The above mentioned configuration could also be used for the Klipsch La Scala AL5 ....... La Scala AL5 was reviewed with measurements by Hi-Fi News :-) ........ A pair of La Scala speakers mated to a pair of SVS woofers is a thing to behold! I think your enjoyment of the horns will be magnified when accompanied by these priceless writings and you may make changes that will improve the sound. Klipsch built its name in audio thanks to great speakers like the La Scala and the Cornwall. 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. May be J-10 could review the new Synergistic Research $10,000 'World's reference power cable' for Stereophile? This is no small thing. If you want speakers that measure the way JA and others say a speaker should measure, then go buy some. By measuring it in a driveway you've robbed it of a huge portion of it's bass In a perfect world if you found a large building exterior in the shape of an L and stuck the speaker in the corner you could maintain the flare, and then measured ground plane you would have gotten much closer to the actual capabilities of the speaker. But according to head designer Roy Delgado, who began his career working closely alongside Paul Klipschand has now been with the company for 33 years"the Klipschorn's low-frequency horn is the one thing that has changed the least. My only quibble would be the normalization he uses for lateral off axis. I Don't know exactly what aspect of sub 50Hz you're addressing here (other than "realism," but more on that later), whether it's the overall nature of bass reproduction and/or whether it concerns the Klipschorn's hardly extending down that low (it seems their "hard deck" sits at some 35-40Hz). Horns, tapped horns, FLH's and 6th order bandpass iterations typically with pro drivers from 15-21" - all of this may seem like madness in a domestic environment (and believe me, potentially it is), but truly this is about the best quality bass reproduction that can be had, and subs that integrates the best way with the mains - including not least high sensitivity designs like the La Scala. Also, the bass cabinet vibrations are a bit concerning as well. AD could do some follow-up reviews :-) ........ Too late: Because we needed to take photos for the cover--and also because Art needed to return to his reference system in order to review other stuff, the Khorns were removed promptly and shipped out. I could easily make a Rival speaker have flatter frequency response. Hmmm, popcorn ready, I'll be waiting for this answer myself! !....this is crazy. In that case, "Nervous Breakdown" can happen :-) ......... We were waiting for you to be the 100th commentator on this Klipschorn forum, Ortofan :-) ...... Read, Ken Pohlmann's article 'Are you a watch guy?' Klipsch Audio quality is Stunning, staggering even beautiful. Toole/Keele/Geddes say that polar plots (or early-reflection directivity index) are important. I'd love to see what measurements JA would get with an active, DSP'd Khorn. 4500Hz, If you really want to hear what the very best Khorns sound like, you'll need to hear some that have the full compliment of Volti Audio Klipsch Upgrades in them. We were chatting just after hearing a demo of an excellent, modestly priced loudspeaker. Buy Klipsch to match Room size then brace yourself for Hockey Arena SPL capability. “ Nowadays speakers with horn-loaded woofers are extremely rare, but—trust me on this—nothing pressurizes a room like a pair of K-Horns with 15-inch bass drivers. weren't for it.I bought my Pair in 1983 for 2383.00 tax included.Thanks Art(I know u weren't with the magazine back then)for FINALLY doing the review,BTW wish u had tried with solid state amp or av receiver.that's where the BASS is. After he left they cranked it up even louder as if to say to Paul "these are what horns are supposed to sound like!". First let me be clear..it's tough measuring a corner horn like this. Myself I'm using a pair of lilmike's MicroWrecker tapped horns, and had a cabinet maker build the enclosures. 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. I found that I liked them best when tight in the corners, and less for every little bit I moved them out of the corners. The proviso being that the room has to sound good before you put the speakers in it. Every Stereophile loudspeaker review includes the measured step response. I was never all that happy with the amp, the dude with the wire [sorry, can't recall his name, he lived in Berkeley and wasn't Ric Schultz, another 'wirehead'] happened to have a pair of Kilpschorns in an [tiny] acoustically inappropriate room. It raises several interesting questions, but I'll exercise restraint and keep this reasonably short. It's surprising as it isn't to see JA effectively siding with Mr. Villchur's statements, when the latter is the man promoting his own invention to cater to buyers who're mostly concerned with size and looks. I managed to find a pair of bookshelf Klipsch speakers from the 1990s at a yard sale, $15 for the pair. - Buy a copy of the previously mentioned compilation of Paul's "Dope from Hope". Klipsch Klipsch Heritage Series Groove at Amazon "This compact speaker boasts a massive sound capable of playback from any Bluetooth enabled device or via 3.5mm AUX cable." Bass Bins. In its latest rendition, this historic speaker boasts an all-new neodymium tweeter, premium wire management system, and fully-enclosed design for flexible placement. And, I would like to add that the Khorns aren't wholly representative of the bigger, more sensitive segment of speakers. I think earlier remarks concerning room reinforcement to be pretty on point, and I'd add that the lowest octaves for this speaker really need a big room. There's money to be saved with DIY, and finding the right design from named individuals is a great way to go with this segment of subs. Combing the experience of audio pros reveals and confirms that historical audiophile preference has indeed identified good-sounding speakers and for very specific reasons, and not the current trend of what they do in directions other than at the listener. Be respectful, keep it civil and stay on topic. KLIPSCH HERITAGE AK6 KHORNS/AL5 LA SCALAS for sale. Not being snarky here - I'm confident none of my customers would change a thing.

