I have a pair of Lambda pro's that get very little use with Lambda sig's around. Again I am looking at the Sigma for their panoramic sound. I was looking at buying a pair but they
are not easy to find. I was running through Ideas to recreate the Sigma housing. So far my idea is to make a skeleton frame the same or really close dimensions to the original
using wood from a hobby store they make RC airplanes from. The Lambda pro drivers would be left on the aluminum plate and mounted in reverse to the wood skeleton.
The earpad side would be model plywood cut for the earpad opening and mounted to the wood skeleton. All other sides would have quarter inch square wire mesh and lined with
acoustic insulation same as original Sigma.
The idea is that the box of the original Sigma is not really all that sturdy and all the louvered plastic does not have to be there. It's the acoustic insulation on the inside that counts?
I think the idea of keeping the the drivers on the aluminum plate will be stiffer than the original and probably help the bass. Anyone think it is worth a shot or have any input?
