  • Tang Band 25-1372SC 1" Titanium Tweeter in Wave Guide

    I think someone recently mentioned this Tang Band tweeter in a thread regarding a waveguide,
    http://www.parts-express.com/tang-ba...eeter--264-858

    I'm curious about this and would appreciate any information regarding its performance in a guide. A friend suggested a concave dome tweeter might have some useful loading characteristics that might be beneficial compared to convex dome tweeters. I have some Epicure Air Spring tweeters I can try, but information on the TBs or other concave domes in guides might be useful.

    The nice thing about that tweeter is the built in start to the guide made right onto the flange. If you make a guide that simply starts on that same chamfer angle and then curves away gradually from that point outward, I can only imagine that it would perform quite well. What worries me about mounting an inverted dome behind a guide is that because it is inverted, there is a larger "chamber" formed between the diaphragm and an opening that might cover the surround.

      Just as an aside, I'm using that tweeter with the Santori 6.5 mid. I have not done any measurements yet.

        arlis,
        Would you like a guide designed as Pete suggests, to try? I'd be happy to design and mill one, two if you like.

          Pete, that's a good point, and worth exploring. I have no idea how this might work out. My friend suggested the concave surface might result in less reflection off the throat area surface, I think he was suggesting less reflection might produce "smoother" sound waves, more of a flow shaped by the guide rather than flow affected as well by reflections.

          Perhaps if arlis is willing, he can test some guides I've offered to mill consistent with your suggestions, and provide some useful data.

            I recently finished and temporarily assembled cabinets for this tweeter and NE180W-08 woofers. The tweeters are mounted in WGs and sound quite promising.

            I'd like to find another set of these tweeters, despite the flimsy connecting tabs TB provides. Unfortunately they are no longer available though through PE. Would anyone have a pair of these to sell?

            Thanks

              Here are links to photos. I could not remove the face plate so the throat required a thin wall to locate it at the depth of the surround. Were I to do this again, I'd use Aluminum at the throat rather than Corian, given the thin section, the Corian could easily have broken.

                Given these are no longer available through PE, does anyone know of a source for these tweeters?
