DJK-

I had posted that info for Presto in the "Speaker" asylum a few days ago. Sorry you didn't see it. Here it is again:

"First, thanks for all your help. Now, in answer to your questions:

One rear port, 5" deep, 3.25" in diameter.

Also, regarding the cabinet's opening for the driver itself, the driver opening is 10 7/8" in diameter. The driver is approximately 12" across at maximum width.

Hope this helps."

By the way, the 'driver opening' I referred to in answer to Presto's question was the actual hole that the basket and magnet fits through into the cabinet's interior chamber. The driver itself is 12" in diameter from the outer edge of the driver flange across to the opposite outer edge of the driver flange. There are eight holes for fastener screws around the flange. The driver weighs a good 15lbs, so it has a very heavy magnet.

That should do it. Please let me know if I can provide any other assistance. To the extent I can, I certainly will.

Thanks again.

Cheers,

WS
