Hi TomHello Chop. Since Ron deferred to me here goes.
I have never tried setting up a pair of G2 AG horns so I don't know where the best place to point the tweeter would be for that series of speakers. The G3 has the drivers time aligned and the tweeter is really something special. The best place to point the tweeter is right at the ear canal. There is some fine adjustment to the exact location but in general is it pointed at the ear. I have the Trios set up this way and I set up the Duo GT's this way at the SWAF. Nobody complains of any brightness, harshness, hardness, shouty-ness etc. (I personally would not tolerate that type of thing anyway.) If anything, I would say the sound at the SWAF was a little too soft. I was using the iTron amp at the SWAF and used one of the switches in the back to boost the tweeter output by 1.5dB to give it more liveliness.
One track I repeatedly played at the show was off Hilary Hahn's Eclipse album. Track 1-- Dvorak Violin Concerto in A minor: Allegro Ma Non Troppo. This is very aggressively played violin and she plays very high. The high notes have beautiful harmonic development and the vibrato is fabulous. I could play this quite loud without any issue. I had one Japanese lady sit in the main listening chair for the entire performance. Done wrong and this is going to be screaming at the listener and one would hurredly reach for the remote to turn it down.
Some may think that with the tweeter pointed right at the ear that is going to equal "head in a vice" type sound. This is not the case. All kinds of people came in to listen -- tall and short and sat in the same chair. It was all good. You could move your head around without the sound dramatically changing. Ron can comment on this. When he was listening to the Trios I specifically asked him, "Do you feel like your head is in a vice?". His respnonse was "Absolutely not!". But I will allow him to elaborate on his thoughts.
Thanks for the reply. Despite the age of my horns and my tweeters not being time aligned, that is helpful.
