There are a few things to consider when looking for a surround speaker. Danny much prefers the Omni-directional approach of the AV1-RS because it gives you a diffuse sound field with good frequency response throughout the room.
I have personally had mini monitors for surrounds and disliked it because they were just too directional. You knew the speaker was there this is not what surround sound is about. The other approaches di-poll etc just project sound everywhere and you get very inconstant frequency response in the room. My current surround speakers are omni-directional but not nearly as good as the AV1-RS however I much prefer them to other speakers I have used.
Ok now that we have established the merit of Omni-directional AV1-RS for surround sound let’s consider some aspects of this particular speaker. The choice to use a soft dome vs. the Neo is probably driven by the fact that the soft dome will have better vertical off axis frequency response. Given that it is above your head this is important and likely the reason Danny has never created a Neo Surround speaker. (I’m guessing here and could be totally wrong). Now let’s look at the driver configuration. I know you guys love multiple drivers, but a surround speaker mounted on the wall/ceiling has no baffle step correction and thus a single mid-woofer is all that is needed to keep up with the efficiency of either the soft dome or Neo tweeter. So less being more the AV1-RS is looking like the best candidate thus far for a number of reasons. The final reason is this. Look at this graph of where music is played.
Now look at where the AV-1RS is crossed roughly 1.8k. A lot of what you are listening to is coming from the mid-woof which is in the same family as the line arrays. Meaning it will fit very well. The tweeter is mostly adding ambiance.
I don’t think the AV-1RS always gets the respect it deserves. The Rodney Dangerfield of Danny’s speakers. Lol Over the years I have come to conclude it must be perfect for its intended job because Danny seems loath to mess with it.

Again I could be totally wrong about all this…
