Concrete speaker cabinets

Following on from the comments about the cost of transport if manufacturers tried to produce concrete speakers I wonder if a double skin MDF cabinet would be possible? Then when you have them at home you could fill the gap with dry sand. Just a thought!

G.A. Briggs of the Wharfedale Wireless Works advocated sand filling.

I know this is an old thread but thought you might be interested in seeing the latest speakers I have in for restoration, they are Avance Concrete 190's, old Danish company.

I seem to recollect those. I recall Elipson made concrete cabinet speakers too.

I do remember those!
It was half a lifetime ago and I remember being in a crowd of folks at a show, almost all of whom were appalled at the thought of a white speaker of all things!
Personally, I thought they sounded quite good......

I think there's still a Swedish company making a range of concrete loudspeakers...Monolith or Monolit or something.

Back in the early '70s I knew someone who had built Kef Kit 3 (I think) speakers using concrete enclosures. The raw concrete was then (later)clad with veneered chipboard. The speaker stands were made from industrial Dexion strip!

In the late '80s a UK company called Faraday offered concrete speakers for sale. A collegue of mine at work had a pair. I never heard them so cannot comment on the SQ, but concrete does seem to be an interesting material from which to make speaker enclosures.

I also have a pair of Avance speakers but smaller pyramids and attached stands.. Actually use decent drivers, scan speak tweeter and err... Vifa mid bass? .. from memory. Keep meaning to sell them on but know I'll get nothing for them if I don't do them up (bits of paint missing, couple of chipped corners, tweeter baffle foam gone sticky as per all of those scanspeaks!)

Now some say you should go WITH the concrete vibe and show it in all it's glory! Saw a pair of these on ebay 6 months or so ago:
