However if you want some outdoor speakers for the winter time you could make them out of Pykrete.

14% Sawdust 86% water, by weight.
Pykrete - Wikipedia, the free encyclopedia

Those who watch Mythbusters know that they were once going to build an aircraft carrier from the stuff.

i have toyed with the idea of using phenolic birch ply which is used as insulating board in HV applications. Easier to work with than concrete, though only just since its a bit of a pain to cut. The benefit of fibrous plywood without the porosity.

Thank you for fair judgment of my tastes.

Actually, the shape of that speakers remind shape of this car: in that experiment I tried to avoid all possible causes of resonances.

Not cement but clearly an interesting and economical solution to wave diffusion.
These are papier mache from old console.

That looks like the paper cups on the backs of the midrange units in an old Cerwin Vega I've got hanging around here.

Phenolic Sheet is gorgeous stuff. The US dist. plywood is crap compared to what is available in Japan. I dream of having my perfected Open Baffles carved from canvas phenolic sheet 1" thick on a cnc machine...........One day......

This idea is more accessable to me, since my place of work has a machine shop for cutting, routing and profiling of phenolic linen, phenolic ply and grp sheet material. The cost of the raw stock is my main obstacle.
