Could it be that a 60X40 horn will naturally give more of a focused high end than a 75 X 50 box simply due to it's tighter focus???
 ... and thanks also for the quality photos.
It all depends on the ACTUAL pattern of coverage-not the stated number.  This will vary with freq. Many horns get pretty narrow as the freq goes up.  Polar plots or coverage angle charts are the best way to see how they actually perform.

If you look at the measured angles of coverage of many boxes you will find that the stated numbers do not even come close to the actual coverage pattern.

  And in order to actually have that pattern to a usable low feq requires a large horn.  The horn is the Noesis is larger than most and that is a good thing.

I have attached a very popular manufacturers measured data from a SINGLE BOX.  Notice how the actual coverage pattern varies quite a bit-depending on the freq.

60x40 Horn.

In that orientation, vertical oval throat, it's 40 wide x 60 high, no?

I would assume so.

Possibly, but since they're rotatable horns it's irrelevant. The real question is which orientation matches the lows at crossover best?

This is why it's relevant.

3TX HF pattern does seem to drop off in the horizontal off axis steeper than the 212s,

Dan, the horn is installed so that it is 60 degrees in the horizontal.

The vertical oval is the wide orientation? Interesting. Is there some sort of lens effect?

This is an update to using the 3TX speakers at a couple of gigs. First off I received the new enclosed-horn cabinets from Jeff, much more professional and finished look. The demos I had went to Dan, I will not speak for him, but do understand he is very very pleased with their performance.

One of the last gigs I had with the 3TXs was a pep rally in a gym. I had no apprehension bringing 1 3TX over 2 subs for this. The program consisted of ipod playback, announcements, skits, beat-boxing, speeches... and slam dunk contests.

Power on a single AC outlet, 2 PL236 bridged for tops, and one PL6 for subs. Max signal of -20db on amps. Tablet mixing from bleachers. System performed flawlessly - powerful, clear and loud presentation of all material. Notice mics were positioned out front of the stacks most times, but somewhat in the null - still, no feedback issues (AKG D5 mics).

The Noesis 60 degree pattern really helped direct sound on this setup (could have used 40 I suppose, but did not think to rotate horns). I would say at times it was could have actually been too loud. Everyone pleased, especially the boss (Coach Rob). Sometimes Im still surprised and impressed at the Growlers' performance, I could feel the floor and bleachers vibrate across the court on music tracks.

Best,
Mike

I don't think rotating the horns would have been good. Would have put too much sound on the ceiling.

Glad they are working. I am almost jealous. :-)

Dont be jealous, Im broke now.

Good point on the rotation, agreed, but it probably would not have mattered, considering the diffused field, but I still would have liked to have listened to both orientaitons.
