Hi,
Has anyone tried this driver or listened to it?
JBL-D2
There is a lengthy discussion on the Lansing Heritage forum about the M2 monitor that uses the D2: JBL Master Reference Monitor
I would sure like to know if it is available for purchase.

While I can't comment directly on the D2 I do see the 2408H mentioned in the article, I have those and they are pretty amazing. Here is a LOUD three tone distortion sweep at 100w, the cabinet is tuned to ~93Hz. Not bad for a "small" driver IMO. WAY WAY more output capability than needed for domestic HiFi. 
How low in frequency should a horn directivity pattern go for home audio?
The latest home audio high efficiency options:
coaxial ring radiator compression driver vs.
single Beryllium diaphragm compression driver vs.
Synergy Horn
JBL: two identical annular diaphragms combining in one common exit chamber.
BMS: one large annular midrange diaphragm combining with one ultra light high frequency diaphragm into a common exit chamber

The avsforum has a few threads on using BMS coaxial compression drivers with the "you can buy it now" SEOS 24 waveguide.
just another seos 24 build

You've been able to buy good medium format stuff for quite some time now... For less...
3722/4722 PTWG
I think there should be some distinction between what the M2 is as a system and what a DIY'r can do with the waveguide and compression driver. There is a gap there, and that gap is filled with $$$$ IMO.

Thanks for the replies guys.
I really would like to see the raw measurements of this driver, both diaphragms, to see how easy/hard this driver is to work with.
BTW, this will be for home use and I would try it on a few different horns as well.
My motivation is that I would very much like to see a driver that combines a large format diaphragm with a tweeter AND sound great at the same time. If we could knock path differences and lobing issues in the head, wouldn't that be fabulous!
PS. Who is selling these? (please provide a link)

Do you know
the combined diaphragm radiating area of the D2? in other words if this were a regular compression driver what size diaphragm would it be? three or four inch? Just curious. Thanks Best regards Moray James.
