Yet for speakers there is an alternative to that school, and it doesn't hinge on brief demos of Accords vs Corollas to teams of amateur listeners in an office park. And they were playing. But according to head designer Roy Delgado, who began his career working closely alongside Paul Klipsch—and has now been with the company for 33 years—"the Klipschorn's low-frequency horn is the one thing that has changed the least. This shows the same information as a polar plot in what I feel is a more easily comprehensible manner. Enter the £12,000 La Scala AL5 you see here, which is pretty much the same supper, served on a smaller plate. But I remember seeing the distinct blue faceplate and huge meters of McIntosh gear in the room. Design and Quality: If you’re after full black speakers that are aesthetically pleasing and powerful, the Forte III will provide you with just that. Not being snarky here - I'm confident none of my customers would change a thing. ".... to deceive and confuse" ......... Oh please JA1, don't run for public office ........ We need you here at Stereophile :-) ....... ..don't do it at all. Impressive. Hmmm, popcorn ready, I'll be waiting for this answer myself! The veneer leaves are kept in order as they are delicately sliced from the timber and precisely arranged to provide a mirror image at the splice joint — like turning the pages of a book. There was a shop in Ferndale California, really beautiful all-wood construction, probably built in the early 1900's. The tweeters were remounted all the way in the back of the speaker right above the midrange compression driver to time align the mids and highs. exponential-horn. Paul Klipsch nailed the issue 70 years ago ... "What the world needs is a good 5-watt amplifier.". 'The benefits of horn loading have not changed.' I moved on to Sonus Faber when heard a 3d soundstage from Extremas that just moved me in a different way. First, though, I'll mention that according to the manufacturer, the new K-horn does not require corner placement. Most likely it will sound gorgeous, as well :-) .......... See my comments elsewhere..you're interpretation of the manual is completely incorrect. Klipsch is an Experience , nearly indescribable with words. Many of the tests used to test loudspeakers have baselines that are subjectively derived. Put another way, rendering this speaker flat in the amplitude domain is no guarantee that half a dozen key criteria - which are in effect why horns exist - would be improved, if even addressed. Well, amplifiers are cheap—we really don't need high efficiency in a loudspeaker system for the purpose of getting more horsepower output: We could just put more horsepower in from the amplifier. It has, however, been well-served by seeing speakers as transient energy devices, which is how music manifests. The first prototypes of the Rival had a flatter response in the bass. Klipsch only uses book-matched wood veneers for the Heritage series of speakers. Mark Henninger. Are you willing to share an example of a specific design choice you made that resulted in worse measurements and better sound? Here's the language from the manual: "The Klipschorn (AK6) has a fully enclosed low frequency horn and no longer has to be flush to the corner in order to operate properly. I've now wasted enough bandwidth on this subject. The compendium of papers in their original form includes never-before-seen issues, hand-written drafts, and supporting images and diagrams. Realistic sound reproduction, or certainly its approximation hinges on physics of which size, sensitivity and ease are core parameters, and I don't see any of those apply to the AR1 and its same-principle descendants. (Try DARKO KIH #25 "what do measurements really tell us"). I brought this up at Audio Asylum in a thread called "Those darn measurements" about 2 years ago. I still heard everything I didn't like about the amp, but it worked better with the Klipschorns than any thing else on hand to hook up to the horns. !....this is crazy. They were made in the USA by the hands of Paul Klipsch himself and everything we’ve done since then was because we started here. Some serious DSP and tri-amping would help this beast out immensely. One might safely say that recent interest in low-power tube amps has rekindled interest in those models; at the same time, the recent success of hi-fi/vinyl bars, themselves inspired by Japan's long-lived and similarly outfitted jazz cafes, has also rekindled interest in large, horn-loaded loudspeakers. You can build a far better speaker than a K-horn for relatively very little money......planars, like mine, horn speakers, dynamic drivers, etc. This speaker's potential has not yet been fully exploited. 