Back in end of 90s, we read articles by Thomas Dunker, Joe Roberts, Bruce Edgar, and many others (some of them were designers and some of them just publicists) who were trying to persuade that horns are some kind of advantageous topology and that...

The mouth of the left channel is done. Now it has the corners are glued in - you can see in the joins between the pans are chorded – you can see it on the first image. It is left just to finks beefing up the frame – you can see on the second im...

Here I would like to share some basic ideas about the skeleton of the horn. This is just a view from 50.000 feet but it will give some illustration what is brewing in my mind.
The one side of the triangular horn will be flat and will sit at le...

Well, I have to admit that I did not listen the whole sound of AC vs. DC filaments yet. I will bring home today my DC lab supply that I use for my electromagnet coil and will give the try. I still at this point am not concerned about the “whole ...

Hi folks. Who ever listened to Living Voice Vox Olympian Speakers might've liked them as much as I do.
They got a great realism in their projection. Some things are obvious, some even claimed.
Its claimed to use excellent drivers, high quality ...

Hi!
I just thought of something that could have some relation to this topic:
Take a horn with a driver, the driver produces a signal, the pressure wave will travel outwards more or less like a spherical wave front along the axis of the horn, think ...

Hmmm, are you sure that you do not do a mistake?

I have received some questions and criticism about tapped horns. In order to spread a better understand of tapped horns, I’ll restate the questions and try to answer them.
1.) The mouth of the tapped horn is too small to be useful.

Here, you can see the distance to front wall. The wall is about 10cms behind the moss garden.About 35cms to the wooden binary diffusors surface. Another 55cm to the drivers and total distance to front structural wall is about 90cm (2,95feet)Maybe mor...

Mani at al. I have a paid of zu druids. Running them with 15W amp (d-class) and it is not enough for high level, although it does better than you expect. The soundstage sensitivity measurement was 97dB, but their test did not load the driver correctl...

[quote user="jessie.dazzle"]Wow, 6 x 15" drivers (!!!); though the curved profile certainly imparts rigidity, I'm guessing this horn must resonate more than a bit (no bracing until the mouth) -- but I like this thing.
