Is that on the pictures NAT monoblocks?

No! It's Martens own Mono Power Amp. M-Amp. Designed to match their speakers perfect.

One reason for why it is so expensive is the quit expensive elements all over the speaker. 16 membranes they are. The lower diamond tweeter costs 23.000USD for one. :yes:

Where is it likely to debut CES ? or then MOC next year ....

Leif by Marten told me that it will be shown at CES.

A lot of cheap crossover parts correcting the timing errors for all the expensive drivers and very big cabinet.
Why not use Duelund in this very expensive speaker?

How do you know that the crossover parts are cheap???
Due to my knowledge about the crossover, there is no cheap parts present at all. They are very careful selected from the top products out there.

The whole idea of the front membrane is that the they play without any timing errors. The membranes are all in the same line. That is not so common. The crossover can therefore be very simple. The bas membranes in the back is just playing below 40hz and since the wavelength is long (longer than most of the listening rooms out there) the positioning of these are less important as it is higher up in frequences.

Some of the words that comes to me about the speaker is the best timing I'v heard, definition and dynamik presentation.

I know Leif quite well from having owned Marten Coltranes before and spoken to him on many occasions. These new speakers look interesting. I saw the new Accuton sandwich bass drivers recently when I inspected the new Coltrane Tenor's in my Dealer's showroom. It looks like they're being used in the upper bass-mid-bass region in this application.

In regards to the two diamond tweeters you mentioned. Actually the larger diamond driver is a Diamond midrange. You mentioned he will be running 2 x diamond midrange & 2 x diamond tweeters. That would mean he is adding a rear-firing diamond midrange & tweeter, but the open cavity in the mock up suggests he might be using a transmission line mid/tweeter arrangement?

Following on from the above, Leif is now using the latest Cell-concept diamond midrange and tweeter which have lower distortion than the previous generation, better decay & are inherently time coherent in a flat front baffle as they share the same acoustic center. But i'm surprised Marten are not using the latest black-coated ceramic (BCC) drivers as per Avalon's new Tesseract, which by the way also uses the Cell-concept diamond midrange and tweeter & comes in $200k cheaper? I can only assume they couldn't reach an agreement to use these drivers :scratch2:

Hi Bodhisattva!

I never mentioned 2 diamond midrange. There is 2 midrange membrane one white smaller and just below it's one convex midrange element that looks like most of the rest.

I wrote in earlier post: "The speaker is 5 way. 6 bas elements, 17-40 hz plays backwords. 6 elements in the upper and lower front plays the rest of the bas, 2 plays midrange and two diamondtweeters the treble."

The bigger of the 2 diamonds play 4000-8000hz, I'm pretty sure. Perhaps it's in between midrange and tweeter.
4000-8000hz tweets i my ear.:D

OK, but that is how your description read. This should be a superb speaker, but for my money I would bank $200k and buy the Avalon Teseract..:yes:
