SL is so excited...

Someone that builds loudspeakers that look like the below noted example I do not take very seriously I'm afraid.



Cheers,

Siegfried Linkwitz? Maybe you should.....

Sometimes I wonder about some of the folks around here, about what they take seriously and what they don't....

Oh, don't get me wrong, he knows his theory, and probably has a firmer grasp of how filtering works than the majority of us, esp. when done actively. But his loudspeakers are just not at the same level. Whether it is his woodworking skills or simply the fact that he has a lesser understanding or grasp of how things on paper or in theory translate to something in the real world?

Cheers,

Sander.

Ssasen, I don't know why have you reached to that conclusion, but as far as I understand things, SL seems one of the few that knows what he's talking about. I've read all his web, studied it, and built a 3way based on his findings (not exactly an orion, though). His comprehension of theory is very good, and the sound of my dipoles is extraordinary.
I assume then that you have listened to an Orion. What's your opinion on it's sound?

Raka,

Yes, I've heard the Orions before, I wasn't that impressed to be honest. It could do with quite a number of structural improvements, which Siegfried Linkwitz apparantly seems not to care about. For example glaring oversights which can be spotted right away are the mounting of the mid, the fact that there's obvious baffle reflections and defractions due to the way things are constructed and the simple fact that a H-frame is prone to resonate, which isn't a concern with 24dB/oct active filtering I'm sure, but will not work well with lower order filtering.

Cheers,

Sander.

Well, those points have been dismissed, or tested and dismissed, but what you will have to admit is that your points here (and many others) have been noted by him, and after some thought or test (or feeling) have been included or abandoned. As I see him, his theories and products are very coherent.
Anyway, this thread is not to qualify or disqualify him as a good designer, but to point out that SL has made a discovery in his way, which is nothing more and nothing less that the room is not always an enemy. Which in my opinion, is a milestone in his recent thinking in some way.

Most speaker designers will tell you that the really good speakers do not sound impressive at first listening.

To those of us who have as much experience using H-P gear that SL was involved with designing, he gets away with minor faux pas, as you descibe.

So there......!

Stop jumping to conclusions based on your personal bias and lack of even the most basic research. If you have real suggestions there is a whole forum of users to try them out on. I am getting tired of some of the incredible intelectual laziness around here. Got some ideas, I'll bet a bunch of people would love try them out.

I'm not jumping to conclusions, nor do I have a personal bias. I've been building loudspeakers since I was 16, that's about 17-years of experience by now. I've built just about anything, from full range electrostatic loudspeakers to minute monitors for desktop use and everything in between. And no, I don't just mount a driver in a wooden box, I go the extra mile, simulations, measurements, etc.

When I look at the detailed pictures on his website for the Orion the comments I made in my previous post are some of the things that immediately come to mind. Whether those have been dealt with I don't know, if so, he needs to update those pictures.

As for your suggestion to read up on the current status of this design, I don't have time to debug someone else's design by going over umpteen forum posts. If changes have been made I would expect the website, including the pictures, to be the status quo.

If he can't be arsed to do that the information, or at least the pictures, is useless at best. Much like an old user manual that's has been rewritten a number of times becomes somewhat obsolete.

Cheers,

Sander.

By the way, in case someone thinks I have some personal prejudice against Mr. Linkwitz, I don't. I think he's made some incredible progress in many areas and has inspired many to explore other avenues. His exact and very coherent way of detailing his work has been both fun to read as well as a good example on how to present difficult information to a broad audience.

In this case I just have a fair amount of experience of my own and am confident that his Orion design can certainly be improved upon in certain areas. I might come off sounding like a snob that knows better, but in that case I fit in well with the likes of Fred et al I presume

Cheers,

Sander.

You don't even have time to read the links that refuted your statement:



PS

I built my first loudspeakers when I was 18. KEF drivers in tapered transmission lines with wool damping material. I also have modified every speaker I have ever owned (and quite a few others)..... I still think SL knows what he is doing. Almost anything can be improved though. Shoot him an Email or join his forum.




Or even one that doesn't.......

I really don't get this attitude about SL when his whole website flies in the face of it. He seems to include an incredible amount of input from others.

I thought Sander was a "digit-widget/"bit-head". Didn't know he was one of us.

(This is the point where Phred drags up a still from the movie "Freaks".) (If you can't find it, I can send it to you. May take a while, so do it yourself.)

I was swayed to the dark side in college, by preferring to spend more time in the virtual domain whilst doing coding and what not rather than tinkering with loudspeakers, amplifiers and all else audio related, which includes listening to music. Past few years I've been slowly picking up on my old favaorite hobby and pasttime. As Luke Skywalker once said 'I sense there's still good left in him' so I guess I'm still not beyond saving.

Cheers,

Sander.

So you really have gone over the dark side. We may welcome you back. If you repudiate your code-writing ways.
