In Reply to: RE: Does any one know if the out of patent Heil waveguide is being produced and sold? posted by Rafaro on June 01, 2017 at 07:51:49
Lots of people. You can get some less expensive versions at parts express.
My feeling is why not buy the Original from ESS? Imitations are not necessarily an improvement or cheapers.
ESS in California have 3 versions now, from about $319 on down.
I own 6 of the originals myself. It's tough to find a better tweeter that goes down to 1 Khz, or even 800 with a high slope network, active or passive.

Thanks but its not the tweet it´s a waveguide for a comp driver see patent. It started the linear array pandemic and it´s used by L Acoustics in their line arrays.
The picture does remind me of the Beyma driver in the link.
The Beyma´s external appearance is similar but the internals are diferent. The Heil waveguide is the only one that converts the circular output of a compression driver into a true planar wavefront for linear array use. All others Aproximate a true flat wavefront up to certain freqs. Surprisingly althought out of patent x 5 years it appears to be not yet mass produced !!!
