Ojas (Devon Turnbull) and Klipsch (Roy Delgado) Collaboration - Just Announced

"Sandcast multicellular horn", eh? I wonder whether it rings (resonates) like some of the older cast horns.

Jim
I would guess not nearly as much. And I am not talking about hitting the horn when it is not installed, which makes the classics ring like a bell.

Classic: Fixed at one end, weighted at the other, that's a spring. A pre-loaded spring. Ready to oscillate once the energy overcomes the preload. And with a long mid horn....

This one seems to be affixed by the bottom of the horn and supported near the magnet, so I don't think you would get nearly the vertical motion you do with the classics.

I think I might fire up the modified heresies today, I am suddenly in the mood for some percussion played by compression drivers for some reason. :)
 
At one point, I really liked the aesthetics. He's a fashion designer, so he has some talents in blending everything together, furniture and audio, to create a cohesive look/siganture, with the hammertone or the pewter grey for instance.

Now it has become more of a gimmick where the guy is trying to milk the cow as much as possible, and he has also been using his Abloh / LV connections from his former life as a streetwear fashion designer to "luxurize" his products.
 
Lived with Altec 19 for a couple of years, and those I got for free. 9K is ridiculous and it is not a true multi cell to boot. I always felt that the 19 was good for music that got made with these as the mains, or equivalent, in the studio. Everything else not so much. But it's a lifestyle thing I guess.

It's a type of speaker that is more and more in fashion with the more "hipster youth with money" who don't want the mainstream stuff. They like the styling, and if the sound is not too bad, they think it's hifi. We got a bunch of hipster "listening bars" popping up in Europe, modelledd to the Japanese original, and they all use older Kiplish or Altec speaker setups mostly. Big woofers and big horns for the tweeter are what they want, and off course vinyl and tube amps. Music is mostly (modern) jazz, funk, soul, afrobeat or the "better electronic music"

I got also a lot of demands to design custom speakers like that (i did build a few) and i like that sound also. But i don't do old drivers mostly, i use modern high engineered pro drivers (B&C, BMS, Faital, Beyma, 18Sound, ...) and a well studied cabinet, and do only the design in most cases, the build is done by pro carpenters and the electronics also by people who knows. And those builds are also very expensive (5-25K depending on what and how) for a set.

But i don't claim superior sound, i tell them the sound will be coloured and how it will be and that the usual suspects of ASR are much cleaner in sound. I also always suggest dsp for crossover, but 90% insist that i design a passive crossover for it (that is also expensive to do right) so they can driver them with their vintage amps or tube amps. These people don't trust the "high end" industry and rather pay someone like me (i'm certainly not the only one who does it) to do a custom build. I'll be cheaper, better sounding and more exclusive than a Wilson or so... even if i'm not the best designer in the world (far from, but i know something). And it's not cheap to hire me or guy's doing similar thnigs down here. They know the snake oil stuff, but are still not in the ASR camp neighter as they still judge with their ears only. I always do and show measurements, but they don't care much about them.

Some brands also do small runs of a standard model, or build it to order. I don't have a production facility and it's a hobby, my (main) job is IT, not sound so my time is very limited. Ojas does something similar at the end, but way more organised and hyped, and he just copy old designs, I and the other guys I refer to make new, and don't hype ourselves. We got refered to. I did not intent to do this, speaker building was and still is my hobby, and some heared my stuff. So my designs that are build are very small in numbers (last year 5, of which only 4 were paying, one was an own project (for a close friend). This is because i want to keep it a hobby and still have time for my own projects.

But these type of speakers are certainly a hype among a small part of the youth, and it's a financial strong one. And Ojas knows that.

Normally the comments on most Guthenberg video's are overall positive the Ojas Speaker comments are ruthless qurious who is following Guthenberg mostly Vinyl tube enthousiast (guess target group Ojas) so i expected positive comments.

Wouldn't trust anything with Devons name on it. His bookshelf speaker kit he sells on his site shows he has no idea what he's doing. It's a jbl 328c driver with stock crossover tossed in a box. Problem is that driver is meant for in ceiling use and the crossover is tuned for that. Toss it on a smaller baffle, gonna need to change the xover. You can also buy a horn mod that unscrews the CD from the woofer and pops in a horn, but again with no crossover changes at all... Wait, did we just put a hole in the box by now having empty space where the CD used to be? Yup. Who know what the box tuning is now. Did I mention all this costs like ~$5,000?

Here's a sim of the 328c driver on Devon's kit baffle (green) compared to JBL provided response (red). Dude put absolutely zero effort into this "design" and charges a ton for it. One can only help he didn't have much hand in the filtering of the collaborative klipsch speaker

Wait, did we just put a hole in the box
If he is an honest person - there should be plugs in the upgrade kit. Or advice to plug the hole with something.
This is a real fast bass and clear sound. Despise the boomy hum and hollow voices :cool:
Those who wish can build a clone of this speaker.

What follows is less interesting.

No plugs, he has a video on how to install his horn mod.

I shared the same info here on some reddit threads but it ultimately made me just leave diyaudio sub because people there are just too damn stupid.

That looks like a reasonable (modest, actually) facsimile of the Altec Voice of the Theatre response. The VOT -- and, mind you, I love the danged things, even with their stock XOs -- was purpose built to speak through a movie theatre screen. A certain midrange forwardness is required to do that with elan.
The term Technicolor midrange sometimes applied to the VOTTs seems not misleading from my perspective. ;)

With some clearly-noted caveats (!), this is a "modern" FR curve measurement for a VOT-type loudspeaker: an A7 variant with 511B treble horn and relatively modern Altec drivers.
The bump is in a lower frequency band than I would have expected.

Col. Klipsch (himself, reputedly) compared the LaScala to a VOT product... some time ago. ;)

My own personal favorite VOTTs, FWIW are this pair of A5 loaded with 515B drivers, topped with 1505 horns loaded with AlNiCo 288 drivers, and tied together with Jean Hiraga's XOs. :) These are Gary Kaufman's, who uses a stereo 211 amp he designed and built to power them.

Note also the subwoofers, which are crafted (also by Gary) from a 210 cabinet split in half, each containing a 515B. :) Last I knew, he was using a pair of Mac MC-60s as his subwoofer amps. :cool:

Now those are multi cell horns. Nice. I do miss the VOT stuff. Very "open hearted" sound :)

The smoothness of 1505/288 combination astonishes me. Also the fact that one can stand 3 inches from them and they still sound smooth.

Well, we didn't know just how good the Neumann microphones really were, until the electronics around them improved. I am still a big fan of the Altec 604e for example. If I'd had the room, some Urei 813 A would not be out of the question :cool:

Pair of 604E in the basement. Pair of 604B, too.
I am a fan. :)
 
That frequency response is really bad. Why would you want a boost in the 300Hz-1KHz range? Theses speakers will sound muddy and without bass.
