The Matterhorn may be physically smaller, but it's output would easily surpass this built in sub (And it's portable!).

Bit worried about that drum kit in his room.
A drum kit is the very last thing I would want in my listening room since they rattle A LOT once you play some music.

A bit old news. Still cool never the less.
And as Mavo said.
it has been out done by the Matterhorn. How much SPL at 8 Hz to cause an earth quake?

You cant just say "it goes lower" without mentioning its maximum spl at the low corner, since even a little dome tweeter can be fed with a 1 hz signal and has to have a tiny amount of output this low (since it will move from the 1hz wave).

The unspoken benefit of the rotary subwoofer is that for its output, it literally sips power. They can pound all-day-long at maximum output and never suffer power compression. One of these in a building is ridiculous. Two, mounted to the end of a 55 foot shipping container, could be considered a weapon of some sort. Only caveat, it's good up to around 40 Hz, so you'd still need some kit to match it up to the tops.
here two mini subwoofer projects from me, compare to that one from royaldevices in Milano:
one arround 2000 liters vented chamber (2x Precision Devices PD2150) and one with 4000 liters vented chamber (6x Precision Devices PD184 complete wall separating)
more pics you will find on my website (click on "tiefbassuebertr" and "contact info and then the URL of my home page)

The only thing the same is the woofers. Everything else seems to be updated as of 2010. Besides, this is the guys listening room.
@ tiefbassuebertr
And what would you do with two pd.2450 ??? ;-)
Any recommendations ? Now I use one in a 365 Lit Bassreflex case.
Have another one. It comes in my new house. My living room would be about 50m2, (5,83x 8,48)
Maybe one on the left side of the front, another one on the right side.
Any good ideas?
thanks

I know this is an old thread, but does anyone understand what the 3 x A-DIMENSIONAL ACCELERATORS is? 😕
What, you don't have any equipment to accelerate the light moving through your S/PDIF interconnects, thus having it travel through time in a specialized pocket dimension at the center of a power triangle (where the quantum shift happens,) which enable playback of the original sounds before any distortion could be added by the recording process?
Me neither, but that's about all I can make of this thing. 😀 That thing is low tech compared to the bag of rocks you attach to the interconnects from another outfit though.

Long ago, I was reading a book about sonic booms. The research group built something that looked like an acoustic isolation booth - in reverse. Had a big number of woofers along the surface in order to create sonic boom experience inside.
Now THAT is serious bass.

If you want to talk sonic booms there is always Georgia Tech's Sonic boom generator designed by Tom Danley.

Right! That's what I need to play Danley's fun test record with trains, bikes, and fireworks.
Thanks for write-up. Funny thing, talking about all this philosophy of getting Carnegie Hall faithfully into your living room (ha, ha), not an issue when talking about sonic booms in your living room because that is their authentic home in the first place.
(I was reading that sonic boom book I mentioned in my post... about 40 yrs ago.)

The more I read around this royal device site, the less impressed I am. Full of snake-oil and ridiculous claims of grandeur, reminiscent of the Affordable Valve nutter. My favourite (other than the quantum accelerator) has to be the SUPER EPIGENETIC internal cabling and external connection.
Out of interest, does anyone understand how you can make an amplifier with no active components, driven only by transformers? That's the claim here:
