I definitely could have been more specific.
Narrow deep hall (40' x 110'), low(ish) ceiling at 12'
We don't do anything below 80 hz, so only need mid-bass coverage, no subs. I am sure about this, we run an 80hz high-pass on the mains right now in our other hall. It's a church, we don't do the rock-concert thing like some do.
The new hall currently has a single small flying line array front and center. Comfortably loud in front is nearly inaudible in the back. And the left and right front dead-spots are noticeable.
The plan is:
- mid-bass coverage from a flying center array of 2 DXR-12's side-by side (manually creating a 2x12 array).
Then three rows in DXR-8's separated like stereo speakers, maybe 10' from each outer wall.
The plan came from you guys (in an earlier thread), not sure which guys though.
The coverage won't be super even, but it will be better than the single flying center speaker we have now.
The theory is that bass (I don't know the cutoff frequency yet), carries much further than treble so I need a single point-source for bass, and can safely spread the treble out a bit.
So the mid-bass comes out from a center point source, and the treble comes from the three rows of speakers, each row time-delayed to match their distance from the front.
I expect we will need to add some sound absorbing stuff to keep all those treble sources from echoing around and making a mess too.
I was thinking of forgoing a DSP, but y'all convinced me that separate power and signal leads are best, the DSP's I am looking at have 6 outs, so a pair of those should do it.
