I picked up one a few months ago, driven by an eminence PSD2002 compression driver. Not bad, .. a bit "croaky" sounding down at the 1200 - 1600 Hz range, I'm not sure if its the horn or the driver's fault, (I don't really have basis for comparision) otherwise okay crossed over higher though I'm guessing any constant directivity built into it might de-emphasise the treble.

I have a pair but haven't built anything with them. They are not constant directivity devices - the walls are curved, not straight - so I'd be inclined to call them "horns" instead of a "waveguides". I was hoping for an inexpensive constant directivity waveguide.

If you'd be willing to cover the shipping cost, I'll give you my pair. Shoot me an e-mail if interested.

Appreciate the offer but I had the same hope as you.
Make some ashtrays, maybe?

Oh well, I guess my salesmanship skills are pretty poor if I can't even give 'em away.

Since a nice CD waveguide was what you were looking for, may I ask if you've found any elsewhere? I'm using the DDS 10" diameter, 90 degree CD waveguide right now with good results.
