I did. He says he’s not finished what he’s trying to accomplish.  So it’ll be interesting to hear his speakers once he’s done. 

When he's finished? He's going to need dead man's curve, by the age of him.lol

From a post today from Vandersteens Facebook page:

 

Every once in a while and old friend appears in a forum. Tom Thiel explains why time and phase correct speakers matter, and helps understand the connection with these speakers.

Andy2 and all -

 

I say that neither Jim nor Thiel Audio would espouse valuing ’"time coherence above other aspects of sound reproduction". Our company was built around addressing and honoring ALL aspects of sonic/signal/musical reproduction as a whole. Most designers - products minimize the importance of the time-phase aspects of fidelity, especially in the day that we did it. Only a handful of brands made time/phase behavior important - including Thiel, Vandersteen and Dunlavy and Quad, and possibly some smaller attempts.

Note our attention to time-phase was not above other aspects, but as one among several necessary ingredients for faithful representation of the musical signal.

Having paid attention to this stuff for half a century, my perspective is that keeping time-phase correct allows the ear-brain to pay attention to the playback signal as though it were real - thereby permitting a more holistic, immersive experience of the music. Although we rarely admit it, we humans do not possess unlimited brain-power. Work is required to reconstruct a musical signal that is missing its time domain content into an interpretation that makes sense. That effort subtracts from the state of consciousness that is possible when experiencing real music, either in its un-recorded state or its time-phase correct played back state.

Among the most frequent comments re Thiel/Van/Dun/Quad, etc. are ’naturalness’ and ’image density’. These are psychoacoustic attributes facilitated by the addition of phase-time correctness to the other realms of dynamic and tonal correctness.

I assess that designing for all of the musical aspects rather than discounting or fudging against the time-phase aspect requires an order of magnitude more effort. Everything becomes extremely more complex and difficult.

I can only afford a summary overview, the details took a career to address, and the work is still not finished."

Thanks for posting this.

Your post sent me off on a hunt for more information about the subject of time phase correction in audio.

A very interesting subject.

thanks.  
 

It’s interesting indeed.  It matters more to some people and less to others.  once I heard a time and phase correct speaker I  went down that path.  From Theils to Vandersteen.

Surely, it's all very well to have drivers located so that their result is time-coherent ... but, to get a complete result, you need to implement FIR filters in the XO - not just IIR filters?

 

Hence ... you need to use DSP-generated filters - not analogue filters.

 

Sorry no idea about this.  
 

richard Vandersteen posted this re DSP on his forum we DSP: 

 

It does but with enough latency DSP can totally reconstruct any signal to be Time and Phase correct but all this processing is not free and has a significant sonic penalty as all digital processing does.   RV

 

 

if you wish to query more suggest you post on the Vandersteen forum located at the vandy website or email Vandersteen directly.  Richard will reply to you.  
 

Cheers 
 

 

 

Nice video here re time and phase:

I think that the explanation by the engineer from Gauder Akustik, in this video just released by Jay, is worth viewing in regard to the discussion above.

I now have no more room on my walls AND my floor!! But I loved these so much I had to have them!

 

First:

 

TICKETS PLEASE BY BLAISE HAYWARD - Led Zeppelin, Seattle 1977

Led Zeppelin, The Kingdome, Seattle, WA 1977

This was Led Zeppelin’s first show after a 3 week break to wrap up their epic 1977 tour. Over 62,000 fans packed the Kingdome for a 19 song, 3 1/2 hour set. Jimmy Page wore his famous White Dragon Suit for the last time on stage, and Robert Plant had promised “blood, thunder and the hammer of the gods”. By all accounts Zeppelin delivered, with Plant commenting at one point during the set that he was deaf in one ear. The iconic Kingdome held its final concert played by U2 in 1997 before being demolished in 2000.

What pressing/format do you prefer? 
 

 

I have preferred the MOFI version, I recently bought the anniversary edition box set, and I haven't had a chance to listen to it. What is your preferred version?

Mofi is nice.  
 

for digital there is a west German first pressing cd (hard to find unfortunately) 

 

for analog the release in the LP box set…

Where do you find all this stuff?

You collect some fantastic memorabilia.

I think I have three copies; you can never have too many! (CD West German Vertigo Pressing)

I showed my BIL last week, and he gave me the strangest look, dunno why?!

The CD to hunt for in the German Vertigo. It has MADE IN W. GERMANY on the label side. No Germany on the either side near the small center hole.

 

Great album! 🙂

LOL re the ceiling. I think I saw on a TV show a guy who had so much stuff to hang he was also using the ceiling!! 

 

I don't think I would do that!! (famous last words?!)  🙂