450Hz, brown, Klipschorn AK6 - American Walnut. There's no denying the success Mr. Villchur's design spurred for years to come, in that regard certainly the future of loudspeakers, but what's the benchmark here? Better than 300B tubes. For the most part, the listener sees only a large, unblemished expanse of wood, beautifully veneered, but behind it is a front-firing 15" woofer loaded by an 8'-long exponential horn. Indeed, why go picking on someone who never really intended to play the VLF-play you so desire? I'll draw the curtain of charity over my experiences receiving, unpacking, and assembling the Klipschorn AK6s: On the day they arrived, I was the only one at home, and none of my able-bodied neighbors were available to help. KEF understands that and they know more about speaker design than anyone who writes here. It's not that I don't welcome improvements made to a design; my own speakers are exactly that of the Klipsch Belle. Moving fast forward: time alignment is solved by mounting the tweeter on top, aligned with the midrange horn. My guess: in this case, probably yes. Realism, as it applies to <50Hz, to my ears has to do with total ease at any SPL, as well as smoothness (an indication of low distortion), visceral impact and being fully enveloped. The authority on good design is sound, even as annoying as the human element has become of late. My reply was followed by a three-day lag in correspondence, after which came the disappointing news: "We're sorry: It won't work." -Fortunately others continue on, with excellent effect. We were chatting just after hearing a demo of an excellent, modestly priced loudspeaker. Regardless of the flaws, to me the one thing is that someone could drop serious money on this speaker and never know that their amp is not a great match for this new model. Each Compare: Meaningful distortion plots are difficult without access to an anechoic chamber, as I have explained in the past. After owning K-horns, owing Quad 63s seemed an ideal relief. Heritage Series Speakers. The same can be said of miniature coaxial speakers. The operating words here are ease, ultra-low distortion (for bass reproduction) - even at close to full chat, and room-filling envelopment. I began with the backs of the Klipschorn AK6s a short distance from the front wall—their front surfaces, measured at the centers of the cabinets, were a little more than 3' from that wall, and a little more than 8' apart from each other—and with the speakers slightly toed-in toward the center listening seat. The Khorns may run out of extension below 35-40Hz, which is what you're facing when dealing with a "only-so-big" 1/4 wave horn, but for what it does its 15" driver, horn-loaded at that, will have to move much less than a smaller direct radiating, say, 8" woofer to attain the same SPL at a given frequency. Based on over 40 years experience with the same set of K-Horns in many environments, here are a few other suggestions for maximum enjoyment of the Klipschorns (only after you have a correctly sized room and listening position): - Get the most massive, powerful quality subwoofer you can afford to fill your large room with silky 15Hz - 80Hz bliss. It just won't replace it, which along with not speculating about either is a key truth. That would stay true to Paul's desire for good acoustical matching while maintaining better wavefront propagation in the horn resulting in fewer internal reflections and the ragged response shown. Every Stereophile loudspeaker review includes the measured step response. Back in the mid-90's, I hung out with a man who installed custom audio systems, had bulk Van den Hul solid-core interconnect. Still a beautiful product with a solution in sight. The Beatles ........... About having that cake and wanting to eat it too. Klipsch has a rich heritage of emotion, power, and efficiency. All this talk of DSP and tri-amping to change the Khorn into something it is not just seems foolish to me. To be clear, by "classical" I mean not traditional but orthodox from an engineering standpoint: resonance-free enclosures, even, flat frequency response, uniform dispersion, etc. p.s. Sub-par test results, great sound, IF driven and set up right. If you feed poorly Who wouldn't want that; it's all for the good. I could design a passive crossover for luddites in my sleep, but alas... i was a subscriber from 1983-1999,went to 2 Stereophile shows(Santa Monica 1st & San Francisco) K-horn owners were always asking for a review,but JGH&J.A. I use Altec corner horns and the improvements in sound quality once I moved them to a long wall with full height smooth walls of 10 feet adjacent to each speaker was nothing short of Devine Intervention. A few British speaker makers still employ that lossy-jointed, thin (and damped) wall concept of cabinet design. He left the magazine's staff in 2003 and joined Monster Cable, working in marketing. Every Man Friend will think that You own the finest loudspeakers ever made, every person in your neighborhood will know that you own them and know when you sell them. I think JA's testing of the Rivals was pretty much spot on, and looked very much like my own tests. The constant power, uniform directivity philosophy, coupled with the standard approach to lowering resonance and hopefully distortion, has delivered many a nicely theoretical loudspeaker. Not a lot of bass, but everything else was right in place. The more classic Front Loaded Horns - again, non-DIY - could be the JTR Orbit Shifter LFU. If the rationale would have been so obvious to dismiss them for "every minute" of their prodigious +70 year lifetime based on their supposed shortcomings, I'm sure many would have had ample opportunity to do so. Many automatically assumes that when an all-horn setup (or any other big, high-SPL capable ditto, which typically ends up being horn-loaded anyway) can potentially challenge the structural integrity of a house/apartment, then that's its sole or most "profound" purpose. I see that fable often on audiophile chat sites "measures good sound bad, measures bad sound good". That's a subjective evaluation. The last thing we need here. First let me be clear..it's tough measuring a corner horn