a big toy to play with....

angeloitacare · 25th August 2008, 11:37 PM

Today i brought these big toys home.

I started the project to built the AudioVoice Eikon 4way hornspeakers in february. it was not a easy task. Many hours of work was necessary to build them, specially the midbass horns. I named them Eikon, what means " image ". That is the goal : to recreate and reproduce the most accurate image possible of the original event and recording.The next few days, when everything will be connected, and playing, i will know up to what point the effort was worth it.

some more pictures at my forum

Wow, that's crazy! How do you begin to plan something like that? What sort of math is involved? Are those exponential horns?

For the basshorn, i have choosen a expansion between expo, and tractrix.

the midbass horn has tractrix flare, however the curve at the mouth does not terminate with 180 degree, ( like regular tractrix horns ), but goes beyond, to give a shape similar to LeCleac'h horn profile.

The midrange horn has LeCleac'h profile, 60cm external diameter, the size is similar to Azura 340 horn.

the tweeter uses a proprietary wave guide.

the math, there is a lot of info at my forum, at horn basics section.

Probably will not sound good.
At least if you expect the original event like.

This is the nature of things.
We do not often get what we hoped for.
Still we will try again .... and again .... and again.

Until

That may actually be the most discouraging post I've ever seen on this forum

Those look amazing! Looks like the efficiency will be very high, you have plans to use low power valve amps with this? The drivers look to have high power ratings too though, with some big solid state amps this could blow you out of a room

. Sure it'll sound great and it certainly looks impressive.

I hope they sound good cause they have to be the ugliest speakers I've ever seen!
