I took the time to watch the video Hobbs posted. Danny, I'm really glad you enjoyed doing these so much! Your impressions in the video are exactly what I was trying to articulate years ago when we were standing in front of the S7s and you were playing with the toe-in on them for me. There's just a certain flavor of "right" this kind of speaker does that the OBs and the line arrays - for all the strengths the OBs and line arrays have that these lack - just don't do.
I'd be pointing anyone looking at the current classic monitor style JBL lineup, or folks into the vintage JBLs, or maybe even folks into the bigger Harbeths to look this way. $3K all in fully built is something that I'm betting could trade punches with a lot of speakers in that wheelhouse.
This is why one of my longstanding reference tracks is "Glycerine" by Bush. You can tell in the first 10-20 seconds if a speaker's got "it" or it doesn't.
If I ever get a room bigger than the X-SLS I've got now can handle, these are on the list.
