick things out on the left or right side of the stereo image. Material contained unequally in both channels seemed to move somewhat closer to the center but it still sounded very natural and easy to locate. It also seemed to make the image deeper. The other difference I noticed was that it increased the area of the room where you can appreciate the stereo image. As a rough guess I would say that went up by about 50%. I am now running a Cornwall II in the center and generally run it about 2 to 3 db below the mains. If $$$ were not an issue I would love to try a Belle or LaScala but that will have to wait. By all means, take the plunge!

Ok, now I see the error in my thinking. Once you have the bass coupled to the earth, by whatever means, it does not matter what the HF section is connected to since it all goes back to the earth, by whatever means. Therefore, there is no point in even trying to isolate the two. (What on the moving earth was I thinking?)

Wouldnt it be easier to disconnect the HF cabinet from the base and mount it on to the wall? Or am I missing something?

Thanks

Larry, I thought I had signed up for the trip but I don't see the members only forum. Thanks for telling me where to look. Maybe they don't want me there! (Or maybe Trey hasn't updated the list since I emailed him.)

Trey, Do you really moderate this forum twice? Where is the "MEMBERS ONLY" section for people attending the June 12, 2004 Forum Member Meeting? I cant find it. Thanks

I thought i had to take out the whole horn assembly. ---------------- Congratulations! You learned the difference between the horn and the driver! I was not able to find the thread that I saw earlier but I did find another one with pictures. It is at http://www3.sympatico.ca/bonaz/Klipsch/K77-diaphram/K77-diaphram.htm. He is replacing the diaphragm in a tweeter not the squawker but the procedure is similar. The good news is that the voice coil and the leads to it are not as fragile in the squawker as they are in the tweeter. (Thats why the tweeter usually goes not the squawker.) I think the squawker diaphragm is soldered in so you will also need a soldering iron. As mentioned earlier you should get a hold of Bob Crites (bcrites@cswnet.com and BEC on this forum) he has replacements. (I am also surprised he has not responded. Maybe someone should do a welfare check on him!) I also found this link http://www.speakerrepair.com/ocsdiaphragms.html as a source for replacements. Good Luck!

It looks like you got a post in while I was off looking for the diaphragm replacement instructions. I would agree that if you put a good driver in and it worked then you have a bad diaphragm.

Yes you should see some relatively low resistance value across a working diaphragm. (Not necessarily the impedance of the driver but explaining that difference is a long story and not needed here.) If you measured an open circuit (infinite resistance also known as a broken wire) then there is a problem with the diaphragm. Given that the squawker is broken narrowing the problem to the diaphragm not a bad thing. The diaphragm is the cheapest part to replace. Since you apparently have an ohmmeter and seem to know how to use it you are probably qualified to change out a diaphragm. I seem to remember a post some ware around here where someone had written up some very good instructions on diaphragm replacement. At this point I cant find the post. If I am not mistaken it was William F. Gil McDermott that did the write up in response to someone that had to change out a tweeter diaphragm. (But I am old and it is late and I could very well be wrong about the author, I know I saw the write up!) At any rate, if you have some mechanical skills, like being able to remove and replace some nuts that hold the driver together, you should be able to complete the repairs without much difficulty. If no one else has located the previously mentioned write up I will look for it again tomorrow. Ricktate is correct about them being tough puppies. It is very strange that a working diaphragm would give up the ghost overnight for no reason. Most electrical transients would take out the tweeter not the squawker.

Gee, I thought I suggested he test it.

The most fragile part of the squawker is the voice coil on the diaphragm. That is the coil of wire that sits inside the permanent magnet. When the power amp runs a current through the wire, it creates a magnetic field. This field reacts with the permanent magnet and causes the wire, and the diaphragm that it is wrapped around, to move. That diaphragm movement forces air down the horn and the result is the sound that you normally hear. That wire is very thin and most likely has burned up so no current can flow. That means no sound. If you have an ohmmeter and know how to use it you should be able to remove the leads from the squawker and test the terminals for continuity. If the meter shows an open then you need a new diaphragm. If the driver has continuity make sure wires to it have not come loose. The next possibility is the crossover network but they very rarely go bad. Did anything unusual happen prior to the squawker going south? Klipsch sells replacement diaphragms along with some people that regularly have them available over ebay. Good luck

They just played Black Sabbath's War Pigs and I was able to compare it to the CD. They are defiantly using a LOT of compression. The frequency range sounded ok but the dynamics are gone.

I own and use a Behringer Ultracurve Pro along with the ECM8000 mike to equalize for room conditions and I it works very well. I highly recommend it!
