The Best Subwoofer in the World, Period. The most difficult task in designing SUB 1 and SUB 2 was not just to have these subs play lower and louder than any other subwoofers in the world, but to do so in a size that wouldn't dominate the average living room, and in a cabinet that could be mistaken for a very fine piece of furniture.

And then there are the mind-boggling specs. SUB 2 plumbs the depths to 7 Hz with bloodcurdling output: 112 dB at 10 Hz, 126 dB at 60 Hz (in room). Connected to a 240-volt line, SUB 2 delivers 4,500 watts of continuous RMS Sustained power and a Frankenstein 9,000 watts of Dynamic Peak power through its unique Power Factor Correction system. Talk about bringing your music and movies to life! SUB 1 is no slouch either, delivering 1,700 watts of continuous power and 3,400 watts at peak.

With not one, but six cutting-edge drivers in each sub, transient information is conveyed with pristine clarity and perfect precision. Dynamics come through with lightning-fast speed and a power so shattering that it must be heard to be believed. Bass reproduction is eerily accurate and detailed, in large part a result of the unique Vibration-Canceling Design Architecture (VCDA)


For more than 30 years Paradigm has set the standard for sonic excellence in every product category we offer. Our focus on providing the best in performance and value continually pushes the boundaries in speaker design. Stunning accuracy, a spacious soundstage with pinpoint localization, powerful, well-defined bass and thrilling dynamics are hallmarks of Paradigm's advanced speaker designs.

Vibration-Canceling Design Architecture
Physics trumps mechanics with a little help from Paradigm
Typically, subwoofer enclosures contain one large driver. As that driver moves back and forth, the cabinet can vibrate which leads to smeared response, bass that lacks clarity and definition. Well-executed cabinet design, like that on Paradigm Reference subwoofers, typically includes sophisticated and extensive physical bracing inside the enclosure.
So why, when Paradigm puts six drivers in a single cabinet without significant physical bracing, does a martini set on top, while the subs are playing, barely elicit a ripple? Designed, engineered and manufactured by Paradigm in North America, SUB 1 and SUB 2 are movers, not shakers … massive air movement, massive output, virtually vibration-free.
Six identical, perfectly balanced state-of-the-art drivers are radially aligned (two on each side) inside the cabinet. As opposing forces of equal magnitude, the powerful vibration-reaction forces (see the arrows in diagram, below) effectively cancel each other out. Barely a ripple disturbs the martini placed on top of the cabinet, such is the degree to which unwanted, distortion-inducing vibrations are reduced.

These Subs are Movers, not Shakers
Massive Air Movement
Massive Output, Vibration Free
Our Vibration-Canceling Design Architecture is only part of the story. There's still no replacement for displacement: In a small, compact form factor, six 10" drivers in SUB 2 move more air than a pair of 15" woofers! SUB 1's six 8" drivers move as much air as two 12" woofers. The other part of the story lies in the cutting-edge design of the bass drivers.

State-of-the-Art “Kilomax” Amplifier
3-Kilowatt Amplifier Platform. Designed, engineered and manufactured by Paradigm in North America, the SUB 2’s state-of-the-art Ultra-Class-D™ amplifier design premiered to rave reviews and great success in the Signature SUB 25. Motivated by their success, our engineers went back to work, tweaking, testing and modifying the ampifier’s circuit board and software. The result is the most powerful subwoofer amplifier we (or anyone else for that matter) have ever produced. We call it the “Kilomax” design because when connected to a 240-volt line, it delivers a monster 4,500 watts of RMS Continuous power and a Frankenstein 9,000 watts of Dynamic Peak power.

The simple fact is I couldn't stress this product in any way. You will reach the limit of what you think is sane far sooner than you will find any limit in the Signature Sub 2. It's an absolute Reference Status subwoofer, and I love it.

Dave Upton, Home Theater Forum

The SUB 2 is insanely expensive, unreasonably heavy, and all around ridiculous in almost every way I can imagine – and despite all that, I love it. It is a subwoofer that throws the entire concept of ROI out the window and is a testament to what engineers can accomplish given free rein to innovate. While I certainly can’t afford one – the SUB 2 deserves to be on the short list of anyone who can. It’s big, it’s a little stupid, and it’s the best commercial subwoofer I’ve ever encountered.

John E. Johnson, Jr., Secrets of Home Theater and High Fidelity

Paradigm has achieved their goal of designing the best subwoofer available on the market to date...The SUB 2 is in position, ready and willing to take on all challengers.

Josh Ricci, Audioholics

Most of my friends have seen so many speakers come through my house that they barely get a second glance or draw a comment anymore. Not the Sub 2, it invariably received comments and questions. Paradigm’s Signature Sub 2 is undoubtedly one of the most impressively engineered powered subwoofers on the market today. If this fine subwoofer is within your financial means you would be remiss to not give it an audition.

Shane Buettner, Sound & Vision

I’ve never heard a sub that approaches the performance of the Paradigm Reference Signature SUB 2. This is 230 pounds of pure, pulverizing home theater excitement, and it earns my highest recommendation. Unlike other subs, you needn’t worry about whether your associated gear is up to the challenge. With this one, you need to be sure your house is structurally sound enough to withstand it.

The Absolute Sound

The Paradigm SUB 2 may be one of the few subwoofers that can be properly mated with planar loudspeakers. Its lightning speed and ability to project front, rear, and sideways mean that its presence and positioning are simply impossible to detect. The SUB 2 features what Paradigm calls Vibration-Canceling Design Architecture, and the design clearly delivers the goods. The hexagonal cabinet can make it hard to install, but once in place the SUB 2 can deliver a crusing 112dB at 10Hz.

Tom Jung, Everything Audio Network

Within the first couple of seconds of that first depth charge explosion, I knew the SUB 2 was a game changer. The entire room shook and the leather in the theater chairs flapped like they were in a giant wind storm... The Paradigm SUB 2 Reference Signature subwoofer may be the best-measuring, self-enclosed, powered home cinema subwoofer ever made!
