Hi Keith and congratulations for your new babies... I'm truly jealous of your room size. Me too, as I previously wrote, assembled a VERY similar rig, vastly inferior to you welded supports, any, using the same approach: S-150, S-3000 and S-400, respectively mid-low/tweeter/mid-high. I fiddled for weeks, with several angles from extreme 110°, back to 30°, staying at about 70°... consider my listening room is ONLY about 25 square meters and I'm listening on the long side (see pix). The reason of my post is: yes, I took my time to toe in and out speakers, moving voices of some inches, trying to blend bass enclosure, flipping it 90°, playing with my Phonic gear to obtain a smooth emission fro each voice... BUT, all said and done at the threshold of my patience and interest for the thing, when I re-assembled the 4 ways in a more conventional way, I must admit... all my "new", "revolutionary" ideas in speakers positioning get tamed. It has been a quite entertaining, amusing, different audio adventure, but being at about 190 cm from the horns front, ears to horn-mouths, I'm sincerely enjoying a quite correct, musically involving, right in size and dynamics rendition... a sort of single speaker, a wide-band listening with much more air, details, trueness. Maybe, and I'm asking to Roman, am I too near to speakers to appreciate the full benefits of a different alignement (or whatever I experienced in the past weeks...)? With an horns mounting like Keith's I heard something not so cohesive, full-bodied... also details and center imaging were, in comparison to the actual rig, quite unfair to my ears, I can say now. I'm pretty sure that horns aren't only for large rooms: the best detail retrival I ever heard happened in my room and in another 20 sq. meters room... I recently measured with my (humble) Phonic PAA3 Audio Analyzer an SPL range between 40 and 98 dbV/A at listening position, with no pain at all, being able to chat with a friend without shouting. I'll sure won't stop experimenting, but that's what recently happened in my music room... maybe more traditional horns positioning someway "clicks" DPoLS-wise in my room, Roman? I don't feel me like I gave up in experimenting, BUT like I found a nice aequilibrium.

It is hard to me to comment at what you ask. It is like fishing fish. You can go to a beautiful mountain lake in go in a boat in open ocean. You can bring with you some sophisticated bate which was made with aim of the behavior of the specific fish you are targeting. You can bring good fishing equipment and to employ advanced fishing techniques that you might developed for years of fishing practice. You can study the fish manners and reflexes and you can make yourself to think like a fish if you wish. However, all you successes and erudition as a fisherman would greatly depend if you wish in the palace where the wish actually are. If instead of not-yet-polluted lake or open see you will go to fish in your local town’s sewer then no matter how good you as fishermen you will ketch nothing.

How that all relates to horns?

Well, horns are very problematic acoustic systems until they are implemented properly, too few people understand it.  One of absolutely mandatory attributes of proper horn implementation in my view is uncompromising and stubborn time alignment. To me to listen time-un-aligned horn is like fishing in that dirty sewer.  So, when I see picture, here comments or listen the time-un-aligned horn installation then people shell understand that I do not take it all very seriously.

You GOTO folks are in way hostages of GOTO’s systems foolishness. GOTO might do OK drivers but their ideas of system design is at the level of absolute idiocy. I do not know if it intentionally I do not think so. I think they just did not know better, I have some evidences of it looking at some steps they took, but I am not convinced, not do I care too mach…

Anyhow, all advanced techniques of shaping sophisticated image from playback are in my view available only in context of time-coherent system. To move, angle, tow-in, and fine time speakers where they the drivers are not time-align id like playing to better fishing line while fishing in Dupont’s waste sewerage...
