Concrete Egg halfs

[macaroonie]

The problem with the 3114 network is that it uses the small autotransformer , probably very hard to find.
IHMO best to use 4313B 's ( Thats a name ) equivalent circuit posted above. Nice and simple

Hallo !!
The guy ho made these eggs only used a 5 mm plywood baffle !!
I`m building a new one in 25 mm MDF.
The drivers will be 2213 , 2105 and 2405.
The xo is still the biggest truble !!
Have started to pick the eggs apart , will send som pics !!

I'd go even thicker than 25mm, to allow for either a LARGE roundover or bevel around the perimeter. With care, this is not difficult to achieve. It helps with diffraction, improves imaging, and minimizes diffraction based comb filtering accordingly. It also would be a big visual enhancement to make these more egglike.

hello,
beautiful eggs but her are some warnings:

1- as said in this thread, the flat font panel is not recommended, especially on the edge. Since you have an egg, try to keep the shape at the maximum.

2- the shape of the egg concentrates the resonances on one point (one line here), try to put something at this point. Elipson which made round enclosures put divisions inside.

Best regards,
jean
