Lot's of topics for discussion here for us all:
Three most important things in Audio reproduction: Keep the noise levels low, the power high and the room diffuse.

Thanks! for sharing.
I read you are a manufacturer- what do you make/produce?
I work for Bruel & Kjaer - sound measurement folks.

you learn and see a lot by clicking their moniker to see their profile and gallery for some. The answer to your question is found there as well.
... no Linkwitz for me in the near future.That's not even taking into account 20+ piece-of-shit opamps in series, in a state-of-the-art ASP crossover, placed in front of piece-of-shit ATI multi-channel amplifiers (which of course do not affect sound quality in any way), connected to his state-of-the-art speakers, pushed hard together with those POS amplifiers.
"10 - Provide 8 channels of power amplification of 40 W/channel minimum. Low distortion, low output impedance, solid-state amplifiers are preferred.
* Alternatively, a well suited 12 x 60 W or a 6 x 180 W amplifier is available through Linkwitz Lab.*"

When did you hear them?
I've always wondered how they'd play...

You are participating in one at this very moment.
When it comes to audio, I am a paganist - which shouldn't be surprising, considering that I lean that way when it comes to music, too.
It's the monotheism in audio that I object to.
...- theism?
What about "true believers"?
Some would say the whole high-end audio industry (listeners too) is one. :)
There's so much self-deception and intellectual dishonesty going on that many times it's impossible to tell what's not. :)
At least nobody's forcing anybody to buy anything. People are perfectly free to keep their wallets in their pockets.

I have no experience with active speakers and so have no opinion on their possible merit over a passive design.
The Orion seems awfully complicated, but those who have it seem to believe it was worth it.
Is it the design, the sound or active speakers that you don't care for?
Behringer Truth wins...
And
More from DIY Audio
Especially the fact that it's coming from not exactly "audiophile" camp, either.
All speakers make compromises. Different configurations make different compromises. What ever you value you most and/or hate the most will enter into which type of speaker sounds the 'best' to you. That's true for Linkwitz also.
I've heard his latest design. And it's really excellent. And, for what it's worth, I use conventional box speakers that are also excellent.
And perhaps you can forgive Linkwitz a bit. For whatever you think he's done badly, he developed the Linkwitz/Riley crossover which is used by tons of designers because it's really good and responsible for a lot of the improvement in reproduction since it came out.
In my earlier years I mucked out horse stalls.
.
Wasn't Linkwitz involved with the not very stable Peter Aczel in some ill-fated mess a few years ago? A venture that severely tarnished both their reputations.
My apologies in advance if I'm mistaken.
Cheers,
Al
...interesting presentation if self-serving.Linkwitz has always been a pretty controversial figure in audio.
If he's right, why haven't his designs become more popular?
His own speakers are limited production, but that doesn't prevent others from adapting his ideas.
I can't think of many speakers today with open baffles, for example, except Marchisotto's Nolas, which evolved from Dahlquist DQ-10s.

which sounded quite good at the The Show Newport 2014

They are geared primarily to the DIY crowd and regardless of their performance, are awkward looking at best.

Sure there are, but you must think outside of the box (pun intended). Most all planars are effectively open baffle radiators. Even Siggy gave Magneplanars faint praise even if "its interaction with the room difficult to predict" . I've been a planar enthusiast since the very first time I heard them forty years ago.
As for me, I think the overall challenge is practical in nature. The placement of open baffles (of all types) is more critical and in many cases, requires more space behind them for optimal results. And I definitely disagree with him about room treatments:
"Absorbers, diffusers and electronic room equalization will change the sound, but these are only remedies to an improperly designed loudspeaker."
Sure Siggy, your OBs will sound gorgeous in an untreated garage, right? And what's up with all the underlining? Are those your speech cues as when to place emphasis? :)
As someone who does a bit of public speaking, the underlining is likely a way for not losing your place in the text. It does mean, however that the speaker may be reading the presentation word for word.But if you were in the audience you wouldn't know that. The audience would see the presentation slides, only the speaker would see the detailed notes. Both are shown so that the full text would be available.
The other option, and the one recommended is to write the speech first and to ensure that it can stand on its own merits. That speech is then the basis for the notes with the presentation.
Edit: It does seem like a long and boring presentation with a lot of unecessary detail and too much repetition. Inexperienced speakers will tend to do that, throwing in everything and the kitchen sink.
You have to know who your audience will be and tailor the presentation to that knowledge base. With a meeting of professionals and peers, a lot of that information would have already been known.
Too much detail distracts from the true message, it gets lost in the static. The whole point was that improvements have been made in the last 50 years and that there's room for more. I think it would have been more effective to discuss what those improvements could be and to leave out the history lesson.

As do I. Slide content too busy.

Yep.
Dahlquist DQ-10's, that is.
Wishing I could buy a new pair.

...was blown over by them when I came across them there in 1977 at Huntington Beach.
Started me in high end.
Yup, me too. Wandered into Continental Sound on St. Charles Rock road in St. Louis where I heard a big G.A.S. rack driving DQ-10's and stereo subs through a Dahlquist crossover.
Changed my life.
Until then I thought stereo was a big receiver and a pair of speakers on the floor.

Five grand for a new pair of DQ-10's.

that retailed new in 1974 for $395.00. That is about $2000.00 in current dollars.

Carl's current product is so pricey. I think the KO is the closest thing in the Nola line, but runs a cool ten grand. He designed the later DQ20 along with some other Dahlquist products.
I guess that's chump change, however, as compared with the $197k Concert Grand and the $278k Grand Reference VI!
