some help pelase......

well...you see, i landed on a good driver for a 1x18 and am trying to make a box for it. Want to get as near as possible to the SWR one so would like, if possible......

the internal dimensions of the box and if possible the port dimensions too

I have tried to get the tech specs for the driver to enter into this greta program but alas had no luck.

Thanks for your help

Chris :cool:
 
What kind of 18 did you get?

The Big Ben is a simple box, probably made of 5/8 plywood. You can work backward from their published dimensions.

The ports are unducted holes in the back of the enclosure. Technically, the duct is 5/8 in. but there is no cardboard tube. They might be 6 in. in diameter IIRC. Also from examining one (IIRC), there are a couple 2x3 pine braces running horizontally across the back of the enclosure for stiffness.

I may have made a drawing...I'll have to check at home this evening.
