Do they sound better than wood or other enclosures?
Follow Ups:
Granite is not going to resonate much. It might sound a little lifeless in the mid-bass
Remember Rauna? They made speakers out of concrete that looked like periscopes. Heard them in 80's at a local shop.
The Thiel CS7 had a concrete baffle but it was heavy and prone to cracking. They changed material in the CS7.2. I think the Thiel CS6 also used concrete.
Denser than granite, with much better anti-resonance properties. A bit more expensive, of course, at $4.7 million a pair.
Shame they're so butt-ugly, though. I can see how the baffle shape minimizes diffraction, but the squashed booger look just doesn't do it for me.
You announce a fictitious product, something so outrageously overpriced that you don't have to worry about anybody actually wanting to buy it, but with something unique unique about it, some sort of hook. That way it gets reported on and spread around the internet, getting your name out there and driving traffic to your website where you can get people to look at your actual products.
This example of clickbait is even more ridiculous than those "Linn Audio of NH" behemoths we saw 8 or 10 years ago. He's got a full range Tannoy concentric driver there but with a $30 Vifa used as a supertweeter? Made with more gold than a small startup company could possibly afford to buy, and placed on... generic bar stool stands?
But I'll admit, I took the bait. But the original website is defunct. If you search for Hart Audio now you'll end up at the website of somebody who sells reasonably priced headphone cables. I don't know if it's same guy who used to make speakers, because there's no contact information on the website.

I guess you never heard of Narco Drug Lords?
Or Middle Eastern oil royalty?
Both types could literally burn $1000 bills in their fireplaces every night and never even notice the difference in their bank accounts.

Of course there are fantastically wealthy people around, but nobody is going to be fooled by such a blatantly fictitious product. That image is a joke. Besides, who leaves > $4M of solid gold sitting around in the middle of their house begging to be nicked?
"The low-end frequencies coming out of the speakers are the result of a unique innovation and help
control the bass wonderfully and give the music a realism that no other speaker in the sound
reproduction universe has ever achieved."
That's a million dollar sentence right there.
The bronze version is (was?) only $62,000.
Equally as fugly.

Similar look to the gold ones, but less squashed. Sort of like baby shmoos.
Remember the Shmoo characters by Al Capp.

There's a balance between a rigid box and a rigid resonant box. Granite is an excellent conductor of temperature and vibration energy.
Seems the best stuff to make a speaker box out of is still the humble, yet cheap MDF particle board. Dense enough not to resonate and still absorb vibration while not transmitting it.
I wonder why no one ever tried a speaker cabinet make out of softer dampening material, maybe thick neoprene, with a framework - either external or internal - to support the drivers and the soft absorbent surrounding material.
If JA put his accelerometer on it, the measurement would be zero.

Acora Acoustics speakers sound like LIVE MUSIC ?
have you ever seen these?
Is the bottom enclosure too small?

they're not my project, but probably not for that wimpy driver
I stumbled across the concept a few years ago ...
probably on AA

I lived with a pair of Eggleston's back in the day that had "stone" sides. They were marvelous.
My Eggys are still my main speakers and they still sound marvelous!
Granite provides rigidity and mass loading, but has no damping.
If you can think of a material, somebody has probably tried making a speaker cabinet out of it. In many cases, I think it's just to differentiate the product in the market rather than for performance reasons.
Cement (or concrete; i.e., cement plus aggregate) has been used more than once.
all the best,

AFAIK they are still using it for aircraft flooring :-).

I heard the small model at the Long Beach Show a few years ago and was mightily impressed by the big sound. Then I asked the price and realized for $15k that opens up a lot of potential competition so less impressed.
