Speakers with clay cabinets spotted

[EERecordist]

These are in Mexico. No more details.

 

[OldHvyMec]

Interesting.

 

[polmuaddib]

Awful looking. And it would be so resonant.... What a bad idea.

 

[Newman]

Ouch. A new low?

How do you know they would be resonant?

What a bad idea.

I am not sure it is a bad idea.
They remind me a bit of a transmission line.

One may not like the looks, but it is as clever as anything I have seen.
So I’ll give the Hombre points for that.

How so?

Awful looking. And it would be so resonant

What makes you think low fire bisk wear pottery has resonate problems? I worked in ceramics and pottery for over 57 years.
The density of the material is directly proportional to the heat used and material used during firing. Added materials like copper,
lead, salt (s) and particulate size in the clay all add to the difference in how the material reacts to heat. Most bisk ware has enough
strength the be pounded by 250hz and below without fracturing. Above 250hz there isn't going to be high enough sound pressure
to cause structural problems.

If the pottery was made by throwing the pot, coil pottery or slab pottery and was joined with slip, there is a good chance the coiled pot
would have a very high dampening factor by design. Spray a material inside like @Felx-Seal and it will be better than most denser
wood product and stronger than most MDF products. Once again, high quality MDFs can be extremely expensive and breathing
protection is required to work on either.

Corian is a great material much like slate but both are extremely heavy and slate is a sedimentary formation, not known for strength.

I've used several blends of different materials with grout, including wood, rice, plastic pellets, fiberglass, steal wool, copper wire,
aluminum filings from lathe work, fluffed the mix before pouring into wooden, plastic (pvc), poly vinyl, and rubber molds. Some of
the materials are very light because of the mix and when combined with accordion paper of different thicknesses and finished
with an epoxy/grout glaze, it offers a beautiful finish once assembly of the final cabinet in done. You can polish the finished glaze
and if color was added to the glaze you'll never have to do anything but dust and wax the cabinet.

As far as ugly, put a sheer curtain in front or turn the tubes vertical and add driver holders horizontal.

The world of grout, ceramics and two part have given us the tiles on the space shuttle and added considerable strength to thousands
of retrofit project all over the world, from the Bay Bridge to the leaning tower of Pisa.

Interesting stuff with a little history to back up what they have accomplished in the last 2500 years with pottery and grout mixes.
The last 100 years has produced thing like @Corian. That is some really cool stuff and very easy to repair and work with. A few very
high end cabinets have incorporated Corian as a baffle.

I built two sets of cabinets for DIY and used a @Corian front and rear baffle. Both Planar/Ribbon hybrid LS cabinets. The real trick
is not getting poisoned working with the dust from any of the materials used. I'm pretty sure MDF is the absolute worst, even
worms won't eat the shit.

I think it's great, maybe not hifi but very imaginative. We don’t know the context and the details, maybe the inside is heavily lined or even just with clay that does not dry. The top horn could be refined, the mid shape is strange but maybe it’s just for the support and 2nd and 3rd chambers are not used. The bottom « U » shape could be opened too, if cut low resonances should not be an issue.
Please update if you find more.

How do you know they would be resonant?

There's probably quite a bit of resonance in the steel frame work providing support. The clay probably isn't that resonant at all however.

 

[Zek]

Something similar ...

Marble 9

These are in Mexico. No more details.

To me they are looking like repurposed clay pots, but nothing wrong with that.
Twenty years ago I asked one artisan for a glazed ceramic enclosure made by exact dimensions. Price was OK, but I abandoned that project.

I have no doubt that you can make great solutions using ceramics in a way you described, but does this look like any high end application of ceramics and materials?
No, it does not.

You say, if it is ugly, put a curtain over it. Really? Why make something ugly in the first place? Function over form? I believe you can make better and nicer speakers in a simpler way.

And just because some designs are different does not make them superior. This applies to overpriced high end hifi as well as DIY stuff.
And you can see clearly this is a poor DIY job. This is not craftmanship.

I have no knowledge about pottery, I admit. So I can't be sure if this would ring or not. But, come on, this looks like Patrick Swayze and Demi Moore made a pot for fun. Just by looking at it, it rings...

Ok, but at least it might be interesting? If done right, maybe.

And finally, just the fact that we have absolutely no data about how it performs, neither subjective or objective, makes this design impossible to defend.

 

[Holmz]

Maybe it would be good for playing the “Adobe Bros” through?

Thought provoking: I played around with pottery making when I was younger and became quite fascinated with making and firing glazes and experimenting with mixing glaze materials into the clay, rather than merely using it as a surface application. I could imagine using molds and a slip process to make speakers with some interesting shapes and geometries finished with very attractive glazed exteriors.

I can't begin to guess how they would sound, but I give points for ingenuity / originality and overall look.
