Paradigm Reference Statement SUB 1 Subwoofer
Hexagonal cabinet with multiple high-excursion drivers radially aligned in a Vibration-Canceling Design Architecture, patented built-in Ultra-Class-D™ power amplifier, sealed enclosure, PBK interface, removable grille.
SUB 1: The Best Subwoofer in its Price Range!
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. 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) …

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:
Mineral-Filled Co-Polymer Polypropylene Cones.
A 30% mineral content has introduced additional cone stiffness for a measurable increase in repeatability and consistency. Response is instantaneous—low, loud, fast and tight, unveiling layers and layers of low-frequency detail, with consistently perfect pace.
Overmolded NLC™ Non-Limiting Corrugated TPE Surrounds and Nomex® Cloth Spiders.
These extreme low-density NLC™ surrounds on SUB 1 were FEA-optimized and overmolded onto the cones in house. Ten times more effective than standard thermoplastic elastomers in damping vibrations and resonances, the corrugated material works in tandem with our Vibration-Canceling Design Architecture to ensure not a hint of distortion exists, even at peak-to-peak excursion (almost 2˝ / 50 mm in SUB 2!) and full-on output.
RCR™ Resonance Control Ribs.
NLC™ surround technology was not required in SUB 2 since the six 10˝ drivers already allow for larger surrounds. The cones’ resonance control ribbing simply reinforces the new VC design architecture. As in SUB 1 cone excursion on each driver is extreme.
1-1/2˝ (38 mm) 4-Layer Long-Travel Aluminum Voice Coils.
Wound on high-temperature composite polyamide formers in an oversize configuration, the coils provide exceptional stability and support for the extremely high cone excursion.
High-Pressure Die-Cast Aluminum Chassis with AVS™ Airflow Ventilation System Cooling.
Large built-in ribs increase the heat dissipation surface providing forced-air cooling during large musical transients and chassis convection cooling at all other times. CNC-machined to ensure a precision fit.
Magnetic Pole Piece:
FEA-optimized, tooled to support the extreme excursion.
Computer-Optimized Ceramic (Hard Ferrite) Magnet Assemblies with Balanced Field Geometry.
Using Finite Element Analysis, the magnet structures were optimized to yield the most powerful output in a Signature subwoofer to date. Transient and phase-response are exceptional with superb power handling and output linearity.
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.
