Thanks again for the tip! This photo is indicative of the damage inflicted upon these innocent beauties. A couple more scratches, and that's it!

Four hours of driving for my new "B" networks, and these babies sound awesome! The cabinets are actually in very good shape. The faces have been painted , but only a slim shade from the original factory black. The only real scratches are on one long side of each of the speakers. There are still metal "feet" on one of the short sides, but no protection was used on the long side. There is also subtle marring where someone pried off the emblems, and turned them 90 degrees, but didn't re-install them in a manner that covered the old nail holes. All the corners are square and crisp, and the cabinets look like they have never been exposed to daylight. Other than my re-finished Shorhorns, these are the cleanest cabinets I own. The labels read C.D.15-FB. Cornwall. Decorator. 15" K-33-J (looks NEW). Fir? Black. (Flat Black?) It looks to be the same paint as my '73 La Scala type K-447's that have woofer access from the TOP. It turns out that I had met the seller before. He was the brewer in a small town pub in Oregon, 2 miles down the road from my sister's house. He purchased these from the original owner who had them built into his retirement house in Hood River. When the man I bought them from brought them to his home, he (and his wife) decided that they were too damn big. Just my luck. Now I guess I need another amp to play with. This addiction is giving a new meaning to the term "home stereo" for me. The modified Khorns are in the living room, the Shorthorns are in the dining room, and I have La Scalas running in Center (mono?) with one each in the TV/Guest room and kitchen. I believe I will leave that as is, and add the Cornwalls in the TV room with the La Scala Center as the beginning of a HT setup. Thanks for the tip about these wonderful '67 vertical Cornwalls from the year of my birth. Chris

Tom, Was your grandfather a barber? I remember sitting in the barber chair as a kid, looking in the mirror, and seeing a "regular" clock. Of course it was the reflection of a clock like you have described. Just curious.

Dave, I enjoy the wealth of information found at www.hifilit.com. The following page contains info about 15-WK woofers: http://www.hifilit.com/hifilit/Electro-Voice/119-5.jpg Let me know if you want to "borrow" a Jensen P15LL or University C15W as a temporary arrangement. If you wanted to pay shipping both ways, and were willing to return the "loaner" upon demand, I would be happy to send one to you. Shipping could be expensive as I live in Oregon. Give it some thought. Chris

One of us should open a Bose Boutique that would allow the "enlightened ones" to trade in their worthless Klipsch Heritage speakers. We could even offer to "dispose" of the outdated and unpopular Klipsch dinosaurs upon delivery of a new Bose system if they weren't up for bringing the trade-ins to us. Maybe we could set up a chain of boutiques across the country to better serve the people! Problem is, I guess, that people with good Klipsch speakers will always know what they have and will continue to persuade listeners without speaking a single word. Chris

I believe this is the bastard of which you speak. Patent # 4,138,594. It mentions a natural cut-off of close to 67 Hz, using a 15" K-33-E. Also mentions crossing over to a K-55-V at 400 Hz., and to a K-77 at 6000 Hz. PWK goes on to mention 108 dB SPL output at 1 meter with 1 watt, and 200 peak watts input capacity.

Thanks Guy, How about the AA's?

The cannibals only got the hearts, the networks. Actually, I've e-mailed the buyer of the networks, and he seems amenable to selling them after he has done some research with them. So for now, I will consider them to be "still" alive. Can anyone identify a problem with me running them with AA networks for the time being? I expect that I will lose something between 500 Hz and 600 Hz, but would I harm anything? I also have a line on some other "B" networks that I could buy this weekend. Could I harm anything by using these other "B" networks of a different vintage? Pardon my ignorance, and thanks for your help. Chris

Bob Crites, I see you got the networks. I got everything else, and would like very much to keep these units complete. I have another pair of B networks I would be happy to trade if that would be of interest. I would also be happy to buy them outright. Thanks for any consideration you may give to these Cornwalls. I'll check back in the morning. Chris

Dave, I have a University "Shorthorn" that came with C15W woofer, T-30 mid driver with Cobreflex horn, and HF-206 tweeter with T-60 driver. The Cobreflex doesn't mate well to the motorboard, and the T-30 isn't my favorite driver, but it is favorably comparable to my Klipsch Shorties. Food for thought.

