Piezoelectric Speaker KSN 1025B - Wide Dispersion Horn Tweeter (Beveled)

These are integral in the design for my Barking Dog Eliminator and work exceedingly well during initial tests. My poor dog was wigging out while I tested it inside (sorry Jax). And so far they are able to push high frequency tones with ease.

I purchased two of these. I think they sound good so far but I have not given a good test. Surprise when you make your cut-out! I'm making sealed box for 8" woofer, 2-way x-over with this tweeter. I measure cut-out from tweeter dimensions. Surprise! That big honking tweeter enclosure won't fit through it. See pic. So I have to make small adjustment to cut out. With this modification you can fit but you must take apart the tweeter. It's simple, just don't damage the diaphram. To install, I will first carpet the front face plate. Then, install the tweeter to the front face plate and I may install woofer as well. The enclosure will be completed such that I can just slap the front face plate on; actually it will be recessed an inch and a quarter. I may put back on last just to be able to carpet over the screws that I must put in front. Nevertheless, you want a small cut-out for your tweeter horn and you want to avoid making the cut-out modification in the direct middle because you have screw holes there. You can stuff some speaker putty or caulking around the cut-out in the inside after you attach the horn to your enclosure if needed. I think the horn looks good. My cut-out is around 2-inches wide and 6-inches long. Don't make the modification too big. I've never used horns like this so I didn't now what to expect.

Looks like it will do the job
