Hello, I wonder if you would be so kind as to provide me with the productions scans for Klipsch Music Reproducers # 242 and 1720 & 1721

Well, that was the problem, these things sound amazing like they are supposed to now. Thank you for everyone's help Here's a link to a video of them playing

Do you think the Klipsch Timeline PDF is a typo? Maybe they meant RP302? Also, I did find a problem in the original crossover, two of the spade lugs were slightly loose. I tightened them up and reinstalled the original driver and now it sounds like it's supposed to, bass and all. I am beginning to wonder if the bass dropping out probably was just a loose wire and not a crossover problem " The first three-way Klipschorn incorporated a Jensen RP203 tweeter. This tweeter came from the famous Jensen G-610 Triaxial 15" driver and required considerable negotiations with Jensen. It was not until mid-1952 that all Klipschorns were three-way. A two-way Klipschorn with response to 12Khz was generally adequate for program material up to that time. The University MID-T- 4401 replaced the Jensen unit as the tweeter of choice later in 1951. "

Ah your suspicions are correct Also, very helpful information confirming impedance on the woofer for me. Looks like 8 Ohm on tweet, 16 Ohm on Mid and 4 Ohm on woofer. Interesting combination Anyone able to decipher the finish code 413F? I read through the ones listed on the PDF and didn't find it Wonder what the chances are of finding a vintage Jensen 203 tweeter anywhere Thanks Robin

I say crossover upgrade project because that is what it was turned in, a project, ha! I rescued this single khorn in 2016 off Clist, brought it home and tried setting up a mono system with it. I sourced a couple mono tune amps, tried them and they sounded horrible. The 6V6 based tube amps sound sterile with not much base. I sourced a cool EL84 based mono tune amp (Madison Fielding Series 12)and it had moments where it sounded glorious, exactly what I was looking for, then the bass would drop out, almost like a bad connection. Ended up leaving it in the corner and not really doing anything with it until recently when I acquired my holy grail, a Lowther Music reproducer. Wanting to use this Madison Fielding amp I tested in on a Karlson I have kicking around and it works fine there. Ultimately, I took it in to a shop to be reconditioned and bought another amp ( Sherwood) to use on the Khorn. Bass was missing so i decided to finally remove the crossover and send it to Bob Crites for rebuild. Course he had me check the Ohms on the drivers and taht's where thing began to get squirrely. The tweete tested out at 4.2 which I thought to be low, The mid tested at 11.4 which confirms a 16Ohm Mid. The woofer tested at 2.6 which is also strange. So what I thought was going to be easy peasy now is getting a little more challenging. Now I have to disassemble the speaker and confirm drivers so I can get the correct crossover rebuilt, which is why this thread. This speaker is actually looking to be a true 1951 speaker, The serial number indicates it was probably the real 242nd Khorn ever built and it is in excellent condition so I think it deserves to have everything verified and I will use it to build a true mono hifi project around it, featuring a Klipschorn Sound Reproducer. Interesting name, sounds an awful lot like a Lowther Hegeman Music Reproducer of the same vintage. I think Lowther had about 400 of these delivered by them so Klispch would be catching up. I have done the research and have a lot of questions, for example, I wasn't able to confirm the finish and I'd also like to confirm what speaker components are used and the proper Ohms. I'd also like to confirm polarity for each component. The lamp cord used doesn't help. Seems all the terminals are marked 1 or 2 not - or +. The tweeter is an Electorvoice T35, with an Ohm reading of 4.2 whould that indicate 8 Ohm? The mid is a Univerity Model SAHF. It's labled 16 Ohm and tests at 11.4 so the is pretty straight forward The Woofer is a Jensen and I cma unfamiliar with it. It tests at 2.6 Hope you guys like pictures Thanks in advance for your help

"I also have a fully rebuilt M200t that I may add in for the top end and biamp them." Now we're cooking. Here's an old video when I was playing around with my CF-3s

I am sure your Stromberg Carlson sounds very nice. The OP was looking for suggestions so I shared my observations. I personally haven't had much success with SET amps and Klipsch speakers, just speaking from my experience. I think the Klipsch line is better suited to EL84 and KT88 push pull type tube amps. I had a Carver Cherry 260 with the KT 120 tubes in it. They sounded very nice on my hereseys and Cornwalls but I wasn't able to bi-amp them on the CF-3's. I had a buddy come over, TNRabbit, who is also Carver and Klipsch aficionado and listen to them with the Cherry 260 amps. I left him alone for about a half hour and while they did play loud he walked out of the room and wanted to know what happened to the mid range. He heard them on the Sunfire so he knew what to expect. I've also had a plethora of Carver amps and they sound nice but it's not about the loudness, but the quality of the sound. The Sunfire amp is a completely different sound which is why I suggest it. If you really want to hear what your CF3's sing. Try bi-amping or bi-wiring them. I think you will be surprised.

Hi Jesse!!

I don't think you will be very happy. I had those speakers for almost 20 years. I sold them last year. They really want power to open up. I have several 300b tube amps and they just didn't sound good on any of my Klipsch speakers. The hot set up I had for the CF3 was a Sunfire tube preamp and the 2 x 600 Signature amp. This amp will let you hook up both the current output and the voltage output with 300wpc each. I ran the current to the tweeters and the voltage output to the woofers and the sound was unbelievable, kind of a bi wire set up. When I didn't biwire or bi amp these speakers it seemed like the mi range was missing.

Nice pics everyone. Here's one I took the other day of my 300b amp, please pardon the dust.

I've had these in the closet long enough so I guess it's time to move them. I bought them new and they look good and work great. There is one water ring on one speaker but it's not very noticeable. These are the version 1's. When I bought them they didn't have the port tubes installed and they didn't have feet so had to buy some from parts express and only found 4 inch tubes. Based on the consecutive serial numbers they are the version 1's. I am looking for $700. I am in Fredericksburg Virginia and about 10 minutes off I 95 so it's pretty easy to get to my house. Local pick up only. Best way to reach me is email tinpanatmedotcom

I have a couple pair of Klipsch Heresy speakers that are collecting dust. If you are in the Washington DC area these are some nice classic heritage speakers. Pics are here: http://public.fotki.com/Tagginbac/stuff/page57.html pics begin on the page linked above and continue to the next page Light color HBR finish with the cane grills. They are a little knocked around but still look and sound very nice. One corner has a ding, one of the cane grills is coming undone, but still presents well. It's nice enough I didn't think they needed to be redone.Made in 1985, consecutive serial numbers$400 obo Dark color HBR finish but it looks like someone later added a nice walnut stain. They came out very nicely. There is one chip in the veneer, but you can't even see it unless it's pointed out. Made in 1985 $425 obo
