Why not just build a set of Orions?

Uhm, I don't mean to offend you, but the two pairs of Orions that I heard didn't sound very good. They were both terribly veiled and boring. I'm sure it was a question of amp choices......

I doubt it was a question of amp choice. But for a 'terribly veiled and boring' speaker the Orions certainly seem to have proved 'inspirational'.
Please do not try to read into my post anything more than I stated. I heard two different sets of Orions, both owner built. I had heard ...........
How cosmic is this? As I was typing my response, my Super V kits arrived!!! THANK YOU, DANNY! 
....that they were good sounding speakers. I was excited to hear them and was very disappointed on both occasions. I am not slamming the design in any way. I am simply stating that I don't think I have heard a well conceived and delivered execution of the design, that is all. There are reasons that I made the statement that I think it was amplification problems on both occasions (mismatched, underpowered, questionable crossovers, etc.). I would like to hear a good pair.

I'm not trying to read too much (I hope), but I am curious.
It would be disingenuous to believe that the V1s do not use the Orions as a starting point. Alas this is reinforced by the unfortunate physical resemblance, but the basic operating principles of the bass and main panel are no different.
I've heard Orions, and variations of Orions, as well as other dynamic dipoles. And they all sound more similar than different, especially when compared to box speakers.
The chap who compared his Orions to the V! and Venuette here also noted an overall similarity, and I'd be very surprised if there weren't. Hence my surprise that you found the Orions so different to the V1s.
The use of the coax mid and servo bass isn't going to change the essential nature of such speakers.
My own speakers attempt to build on SL's work in much the same way as Danny's do. I also wanted greater dynamics and better bass. I also went with 12" bass drivers, but went MTM up top instead of a pro coax driver. And I use a different crossover and different amps. Because of this, SL doesn't consider my speakers an Orion variation (he thinks they are a Phoenix variation).
And yet mine sound very similar to the Orions I've heard, and indeed to the Audio Artistry Beethoven that sparked my interest in all this. Just with more bass and greater dynamics. I'd be surprised if they were that different to any other dynamic dipole like the Jamo, the NaO, the Arvo Part or the Emerald Physics.
Even the cheap center and surrounds I built sound more similar than different in spite of using different drivers.
Of course, I've not heard the V1s, although I have read the some of the other reports from RMAF. They could be radically different, but given the quality of the speakers I've mentioned I don't see how.
To me, the most interesting thing about the V1s is the use of the Servo bass units. Bass quality is excellent with the Orions, and with my speakers. But I'm sure it could be better and the servo system is an elegant solution. I wish it could solve the overall problem of bass quantity, but the laws of physics are somewhat unbending.
Sorry to be so long-winded, but your post made it sound like the V1 was a dramatically different speaker to the Orion, and I fail to see how this is possible given their similarities.