Dave, Jensen P15LL or University C15W would also sound damn good. They are also 4 Ohm woofers, and I believe the Jensens (like a Stephens 103LX2) would be period correct. Actually, I guess I don't know when Klipsch stopped using Jensen woofers. I have heard though, that PWK wanted to use University woofers but couldn't make the deal. Rumor? Best of luck. Chris

Dave, Sorry to hear it's the woofer. Maybe someone here can help. I believe that the EV15WK was 8 Ohm, and these Stephens Tru-Sonics are 16 Ohms. That's why I was asking about the networks. If they were the same, I might try some K-33-E's in mine, and expect you would have good results with them as well. The crossover type is listed on the speaker labels, and stamped into the metal plate on the front of the base of the network. K-1000-5000 is ink printed before the stampings on the plate. These crossovers are "handwound". Is that what you meant by "conventional"? Chris

Dave, When you're inside, please take pictures of your crossovers. I am curious. My Shorthorns have K-1000-5000 crossovers, but I have 16 Ohm woofers. These crossovers are W5(S?)-22. Thanks, Chris

Dave, Congrats on the addition to your family. If you remove the side grills, there should be 6 screws (3 per side) that come from the rear to hold on the front frame and grill. Once you remove the front frame and grill, there are a number of screws (maybe 12) from the front holding the motorboard to the cabinet. Be careful when you remove the motorboard as the wire from the binding posts to the crossover is rather short. I think the "college" method of identifying your blown speaker is just fine. If you have a multi-meter, you could check the DCR on all components. Some people use a battery to test some drivers. Hopefully someone more technically minded will speak up. Enjoy your project. Chris

What is the difference between eating cow, horse, chicken, pig, dog, cat, fish, snake, soylent green, except for the taste? Someone's notion of what should be a pet compared to what should be food? What is the difference between shooting a cat for harming a child and shooting a racoon for eating your pet's food?

With an easy modification to the top section, the Klipschorn horn mouth could be as tall as the overall cabinet. The mid horn and tweeter would nestle between the rising halves of the basshorn. Different look for sure. Better low end? Thanks to everyone for their interest and participation.

If you scaled up the original twin driver dimensions for 15" woofers, the basshorn front panel would be close to 24" x 48". If the top of the basshorn were as depicted in Figure 1, you could place two Altec 511B's on top, and have room for 2 T-35's mounted horizontally or vertically. Not too big, maybe big enough. Any guidelines for what kind of performance might be expected? With all twin drivers, would any appreciable differences need to be made in the networks? Thanks, Chris

Your Subwoofer is smaller than your Klipschorn basshorn. It's all about compromise. I wonder what the price point of drivers VS. labor/plywood was. Note: the back chamber volume is also much greater in this early version.

I was hoping it could go lower.....

Here is a picture of a ready to cut paper model. Click, print, cut, fold, glue, and enjoy. You will notice one side panel shows twin woofers, a configuration I would like to learn more about. Chris

Here is a shorter link: http://www.audioannals.com/bio-k-l.htm Scroll down to Klipsch, and you will find several patents. The patent # for the basshorn is 2,373,692. I think you still have to download the TIFF viewer. The other patents are of interest as well.

Dave, Shorthorn model S, Birch, Raw. 15" woofer. Mine are # 993 & 994, inspected and tested on December 14, 1959! Being only 10 cabinets apart, they may have the same components: K-77 with silver lenses University SAHF with K-1000 horn Stephens Tru-Sonic 15" 103LX Can't wait to see it! Chris

Tom, This is from where I printed the patent documents. Page 1 is all you need for a paper model. Have fun! Sorry I don't know how to post as a link. http://patimg2.uspto.gov/.piw?docid=US002373692&PageNum=1&IDKey=48C7CC5389AE&HomeUrl=http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1%2526Sect2=HITOFF%2526d=PALL%2526p=1%2526u=/netahtml/srchnum.htm%2526r=1%2526f=G%2526l=50%2526s1=2373692.WKU.%2526OS=PN/2373692%2526RS=PN/2373692

This was submitted as Figure 8 of the patent. It is an alternate form of construction for "theater applications" with twice the power handling. I REALLY want to know what could be expected of such construction, and how the sonic signature could be affected. This method of construction seems much simpler than the Khorn, and the dimension/appearance is the same as the regular version. Any thoughts people?

Tom, I'd like to get around to a better model, as this one is slightly warped, and the front panel is slightly out of proportion to the rest. Any heavy pen you see is my attempt at sizing a 15" woofer in the drawing, and the top panel (showing the woofer) is a horizontal section that shows the woofer for clarity. Not meant to be misleading. Last week I started Google searching the various patent numbers on my speakers (I get bored easily) and found some fascinating things. I was able to print the April 17, 1945 Klipschorn patent. No dimensions are given except for front panel, front to corner, and front to intersection of the planes that make up the panels between the room walls and the horn's interior. The rest could probably be scaled fairly well, and the drawings are quite informative. With a combination of printer and camera, I was able to size and print copies of the patent drawings and tape them together into the model. I will look for the link to the patents, and also post an alternate method of construction included in this patent document for your review. Chris
