To my untrained eye, the big diamond "mid range" looks interesting in a sort of platypus way. It would seem like it would be too big to have decent off-axis response up high (it is also listed as a tweeter), and the performance into the mid-bass area isn't great. Seems like this is either for an ultra high-end loudspeaker that still has a bottom that works to >1k, or its for a an ultra high-end two-way that someone wants to listen to by himself.

The big 11" "sandwich" driver seems a bit on the bizarre end. Stay well away from those speed-bump impedance bobbles. Yuck!

Finally they've got a decent web site up as opposed to the last attempt that had hardly been updated since 2005!!

Still, some of the data is confusing- like listing "diameter" for tweeters, and they have to be referring to the casing size, not the radiating diaphragm size.

Wish I could afford a pair of the BD30-6-036, I expect the 11" sandwich drier is only meant to be used up to 400 Hz or so.

This is such a huge improvement over the last version of their web site.

C78 is an interesting addition- wonder if that's been an OEM part only?

Check out the distortion graph on the C173-6-096E. The C90-6-079 is very good also.

Is the C78 not a renamed part?

The TSPs look a bit different than the C173n-T6-96 at Madisound, so perhaps the next generation? Or better testing? The FR plot looks very similar. I wonder if this is the same driver that is in the Kharma speakers that the high-end press drools over. Might be an interesting cost-no-object combination with the beryllium SS tweeter.

Very nice website! Finally they put this together. Some interesting drivers they have there, but I certainly won't be buying any of the diamond mids any time soon given the diamond 5 carat price tag that comes with it!

[JonMarsh]

Yeah, you probably have to have one of those Black AMEX cards to qualify for purchase...

I don't know why, but I just thought of checking their site since I hadn't in a long while. The 11" inch is of great interest to me...but I can't spend the 1-2k each that they most likely cost.

Marten Design recently release a speaker with those sandwich woofers for 130k Euro...

Which model, they already have very expensive diamond based towers.

I think that would be the Coltrane Momento, but those look like they are using the "standard" big ceramic woofer (listed in the product literature as a 9"). I don't see anything with the 11" in the product list or in the "news" (blog).

The problem, as I see it, with the 11" is the impedance bobbles that start at 1kHz that show-up, as expected, as spikes in the HD graphs, meaning something around a 200Hz Fc, depending upon slope:



For what these would undoubtedly cost, I expect there are comparable or better drivers that could still blend successfully with the full ceramics on top.

[chrismercurio]

those are the new 9" sandwich cones in the newest coltrane.

Yeah, interesting and strange at the same time! The scale they use for distortion measurements tends to obscure differences below a certain level- would much rather see a log scale or dB. Such is life...

Might be a touch too revealing to the wrong parties?

Is Marten Design's 9"woofer as C220? Though C220 series are called 8".
