On the Curve Sided Loudspeaker page posted a short time ago, the transverse lamination examples have flat baffles...
I want to incorporate this lamination method into my design but was wandering why the enclosures shown have stopped short of going for a full rounded baffle - which would have helped further reduce diffraction effects. Or is this incorrect?

Personally, I went as far as I could with the rounding. Just couldn't get round the fact that you need a flat surface to mount the drive-units to.
Other than that, you have to juggle height, depth, width and wall thickness to end up with the right volume.
Good luck with your Translams, Vikash. Post us any drawings or photos when you have them.

The downside of course are the sharp edges in front of the driver.
I guess I would have a short cylinder extending out to the frontmost edge of the curved baffle so the top and bottom of the cylinder would extend the same as the baffle but the sides would be a couple of inches long. Then mount the driver in the end of the cylinder. Inside and outside eggs seem the way to go....

It will be a problem overall in that case. I mean the tweeter will be mounted in a similar cutout.
The enclosure image was a bit exaggerated. The amount of curve would probably be kept to a minimum as it approaches the centre of the drivers, and so the edges won't be as pronounced.
I like the idea of chamfering. (Thanks for the image to pre-empt me asking what that is
) That might work well with the same exaggerated curve. Chamfering seems to be doing the same thing for diffraction but carved in the opposite direction. Any comments?Attachments
Bricolo,
I was wondering the very same thing. It seems to me from the
picture that Dave posted that on the midrange you would gain
some horn loading effect and on the tweeter the off axis response
would be a bit different across the horizontal plane.
The question is how much effect would this have on the sound?

There are some good words about the £5500 Caber on their site (but off course):
looks like a promising idea.
currently working on.....
a 6ft tall cone, (really a tapered quartewave pipe), the driver for this will be on a flat piece level with the surface at top and bottom and rounded neatly over to meet the cone as a smooth join , I hope !
(well actually, its now about 4' tall, and i keep thinking maybe I ought to get on with the rest of it one day
