Tx for posting. Interesting folding.
I really like this "•Tapped Horn Subwoofer design (patent pending)" Pretty funny. |

Tom Danley has licensed a number of his techniques to VTC - the "patent pending" is Tom's patent.

Which drivers are they? Great folding, I've sketched summat similar but I would've never come up with the idea for those side panels that are slanted in two planes.

With the patent showing the true name of 'Tapered' horn rather than 'Tapped' |

Chas n Dave : it's like Drum and Bass but with beards. E=mc² ±3dB

In the bottom two octaves it really acts more like a tapered transmission line, not a horn at all.
In my opinion, this old patent should be listed as prior art on the Danley patent. It shows the basics of what he is doing.

I definitely dont want to stir up this topic again ...
I didn't know Danley was licensing the technology out to anyone. |
