So we have been busy over here in the countryside of Perth Ontario. Some things are a foot as it were. Some of them even useful. I'll put up a few pictures:

Some work on adapting a tweeter faceplate to our silk dome tweeter. It's a been a series of simulations, and prototyping of the simulations to get the desired effects. A dome tweeter on it's own is not really all that flat in frequency response. And the mount can have quite an effect on the final outcome. Our current tweeter mount for the car audio world was a quick and dirty version that is getting tweeked. It's response is getting a bit of a flattening as it were. The home audio version will be available in two versions a conventional 80 mm flange type and a larger waveguide/short horn. I'll address my definition of the difference between the two. I'll call something a waveguide if it only effects the dispersion pattern of a driver. It becomes a horn when it has an effect on the efficiency of the driver.

Now don't get your knickers in a knot. A horn need not be a dirty nasal sound instrument of torture. A poorly designed horn can fit that description. We have all heard them right? Compression drivers on rectangular contraptions that breathed fire in the name of high frequency extension. Not.

A properly applied horn especially with a hemispherical driver diaphragm can have a very undistorted output that has a rather well controlled on and off axis behavior. And it is to that stated goal that I aim to make a contribution.

Cars? Tweeters??

I thought you don't have any for cars???

Well I don't have any of the fancy aluminum cups and mounts. But this is an example of mounting the raw tweeter into an existing factory tweeter location.

The outside diameter of this tweeter is 35 mm. My American friends can bet on 1 3/8" with a little bit of fudging the hole. There are few of these available if you are interested. They will be selling at $95 U.S.D. per piece. The new tweeter mounts are being designed and I expect them in the first few months of 2020. If you are interested in existing raw tweeter stock drop me an email and I will ship them out to you.
