I was looking at the MT121's TDA angle of the horizontal dispersion (20 degrees)and the angle of the side panel of the box (10 degrees).
If you put two MT121 side by side, won't that cause 10 degrees of overlaping of the mid frequencies==>combfiltering?
Should'nt they be splayed at an angle so no overlaping occurs?
I'm asking this because all the stacks I've seen with these, the boxes where next to each other.

I have mt121 with 60x40 horn and prefer to splay them with a divider  to get something like 40 degree angle between them... It is more related to the hf horn, so if you are using 90 degrees horns you'll probably need to splay them more.

You're right, the systems that stack like you've seen are wrong Smile
