OK, so I am not so crazy in trying to make an OB with foam core board. I ran across this thread: DIY Open Baffle Full Range Speakers from Wal-Mart . . .

I may be the first to try a line array in a foam core board OB

I HIGHLY recommend a hole saw for such a task. It can cut holes in foam board by hand, or use a cordless drill in reverse to control cutting speed. 76mm is about right for a 3" driver.

I can cut clean holes with an x-acto very quickly in foam core. I am afraid the hole saw will leave jagged edges and collapse foam at point of cut. You are right, there are a lot of holes but 2 minutes a piece is not so bad if I am making modular sections of 6 holes at a time. The real issue right now is WAF for such a large speaker at 6.5 ft and about 2 ft wide including wings.

Does "stacked" mean only three active horns per segment?

Bob,
We are talking about stacking modular open baffle foam core units with 6 drivers each. No horns here
This was all sparked by the sale on the 3 inch Aurasound drivers for $1ea if you buy 50. I thought it was a cheap way to experiment with a wall of sound approach of line arrays.

Speakers at Dollar Store - or are you talking about the foam boards? I was asking about the $50 speaker deal.
