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.

^Thank you. Appreciate the feedback.

Simply curious. How might this sound? Would like to compare--but don't want to destroy anything by doing something stupid. Is this in-series, or parallel? Seems like series. I'm no electronics expert, by any stretch--just a music lover. Have been trying to educate myself--but I still don't understand it. Found these diagrams and they got me to thinking something like this might be possible...

I have run this question past two very knowledgeable forum members/amp builders, and cannot resist the temptation to post it at-large, in the hopes that someone may have relevant experience and/or knowledge. This may be a crazy idea, ... but, in the spirit of exploration, here goes: •What happens when the two channels from a stereo amp--each carrying identical inputs--are run in series (as a single signal)? For instance, are the Ohms additive? Do a pair of 4 Ohm outputs combine into a usable 8 Ohms? What is the worst that can happen? For clarification, please see attached picture...
