New Manifold idea......

[jeffp]

I'm trying to think outside the box. Bad pun I know. ;D

Anyway wondering if anyone has given something like this a try. Somewhat of a hybrid between a manifold and line array? Not sure how much acoustic output benefit this would have. I would think quite a bit as it's directing the sound into the desired area.

Have I lost my mind? The design isn't exactly what I'd do but it gives the general idea.

It will function as a line array no more no less.

Look at Paul W's setup you'll find a similar design.

Also please use only one thread per any specific project. That keeps info centralized. Creating a separate thread for each question confuses everyone.

The forum's software doesn't allow me to merge threads

Sorry wasn't sure this is something I would use in my project as the cost/difficulty to build it might out weigh the advantages it produces.

Looking at Paul's configuration it's still a square configuration using 9 drivers so 3 on each side makes since. What I was looking at was use in 4 or 6 total drivers either using 2 or 3 on each side of the triangle.

If it does function like a line array (you'd certainly know better then I) then it seems like the route to go as the opening doesn't have to be as large as a typical flat line array we normally see.

[ThomasW]

Either design has an overly small opening in comparison to a flat panel line array. The flat panel array will have the best sound since there's an opening as large as the Sd for each driver in the line.

Both Paul W's and your idea don't provide the benefit of mechanical canceling one gets from a manifold where the drivers actually face each other

Actually, this method will provide a bit of cancelation...

Assuming you've doubled the number of drivers, you'll only add 1.4 x the force pushing on the line array.

Not sure if it's worth it, but there ya go.
