Hi Melotheory,
Did you consider a dipole full range line array, on a really thin 4" OB, with about 20 of your 3" FR drivers on one side, equalised flat to 80-100Hz and high passed 80-100Hz, with separate monopole/dipole active bass unit. It could offer all the polar benefits of a dipole, no box as opposed to omni, but likely greater image depth than the omni

Hey Joy....
To me, line sources are about dynamics and front row concert presentation.
I actually had these drivers in a focused dipole array. It's the "Event Horizon" thread.
The only way I would do a 4" wide dipole would be in a 7' tall focussed array. And I may do that some day.
I just want to finish this one as an omni, then I'll move on to the next obsession

Not really, Beveridge had products as omni line arrays already very long time ago. They were half space omnis placed on the side walls.

You sure are a lucky man to pursue your hobby unbound !!
Is the ambio processor good for both monopoles and dipoles in combining stereo signals.

Yeah but they were not full range driver omni's using acoustic reflectors. That was the whole point of these, to see if it helped with CTC spacing comb filtering.

Well, it definitely works great with dipoles and with any type in the near field.
You just need to be careful of reflections in the far field. I'm still investigating. On this flooder, it doesn't really help or hurt it. It sounds like you are in well either way
But, I tell ya......its far superior to stereo when set up correctly.

You may also like to try the matrix with 3 separate speakers. It depends less on the room geometry than single speaker stereo SSS.

How are you tackling comb filtering issues on the array, or are they too insignificant with such small drivers.

I'm going to use acoustic reflectors pictured here in the first post.

Omni full range line array???

If you want to know the excursion/dB output vs low frequency limits of any given driver or number of drivers, this online calculator is useful
