Gee, that sure looks like a Linaeum tweeter all growed up.

I think they are segmented.

What is the horizontal and vertical sound dispersion?

Horizontal dispersion in the A9 Array is 90° at 10KHz, 120° below 5KHz. Vertical dispersion is variable and it can be set from 0° to 80°. Splaying angle between rows can be changed in 2.5° increments, from 0° to 10° total in four fixed increments. For example, we were able to evenly cover 1/4th of the Arco Arena in Sacramento, California with only one MAD Array, i.e. we could cover the entire Arena with only 4 Arrays. Custom design of the Array can achieve any dispersion angle in both horizontal and vertical plane, from 0° to 360°.

Plane sources (except NXT panels) beam narrow on short distances, but are probably excellent for PA.

It would be interesting to guess how they behave at short distance. This is a doubt that I still have. I really like the flexibility of such small panels that I can arrange with creativity.

I've listened to an array of 9 neo-8 (old models). It was pretty good, esp. on dynamics. But on strings it didnt beat Precide Kithara AMT.

Next, I need to check a true ribbon such as Transmission Audio.
