I know a lot has changed since this article was written– but I thought those still using tape might find it interesting (I did)...

@Chris A : Thank you for clearing this up. I really had no idea, and not knowing these details was causing some anxiety. Much better, now!

[ Bump... for Saturday morning crowd... any audio engineers willing comment? ] @moray james and @glens : Thank you both for the suggestions.

@Archguy: My comments (above) about using the the word "lambswool" were meant to poke fun at the marketing – and not the original post. (I, too, think the new "lambswool" screens look great). If they're only using the fibers from lambs, then fine. But if the fibers are simply wool, then call it that. There's nothing second rate about wool. And besides, a quality product's image can suffer if associated with exaggerations and hyperbole – that's the realm of hucksters – and I can't help but imagine where PWK would side on this.

I did something similar, and got good results using a linen blend. Linen can be sourced at any fabric store – but also quality art supply stores. 100% linen, and linen blended 80/20 with cotton can closely resemble the "lambswool" you mention, with the irregular striations caused by the variance of fibers and coloration. The blends tend to be lighter in color, closer to the color of "lambswool"... (Okay, I can't help myself here... "lambswool" ? Really? You're not using sheep? No sheep? Just the little lambs? I can see going to this trouble for socks and underwear – maybe – ?!) [ Aside: These are 80/20 blend. For those curious about the cabinet finish in the pictures – I've included a shot of the back label with the code ]

When driving speakers for extended distances (not just across town) does the orientation of the cabinets/components make any difference? I am about to drive a pair of Belles 900 miles – and I'm wondering if they should be standing upright, or laying on their backs, or sides? Anybody know about this? I read a post, on another forum, where I guy bought a pair of KLF-30s: https://audiokarma.org/forums/index.php?threads/klipsch-klf-30-advice-needed.665929/ They tested fine at the place of sale; but, after driving home, 3 of the 4 woofers had developed voice-coil-rub. Might be completely unrelated; but I thought I would ask.

I am interested; but, just to clarify, • are these being sold without crossovers? • and screens? (I realize the intent to go screen-less with that veneer; but, you mention magnets, and a pair of Heresy screens would be a factor... ) thanks. BTW – nice job. well done!

Also, location will help.

My collection of cassettes goes back 35+ years. About 5 years ago, I ran across them in deep storage and realized they contained a lot of music that I did not have in any other format (some of it rather dear to me). I bought a deck just to hear them... not knowing if they would even sound decent (or play?)... I was stunned by how good they sound. I listen to vinyl, CDs, FLAC... and now tapes, too. I don't know why; and I don't need to... but, a lot of these old cassettes sound GREAT (although few haven't aged well). I don't record – and can't imagine starting – but I'm not getting rid of my tapes.

PM sent.

I'm laughin' pretty hard! Great image!

These horns measure 30 inches diameter at the rim of the bell. And I'm no expert, but given the folded design--the 28" overall length would seem to be an effective length of 7 feet (?). These have come up for sale locally, and I'm wondering if they have potential for use in my barn/shop for music and radio. Can anyone tell me what frequency range this size and shape horn is suited for? They currently are without drivers. As an aside, I am also wondering if they've potential as part of a 2-way music system, atop a bass bin? If this is true, I might want to pursue that. I realize they are not one of the more modern horn designs--and they will never compete with state-of-the-art equipment; but, I like old stuff... and these are just cool. I like 'em. Thanks, for any advice.

This sounds like a great reason to buy the best one can afford in high-efficiency, low-distortion (fully-horn-loaded) speakers; --so much the better if you can find them at a discount. The impression I get, is that first-watt theory, and the almost direct-function existing between increased power and increased distortion, remains an almost arcane bit of info--when I would expect it to be much more commonly understood. I'm more than a little surprised the marketing folks at Klipsch don't make more of this as a selling point... High-quality sound at low volume levels is a game changer. Magic. [Edit] Oh, btw... Schu, nice purchase!

A thing of beauty is a joy forever (not to mention the music those will produce). Congratulations on what looks like a truly wonderful purchase! High point of my day, right here.

^Of course not... 'fluid dynamics' is far more accurate.

Seller has now put these on Ebay... down from 2k, now a starting bid of $999. Too damn far for me. Might be an opportunity for somebody... Ebay: https://www.ebay.com/itm/Klipsch-Klipschorn-Shorthorn-Corner-Speakers-Pair-from-1960/292616348377?hash=item44214b22d9:g:5k8AAOSwqbVbL6Qc

The good stuff never gets old...

^ Thank you, dtel. Ooops... didn't know about the other post: I'm gonna follow that thread--not this one. Can you delete my post? (Except for Shu's comment, of course!--that made me laugh). Thanks, endo

video: I won't be getting rid of my horns any time soon... But interesting. I know the approach has been around a while, but still... thought others might enjoy it. You might want to skip the first 15 minutes. --At 15 minutes: He starts running the sweeps --27 minutes: Freq. response comparison --32 minutes: The setup explained; and music played These may not be high fidelity--but makes one wonder about other applications...

@PrestonTom Yep. I think you missed it--I mentioned it in the first line of OP.

Perhaps worth mentioning: another method for cutting circular openings, (as long as they aren't too big)... It requires a drill press--and I realize not everybody has one--but for those who do, it might be an option to consider . I've used jig saws, routers and this drill press cutter--and this is my preferred method; especially when I want a clean, sharp edge (in natural veneer, with minimal to no tear-out). Your results may vary, depending on what the wood grain is doing. I have found the chisel tip of the cutter to leave a very nice, finished edge, similar to a quality forstner bit. This particular model cuts as large as about 4 3/8" inches (have used it in the past for oddball sized driver openings). A nice advantage: the cutter slides in its mount for tweaking to any size circle (within range, of course). The holes I've made with this are clean, and don't require any clean-up or sanding. I have been following this thread with an interest in modifying my own pair super heresy's. Many thanks to @ClaudeJ1 for sharing! ... I appreciate how much time and effort must have gone into figuring all of this out.

I want to hear a pair of these. Very curious about what's inside. Thought it might be nice to have the CL images posted here, for future reference.

On Nov. 10, 2017: This same reviewer posted a YouTube video, sincerely asking the question: Do high sensitivity speakers sound better at louder volumes than low sensitivity speakers played at the same volume, given adequate power... ?? (He wasn't just doing this for the camera; he actually did not know). Nobody gets it right all the time, but this is embarr•••ing. Moreover, his "favorite all-around speakers"? Magnapan .7s; with freq. response 45k–22kHz and sensitivity of 86dB/2.83v... ? Would these, then, be "audiophile", I wonder? (whatever that means). And why? "Who is this, that darkens counsel by words without knowledge?" –JOB 38; Anybody else see the irony?... His words about the Heresy are, uh... heretical.
