Terracotta ... Off course Italians tried it
Ceramics - Terracotta speakers
quit nice looking actually
In Japan ... recycle car tyres
Here another one ... already thinking to do this for my sons room
On a guitar stand
How about a solid core door?
I built these to fit in the under counter space. I used a Crites Conscalla Type D package. Lined the inside of the opening with 3" rock wool and covered the front with hanging speaker grill cloth. They sound very nice to me with good bass response. The motor boards do not vibrate much.

We needed to make a clandestine stereo for use inside the Motorola plant during those late night sessions when there was no bosses around, or those there didn't care.
Home brew amps were easy, after all I worked for a company that made silicon. We made clones of all the Tiger amps.
Speakers? Well for drivers, about the only thing available was a pair of speakers stolen out of the ceiling tiles from the house PA system. Cabinets? We used a pair of the large styrofoam shipping containers that carried 100 bulk packed pagers (remember those?) These were the large Pageboy models, so the container was about 20 X 24 inches with inch thick outside walls. We just cut out all the interior dividers and sealed the box with double sided tape. These things sounded much better than they should have, and survived many hours of loud playing 70's rock music.
Rewind back to 1974. My friend rented out half of his warehouse to some guys that made waterbeds and bean bag chairs. I'm looking in their dumpster at all the discards......most people see trash, but I see......speaker cabinets! At the same time the guy I'm renting half a duplex house from is repairing the roof. He is ripping out plywood that has rot holes, but plenty of good area. I ask if I can have the scraps and use his table saw.......here is the result.
I made 4 of these at that time, two matched pairs. The black and blue pair were stolen a few years after I made them. I would wind up making a dozen or so in all sorts of color combinations since there wasn't enough material for several of the same color. Most had 6 X 9 inch car stereo speakers in them since they were cheap. I made a stack of 4 with guitar speakers for a friends band.
I have no idea where they all went, but I kept the two remaining originals until I had to start reducing the "stuff" collection prior to leaving Florida. I took these speakers out of my storage unit, connected them to a powerful guitar amp and beat them until all that 40 year old foam surround was scattered all over the driveway......then tossed them in the trash.
The box covering is bean bag chair grade Naugahyde. The grill covering is disco grade crushed velvet.....

You could have at least uncovered that engine for the pictures
Do this help any?

FYI: in the US we spell it "cinderblock". Sounds the same, and you never know if it is S or C, but this is C.
Cinder is lumpy coal ash. Old cinderblocks were pressed from "fly ash", mostly non-coal residue. Modern "CMU"s are pressed from various materials, concrete, ash, and aerated concrete.

"Sinter" is bringing powdered metals up very near melting and pressing firmly.
Yes, that price is very generous to the seller.
