Hi. I used to make the excellent Faraday low density concrete cabinet loudspeakers. I can still supply a DIY construction guide which may be of interest to enthusiasts as well as people generally interested in eliminating panel vibrations in loudspeaker design. I usually have something on eBay mentioning Faradaysound, but a member of this forum recently contacted me. So I thought I’d better join! Peter
Hi thanks for your message. I’m happy to answer any specific questions, but will find some information on eBay if you search Faradaysound or Faraday sound. Peter
I would be interested as well… not for loudspeakers thou (very much overkill IMO).
Can the concrete also be low carbon, or even the concrete developed to be a carbon sink?

I didn't even know there was a possibility of low carbon cement, yet it appears it already exists.

The supplies will probably be industrial, though.
P. S.: This thread reminded me that ages ago I owned a pair of TYR II which sounded great manufactured by Rauna of Sweden who was a pioneer in this.
The only thing I didn't like was that the tweeters weren't symmetrical, probably to reduce costs.
One thing I did was cut away all the excess wood that was sticking out around the perimeter of the speakers.
The black "protective" sponge was elastic and held up equally.
It also had the function of partly absorbing diffractions.

Cement manufacture is a major contributer to co2 emissions. Work is being done by the industry to combat this, but like all the massive industries their green credentials have to be inspected carefully?
