That's not a sub, THIS is a sub — Deus Audio's 60-inch infrasonic bass driver is nearly 6 feet tall, can hit 8Hz, and handles 20,000W of power. This would be the ultimate home theater upgrade…

• The Deus Audio Invicta 60 is "the largest infrasonic subwoofer ever built"
• It has a 60-inch driver, and handles 10,000W / 20,000W peak of power, hitting as low as 8Hz
• At $170,000 (about £125,640 / AU$237,238), it's intended for high-end pro audio installations

Deus Audio appears to have created the subwoofer version of the giant speaker from Back to the Future that's so loud it throws Marty McFly across Doc's lab – though as a sub I'd be worried about this thing moving so much air that it might launch you into space or make your house implode.

The Invicta 60 is capable of putting out 20,000 watts of peak power through a 60-inch driver, delivering a low end that can reach under 8Hz, making it a sub that reaches deeper than an actual submarine.

If you're immersed in high-end audio you can become pretty blasé about spec sheets and price tags; this is a sector of hilariously priced HDMI cables and home theaters that cost more than homes. But I still gasped at the power of this sub, and at its price tag: the list price is $170,000 (about £125,640 / AU$237,238).

The good people of r/hometheater reckon it's "ridiculous" and in addition to having some fun with the idea of such an overpowered sub they point out that a similarly powerful speaker made by Mitsubishi in the 1980s meant that "people 2km away felt rumbling sensations."

There's no doubt that this is a sub you'll feel in your bones, even if you're nowhere near it.

Deus Invicta 60: key features

Deus Audio Machines says that the Invicta 60 "is not an evolution of subwoofer design — it is a complete rethinking of what’s possible in infrasonic reproduction."

It features a custom 60-inch driver, Deus' own MASS Drive motor system, a 20kW Class D amp with thermal and power monitoring, a dual voice coil design, and a customizable enclosure with optional weather sealing.

This isn't a speaker you can take home in the trunk: its shipping weight is 1,060lbs (481kg) and it comes in a crate roughly six by six by three feet. Unboxed it's 29.49 x 70.39 x 70.39 inches (749 x 1788 x 1788 mm).

It's not something you can stick on an extension lead either. As Redditor PonyThug points out, at 240v a 20K sub is going to draw "83.3 amps. That’s more than some houses total."

You might worry that such a big driver would be fairly slow and unresponsive compared to smaller subs, but Deus says that the bass here is delivered with "surgical accuracy".

According to Deus the Invicta 60 is "the largest, cleanest, and most accurate infrasonic subwoofer ever built — a reference for cinemas, research facilities, and anyone who demands the impossible." It's ridiculous for sure, but like so many over-the-top things, I love that it exists.
