Layertone,

That horn is reallt pretty! You need to get some clear 3/4-1" thick plexyglass to make the sidewalls from IMO.

Default Austin II...

Very sharp looking Layertone...... Is this a one off or could someone sign up for this experiment?

A few questions? And I'm sorry if they are kind of basic as I am trying to get up to speed here.
Do smooth radii for horns make any difference at all if the waves are wide ( I read that it doesn't matter on the web, but they look so nice.!....)

Dumb q #2...When MDF gets cut in fairly narrow width like that does it become brittle and prone to breaking?

What would the skin look like, or is that up to the creative power of each of us?

one more question..as far as resonance goes has anyone ever heard of a torsion box type baffle, it seems that might be good to decrease resonnance..... a link for the torsion box concept...

http://www.diynetwork.com/diy/shows_..._26946,00.html

So basically we would have a front baffle with two skins and a frame between the two. Thanks in advance for any help on this.

Default afew q...

1. You use vertical supports for the MDF, why not for the first path behind the driver? It looks like it may break there?

2. You are trying to keep the weight down, why keep those back triangles solid insead of hollow?

I'm kind of interested in this project for myself. How much would a pair cost?

Thanks in advance.

Default layertone question

R these cut with CNC router or CNC laser machine...

since these are all through cuts, it seems to me that a laser would cut the pieces faster and then perhaps more cheaply, with less dust, etc.
but I don't know about the imortant indexing holes.... a cnc routing station could probably just drill them but a laser would have to burn them ands that may not work.....

Default plywood...?

It seems to me that if say every third layer were cut out of plywood the final product would have more structural integrety? MDF, MDF, Plywood, MDF,MDF, Plywood?

Default I agree about the skin....

If one could get a nice finish on the layers independently so that they could be striped, or something than it would be very cool to have clear skin on the outside? How much would 1/2" plexiglass add to the total cost?
