Tell us a little bit about these babies! I am curious about which drivers you are using? Mids? Tweets?
How do they sound? Can you offer any of your subjective opinions on these arrays versus any other
speakers that you may have heard?

Are these Legendre shaded? How do you deal with the HF loss in arrays that need to deliver high SPL in a home theater environment? What is their sensitivity? Are the surround arrays curved or smaller?
These look like a great option for those without much room behind a screen. Arrays offer some terrific advantages: 3dB loss/doubling distance for better seat to seat variation in SPL, vertical directivity control (esp. when properly shaded, lobing can be nearly eliminated), high WAF, but also have distinct challenges: HF loss and subsequent sensitivity loss depending on how you mitigate, and the narrowing directivity with increasing frequency such that they have small listening windows unless delayed/shaded like a CBT. In a home theater environment with listener positions known, they can work very well. But in a multipurpose room, you need either taller arrays or CBT.
These look terrific!

The shading is proprietary to this design but I can tell you that it works very well. I've set up a test rig that allows me to experiment with Hann,Legendre,etc. so I can compare the results very quickly. Sensitivity is in the 93db range after shading is applied. In some frequencies you actually incease output with the shading due to reducing phase cancellation.
This system is using a DEQX for DSP crossover / EQ functions so we can easily adjust the balance for HF loss. Due to the room design (all speakers hidden) it dictated straight cabinets so the surrounds are straight as well.

Very nice! Great sensitivity as well! Will these get documented on the Selah Audio site like the other arrays, with measurements, etc?
Playing around with shading can yield some not-so-intuitive effects on freq response and directivity. Glad you found a good solution. Shading the MF and HF lines differently can really help things, as I'm sure you already know.
If you can, post up pics of the implemented system before they are hidden from view with screen/cloth.