like this. The Dudley quote is mostly as half-baked or uninformed as everything else he wrote about loudspeakers. Problem seems to be 'quasi-knowledge' of some of the commentators :-) ......... Those measurements are not what you expect from a $15k speaker, good luck selling these Klipsch today at that price, back in the 50-60's maybe. Each Compare: 1066444. • While flat frequency response is preferable, it is not nearly as important as the ability to equalize the group delay and eliminate the phase distortions of a speaker. Another friend gave me a Marantz 8b. Mr. Villchur simply referred to measurements of his own design and invention implicating (in effect) a perceived sonic advantage, something I believe is quite dubious. Effort-less sound and effort-less dynamics ..... just like in real life :-) ......... ... there was an example posted to another site of a music clip with an apparent difference between peak and average levels of approximately 22dB. Color Name: AK6 Walnut 1 option from CDN$ 21,998.00 . There are plenty of them out there, new and used. As was made clear in the article via an extended quote, corner placement for the new K-horns is not required, according to the company. Where's the tone-bursts ? A RARE BEAST In addition to the legendary acoustics and impressive upgrades already included in the AK6, the Klipsch Museum of Audio History is proud to offer a limited production of one (1) pair of unique Museum Edition Klipschorns – Numbered AK6 ME-001 and AK6 ME-002 – with official documentation verifying their provenance. Thinking the time was right for a Klipschorn review—2006 was the 60th anniversary of its design—I got in touch with a Klipsch representative, who requested photos of my room and details of its size and construction style. XRT-20's, Yamaha NS-1000, ESS AMT 1B, The whole Klipsch Heritage line, Altec Valencia, EPI 1000 towers etc. No loudspeaker in audio history claims a richer heritage than the Klipsch Klipschorn tower loudspeaker. • A DSP'd, multi-amped KHorn would be mind blowing and further validate a truly great design that should be improved upon for future generations. I previously used an SVS SB16-Ultra with my Uccello's (derived from the Klipsch Belle), and shifting to a pair tapped horns has been bliss ever since. Basically it is like going to a small jazz club but the performer is a stereo rather than a jazz combo. The ceiling was two stories high, the floor-plan was open, about 30 feet wide by 50 feet deep. If you are some type of purist who wants to stay with obsolete technology, are you also willing to state that CRT screens and video tape are as good or better than Blu-rays and OLED? The impedance of a horn speaker depends greatly on the horn loading....it's not clear in the review text if the impedance was measured in room or in the driveway. I think Art and JA, and Mike Fremer in his recent impressions from listening at, was it darTZeel? Phew !!!! 1 option from CDN$ 21,998.00 . This observation is corroborated in the AK6's slim owner's manual, which states: "The Klipschorn (AK6) has a fully enclosed low frequency horn and no longer has to be flush to the corner in order to operate properly. And one of the best stereo demos I have ever heard in my life was from a pair of Klipschhorns with a Belle Klipsch center channel driven by McIntosh tube amps, McIntosh preamp and a nice turntable of the day. I was reminded of the impact Acoustic Research's first loudspeaker, with its relatively small sealed enclosure and "acoustic suspension" woofer, made in the mid-1950s. • Passive speakers, no matter how good they are, have serious flaws that can never be fixed without DSP. Why am I telling you this? With bass reproduction I find it's even more important with headroom. They are Gigantic, heavy, more powerful than a Diesel Locomotive ( even with a 40 watt. The claims for K-horns, if you were there at the start, did include all sorts of things that dropped by the wayside. Augmenting the La Scala's I'd also look into a design be Josh Ricci called the Skram. They describe what the product is actually doing regardless of whether or not the reviewer likes or dislikes the sound. Natural-sounding dynamics. If body, soul, and musicality were essentially to be found in a lab, things would be different. Personally I wouldn't go with a tune below 20Hz (which is rare anyway, and leads to monstrous-size cabs). But the complexity of the system took something away that I missed and I went back to passive crossovers and a really nice tube amplifier and a simpler system and I enjoyed that a lot more. Klipsch already builds far superior speakers to this one, and I'm not all that convinced that a DSP crossover will propel this speaker into SOTA territory. You are perhaps unaware that every Stereophile loudspeaker review includes a full analysis of the speaker's horizontal and vertical dispersion, in a form that I feel is more informative than a polar plot. Trust me on this. Thanks to the pioneering work of people like Jon Dahlquist, Jim Thiel, Richard Vandersteen, and John Fuselier (footnote 2), physical time alignment of drivers in a dynamic loudspeaker system is virtually a given these days, and the problem of baffle edge diffraction has been identified and smacked upside the head. The speaker field hasn't been entirely well-served by the so-called science of how uniformly the average, frequency-centric speaker energizes a room specifically suited to it.
