Planet10,
Thanks for the impedance calcs. I think the 6 ohms with the 3x8 is probably a good compromise. I wonder if the DTA100 can handle 6 ohms?

45 and two rows staggered, what does that work out to?

If you want some fun with the Cornu, download Bruce Cockburn 'If I had a Rocket Launcher' or Jimmy Buffett 'Pascagoula Run' and turn it up.

I don't understand the 45 deg? Are you referring to line array? Melo Theory made a 45 deg flooder line array but no stagger.

Yes,
The [somewhat] pincushion frame allows you to turn them 45 to align them closer if you choose two rows.

Ok, that's 48 drivers per channel then, 96 total. I am getting carpel tunnel syndrome just thinking of all the crimping of the connectors! That can get real loud I bet. Have you ever made line arrays? Why do I bother asking a speakerholic, of course you must have! I will have to get that Jimmy Buffet song...

I have been day dreaming about building a 50 driver line array using a foam core open baffle cabinet with the $1 Aurasound 3 in neodymium full range drivers from Madisound. The drivers are $1 if you buy 50...
Is there a benefit to using foam core for an OB?
What about a BLH line array?
You could arrange it to be a front and back horn. Push-Pull.

The only benefit is that there is no sawdust and it is light and portable. I was thinking OB because of the extremely high qts of these units. Tell me more about push pull BLH.

Happy new year everyone!

Ok, I just looked at the parameters. Yup, OB.
You could do a push-pull, it would take a bit of eq. But it would be a great experiment, especially with such an easy construction method.
I would have to draw something on the vector program to give an example. I could do that tomorrow.
You will need eq for an OB anyhow, or any type because that driver doesn't have a rising response.