If my observation is correct, then the frontier moves either to fine-tuning--raising the bar on classical performance--or in designing interesting alternatives to the "classic" design. You know, basically my garage system ;). After all any audio equipment is made with test measurements and ee calculations, if not, I wouldn't even spit on it, it'll be rubbish. I suspect you'd have a different result if you measured it in room. ... fully horn-loaded loudspeaker that laid the foundation for the Klipsch brand. The sheer tactile immediacy and startling clarity of the solo tenor saxes on Sonny Rollins and Coleman Hawkins' Sonny Meets Hawk! What a gutsy conclusion. Needless to say, I too would love to see how the modern K-horns would measure properly DSP'd - but I would also like to request that John try to measure a vintage Klipschorn in good condition to see how that compares to the modern version. I'm not so sure this is a bad thing, really. Just huge fun. And of course, tons of other speakers that time align as well. ;-). I began with the backs of the Klipschorn AK6s a short distance from the front walltheir 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 otherand with the speakers slightly toed-in toward the center listening seat. I've restored several pairs of Khorns where I added backs and bracing to enclose the bass horns (I have webpages showing the restoration process). - Get a single middle speaker to complete the sound stage. 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. I admit to enjoying that speaker more than the Klipschorn. https://www.youtube.com/watch?v=MeWC59FJqGc. So the speakers were in the corners of the W but still pointed straight forward.

I'm hunting for a used pair of smaller Klipsch : Hersey, Cornwall, Forte ( the smaller, the better ). That is to say: a bigger air radiation area and much higher efficiency equates into less cone movement and lower distortion. Wonder what JA1's measurements would show? I own KEF LS50's for my mains in my system. Apropos before mentioned madness or "wretched excess": overkill to some is just an approximation to sufficient headroom to others. In this age of cheap silicon and relatively mature off-the-shelfs, c'mon Klipsch, get with the damn program for a $15k speaker! Klipsch Klipschorn AK6 Loudspeaker (each) Must be purchased in pairs. Paul Klipsch recommended the 1.0 to 0.618 ratio of distance between speakers to distance from front wall to back wall and its important. Technical Editor, Stereophile. Ignorance about real aspects of real things like the very large WMTMW you mention is proof of such assumptions. 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 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. Moving fast forward: time alignment is solved by mounting the tweeter on top, aligned with the midrange horn. 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. Very impressive demo. I don't say this lightly...I am an AES member.... Those measurements are not what you expect from a $15k speaker, www.hifinews.com/content/klipsch-la-scala-al5-loudspeaker-lab-report. In order to reproduce those peaks without clipping, one's amplifier would need to be capable of a peak power output about 160 times higher than that required for the average listening level. This is just speculation, but I'm with those who say that this speaker probably still needs very tight corner placement (despite the new back panels and in contrast to the company's recommendations) and is best used in large rooms where you're mainly listening to the reverberant field. • Passive speakers, no matter how good they are, have serious flaws that can never be fixed without DSP. I would add to that though: shame on Klipsch for not seeing that themselves. Sorry Jim, I wasn't paying attention to the comment section and just now saw your post. 2. It took about an hour and a half to get the four separate cabinets unpacked and in the door, after which things went reasonably well. 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.

He credits Noel Lee for a business education and left Monster a few years later to set up his own PR company, Scull Communications, which is still ongoing. They measured dynamic compression/linearity, frequency response and distortion. Ken. P.S. It would be interesting to see if there was any correlation between what Art heard and what JA1 would measure. polyimide, Tractrix Horn, For its wisdom, candor, and sheer generosity, this post deserves to be at the top of the page. He was not a super friendly kind of guy. -Whether rooms are as critical as conventional wisdom assumes is another argument compounded by conflicts in Objectivist dogma. I visited the Hope Ark factory back in the early 70's as a teenager. Skip to main content.ca. The mechanism, though difficult to perfect, is easy to understand: A loudspeaker driver is a notoriously inefficient thing, owing to a severe impedance mismatch between its diaphragm and the volume of air in the listening room; a horn acts as a transformer between the two, making it far easier for the vibrating diaphragm to get a "bite" on the air. Klipsch has a rich heritage of emotion, power, and efficiency. Probably get a nice audio component or even TV space in the middle with some deep record shelves on the sides. They were all very good, but they didn't measure temporal performance. This is an absolute surety. 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. The company seems to think so: In September 2018, they introduced a new, easier-to-install version of the world's most long-lived commercial loudspeaker. For best results, Klipsch highly recommends the Klipschorn be placed in the proximity of a corner.". They are two entirely different things, and if one doesn't suit your tastes, you should buy something different. But that's not "wrong" either. However, it seems from the measurements, to me at least, that when used with a low-impedance SS amp, the Khorns would be pretty hot. I was hoping to meet him. But if you're going to do the review...and then publish these measurements....you've got to do better than what was published here. • Once you have addressed the temporal issues with DSP, the remaining speaker and room related issues are much easier to address with EQ in DSP.

Mark Henninger. Much of what has been learned in the years since the Khorns "inception" back in the 40's is integrated in newer horn designs that need not comply with a vintage approach, and that truly gives you more of the ability to have your cake as well as eating it too. I put felt sliders under the assembled speakers as an aid in positioning them and soon found that the closer they were to the corners of my room, the better these new Klipschorns sounded. In fact all Rival owners could do the same thing by simply increasing the output of the midrange horn to match the output of the woofer and tweeter.
