I just purchased a pair of Khorns from ebay -- one is 1954 and the other 1957. They have the Trusonic 103 LX2s in them and they are beasts. The mid and tweeter are from University. I would like to replace these but don't want to part with the Trusonics any time soon. I have a pair of K 33 Ps with the square magnets (from what year I do not know) and have them in the bass bins presently as the 103s are being serviced (some excellent people in Southern California) but prefer the Trusonics. The Klipsch people recommended keeping the crossovers stock but for replacing the caps. They mentioned as old as they are, Paul Klipsch probably hand wound the crossover coils. But they are designed to work with 16 ohm mids and tweeters and am not sure what I can or should update the mids/tweeters and still keep the crossovers. Sounds like another call to Klipsch might be good, but if anyone has some helpful information it would be appreciated. Kind regards, Dan

The best place to go is the Soniphase web site. They have several pictures of the SL-6 and the other offerings.

I want to commend Soniphase for providing a wonderful enclosure for the K 33s. It's called the SL-6, and for buying their tractrix horns (for the mid/high range driver) I was able to purchase plans for the enclosure for 200.00 and build them. Kevin Bartlett of Soniphase was most helpful with building tips and the results are brilliant, as they say across the pond. I have previously built a Jamboree and K-horn but the K33s shine far better in the SL-6 enclosures. For a real treat, I highly recommend providing a home for your K33s either by buying the enclosure or the plans for building them. I'm glad I made the investment and had the time to build them. I am also told they work well with the EVX 155, but these are hard to find.

I was able to obtain some plans for the original Jamboree bass bin from Soniphase (the design about 5-6 iterations ago) and took a few months to build it. I originally had Trusonic woofers installed but switched to K-33s from Kllipsch and they are much better suited to that enclosure than the Trusonics. I do have Trusonic 80Frs for midrange and the 5kt Trusonic tweeter mounted above the bass bin. I am thrilled with the result and plan to build a second Jamboree as I have two K-33 vintage Kkipsch woofers that are working quite well and ready for that home. My inspiration for this building came from this thread and I wish to thank everyone who has posted and kept this topic alive. Kind regards, Dan

Thanks Ski Bum. I replaced the Trusonic 150 FR with an EV 15 Wk and got a noticeable improvement in performance. These are kind of hard to find, so I don't think I will build a second enclosure unless one comes up. Tom, these Trusonics do sound old and tired, if that was your point. If you had something else in mind, I'm too stupid to figure it out. But I have bought a book from Amazon on speaker cabinets and hope to be a lot smarter in the future.

I have a question for Captain Bob or anyone: is there a way to lower the impedance of a speaker? I am new to all this and have a 8-ohm Trusonic 150 Fr I put in a corner horn and the results are not as good as hoped. The enclosure is not a stock Khorn but very much like it The speaker sounds a bit muffled and the bass is hard to find. I was wondering if the problem was with the impedance, of some other issue. This is my first post and if I sound like ignoramus it is because I am. Any advice would be most appreciated, and thanks in advance. Dan from Pasadena
