we are able to see through sales pitch and other BS to the point

Where do you read that? I watched the video and talked to him myself. I don't know of any sales pitch and there certainly wasn't any BS.

The part that I found arrogant is the notion of exclusivity.

The "notion of exclusivity" only stems from the fact that he makes a living as an engineer at an institute for the study of human hearing and wasn't really interested in building speakers in quantity.

Actually, somehow I believe that your presentation of this dude made him look worse then he really is.

I don't understand why you are being so unreasonable. Do you take girl pills? The main reason I started this thread is I found it interesting that someone could consider objective and subjective testing methods on near equal terms and produce an outstanding result. So far most of the subsequent comments have concerned the way they looked.

Aside from the thread title and the fact that he mentions those same words in his video interview I see nothing of substance to indulge in any conversation outside of how they look. There's no measurements, there's no conversation, reasoning or methodology to augment the subject title of this thread. All the video interview told us was that he built some speakers when he was nipper and accidentally fell into building loudspeakers through his research explorations.

I'm not sure what you expected given this lack of material. Its not really thought provoking stuff. Most use subjective and objective goals when designing ie. build it up with objectivity and tweak/voice with subjectivity but be wary of completely rely on one or the other.

There's nothing new or interesting in his methodology, at least not from the very tiny amount of information presented in this thread.
 
Well, I think the man is very brave to present his speakers with that design and finish, and I would say that he must be very confident in the sound
But I am obviously a strange guy who prefers simple design and rough finish design
But with an exclusive veneer he could probably multiply the price...look at WLM, my hart jumps looking at the prices...but fantastic veneering

does anyone know what drivers are used?


All elements he uses are custom, and can be bought by him personally if you want to. The 8" is probaby rather similar to the one he uses in his INO speaker pi60 which have been optimized for many many years. Nothing is left to chance. Regarding the step in the baffle; It is not a problem, since the reflection from the shelf is directed upwards, the diffraction from the inner edge is null and the diffraction from the outer edge is of course calculated into the design, both regarding the base and the tweeter. I hope someone understand what I´m rambling on about, I´m trying to translate from a swedish forum.🙂 Oh, yes, and the depth of the shelf allows for perfect aligning of the origin of the waveform propagating from the drivers to line up...:smash:
 
Sorry if you think I'm trying to sell his speakers, that was not my intention. Just to "defend" a nice person who I consider a great tutor (He is my biggest source of inspiration then comes Linkwitz.) who I feel is getting prematurely judged.😉 Sorry, but I don't like it when people speak of others who aren't there to speak for themselves... Here are some articles he has written (translated to English) and a long and very interesting interview with him, unfortunately in swedish.🙁

The site says, regarding the crossover: "2-7kHz. Non-schoolbook function."

What does that mean? He's saying what it isn't (sort of - "schoolbook" is rather general) but not what it IS, which would be a lot more informative.

Probably a translation issue that should read non-textbook. Most likely that means its some arbitrary transfer function, probably designed to yield accurate acoustic slopes. Since this is a passive network its not going to be anything fancy such as a Neville/Thiele or 96th order LR.
 
It kind of sounded like a marketing technique - "Ours is different, but we won't tell you how - it's proprietary but take our word for it that it's better than anyone else's and makes our speakers worth the money."

Being a little cynical there - I did watch most of the video but there was nothing technical in it whatsoever, and when he said people were waiting 2 years to buy his speakers I just had to laugh - didn't any of them go out and listen to anything else while they were waiting?

Also, regarding translation - "2-7kHz" - I wonder if it was supposed to read 2.7.

Just a guess but might mean the driver overlap region is 2-7Khz which would logically put the XO at 4.5Khz assuming symmetrical slopes, if asymmetrical then who knows exactly what.

And yes the cynic in me also agrees with you about the proprietary thing. Its easy enough to make anything sound exclusive but its still valid all the same. I mean look at Helmholtz resonator bit, he could have just said ported but used the correct terminology.
 
At the end of the day I'd want to see measurements - anybody can make a claim - I like data.

Why don,t ya mail the man and ask him to give you the measurements you want.. ?🙂

Maybe English is,nt his first language so some lines might come out weird? 🙂 However, there proberly where people waiting for him to go"public" with his designs..

That was really a more generic statement about assessing loudspeaker performance.

Nah - the interview seemed to say people were on a waiting list to buy the speakers. A small loudspeaker company going public is doubtful - there would never be enough revenue to generate significant dividends for public investment. And his command of the English language seems to be pretty decent.
