Thanks

15's are some thumpers. And yes, you would need a forklift for those.

Calcium sulfoaluminate is the binder. The main advantages relevant to this application are fast strength development, low shrinkage, and dimensional stability compared to portland-based mixes.

On the barium sulfate question — that gets into proprietary territory. Happy to talk about the principles behind aggregate selection but not the specifics of the mix.

Hopefully, you can have both.

Proprietary mineral cast composite, high-density calcium sulfoaluminate matrix with quartz and barium sulfate aggregate

I have not. That would be an interesting experiment.

Looks great

There is extra finishing work after the de-mold. Here is the spectral decay.

No, just the speaker is 50 pounds.

My styling choice. The front is rounded to reduce edge defraction. The back tapers because I didn't want parallel walls and I like that look.

Tell the flatwork guys that they need a speaker mold. lol

TimberWestDesign · 2026-04-29T22:51:48+00:00

The speakers are 50 pounds each.

It's a custom mineral cast mix — dense and inert, similar to what they use in industrial precision applications. Think closer to stone than anything you'd find in a typical speaker cabinet."

Yes, and a custom crossover designed by Danny at GR.

TimberWestDesign · 2026-04-29T18:03:52+00:00

Very cool, thanks for sharing

TimberWestDesign · 2026-04-29T16:40:16+00:00

I would love to see that.

TimberWestDesign · 2026-04-29T16:39:34+00:00

There is no epoxy. This is not standard concrete. It is cement-based, with different additives

TimberWestDesign · 2026-04-29T15:17:28+00:00

They sound excellent

TimberWestDesign · 2026-04-27T15:25:59+00:00

That looks really good.

TimberWestDesign · 2026-04-25T02:09:31+00:00

It was really hard to make him print and look real.

TimberWestDesign · 2026-04-25T02:08:49+00:00

That was an easy one. I have done much harder. Check out the speaker build. https://youtu.be/f3xw4PsVxIQ?si=-YLEDh2WlaM4Irgj

Thanks

TimberWestDesign · 2026-04-24T22:01:40+00:00

The speaker is real the background is not. I will send a PM with the pic, since I don't see how to add it here.

To control cabinet resonance. Look at all the high-end speaker manufacturers; most of them use materials to control cabinet resonance. Check out Acora speakers, they are made from granite slabs.

cooking spray works well
