Mounting a driver on a curved baffle...

[The Paulinator]

I am making some wall-mount speakers using half-pipes of PVC, what is a good simple technique for mounting the flat driver frame on a curved baffle?

As far as I know there is no 'simple' way of doing this.

It depends on the size of the drivers relative to the radius and
thickness of the pipe, and whether the drivers sit under the
outside curve of the pipe, or subbaffle is used in front of this
surface.

What is the diameter of the PVC and what is the diameter of the driver?

A pity you are using wood as you can"cut and shut" creating a jagged curve then glue all thenwhen set smooth all down using a bastard or a sander. Either way seems laborious and you need a fair thinkness of wood to do it and all depends on the circumference and size of drivers used. Elliptical drivers ?

Wouldn't necessarily be an easy way, though, it would work. You could use fibre glass, and it would mould to the curvature that you'd like.

I'd be easy enough to cut something out on a band-saw, but it all really depends on what you want.

The pipe is 4 1/2" PVC, a quarter-inch thick. The drivers are 3" Tang Band 371's. I really want to mount them as flush as ****ible, if it IS possible. I realize I may have to have them a bit raised on a small baffle of some sort, but I still am hoping to find an easy solution, if available.

I know there is a company that makes heavy cardboard pipes for speaker building, I wonder what they have in mind for people that buy their tubes.

I had a go at this on some 100mm pipe;
I mounted the drivers on a flat baffle, glued some foam around the edges of the baffle, cut out a piece of the pipe to match the baffle, then screwed the flat baffle to the pipe.

With small drivers, you may be able to cut out an appropriately shaped mounting 'ring' from solid foam (the sort they use to line road cases etc); when the driver is screwed to the pipe there should be enough pressure to prevent any air leaks...???

I like that idea, except I might have the screws go through some little plastic or wooden cylinders before they go through the PVC, just so they are mounted on something solid. I worry that if I had too much foam between the frame and the PVC, I might have problems with an unstable mounting surface.
