Done and playing daily in my office.
The 9 drivers give much improved dynamics (in our room compared to the 4driver array) and excellent coherence as they are driven 100hz to their hf limit.
They needed compensation to tame a midrange bulge so some of the efficiency gain of a line array is lost but our 300B drive them comfortably in our largish room.
I would describe the sound as very silky smooth and and high resolution.
Combing and lobing are noticeable as you move around; the stereo image shifts as you move laterally and hfs drop out when moing vertically so listening requires staying within a narrow sweet spot.
Because of that and the cost (9 x 250USD for the drivers alone), I don't think this could be a commercial product as it stands. I'm thinking of adding a single ribbon tweeter (a Jordan would be better but a Fountek ribbon would pretty well match the system in efficiency) crossed over at about 6K (where combing becomes noticeable) to see if the hf issues can be resolved. Power tapering is another option as it would be nice to stick to all Jordan drivers.Will post more as we have it.
