A hypothetical 'balloon' shape profile illustrates the power dispersion mounted square to the entrance hole in 2-D horizontal plane, typical of installations commonly seen. Multiple tweeters simply extend the range but do not alter the profile.
If two tweeters are angled from the central axis by 45 degrees in opposite directions. The resulting power dispersion is wider spread and more evenly distributed.
Furthermore I tilt the tweeters pointing skyward by another 45 degrees. This will reduce sound power projection to ground level.
The steel mounting strips are bent 45 degree backwards and positioned at 45 degree at the corner of entrance hole.
Visualize the intersect of 2 balloons in 3-D space. The space of volumetric intersection has extended range.
I prefer the twin tweeters - if one side fails, you still have 1/2 power.
