Description

Paradigm Signature SUB 2 — 10″ High-Impedance Subwoofer Drivers 27.7lbs each! 6 Available.

Extremely specialized, high-impedance 10-inch subwoofer drivers sourced directly from a former Paradigm engineer — engineering-equivalent to the drivers used in the Paradigm Signature SUB 2, offered individually or as a complete matched set of six for advanced users only.

Paradigm’s Signature SUB 2 is one of the most ambitious subwoofers ever built, using six high-excursion 10-inch drivers in a sealed hexagonal enclosure, driven by a 3,000-watt Ultra-Class-D amplifier with power-factor correction and an unusually high internal rail voltage. To make that system work, Paradigm engineered drivers with very high single-driver impedance (approximately 50 ohms each) so that all six could be wired in parallel, presenting roughly a 10-ohm load to the amplifier — exactly what the high-voltage, lower-current 3 kW module is designed to see. These are not general-purpose woofers; they are system-specific transducers optimized for a unique amplifier architecture.

Each driver weighs approximately 27.7 lbs, reflecting a massive motor structure, long-excursion voice coil, and heavily built frame. In the production SUB 2, the driver array alone accounts for well over 150 lbs of the system’s total weight. The SUB 2’s amplifier runs from a roughly 400 V DC bus derived from a direct-off-the-line, PFC-equipped supply — which again underscores just how unusual the drive requirements are for these transducers.

Because of their very high individual impedance, driving a single one of these drivers from a typical home amplifier will only yield a few watts before the amp runs out of voltage swing and begins to clip. To get meaningful output you will need to:

Wire all six drivers in parallel to approximate the original ~10-ohm load, and

Use an amplifier with very high peak output voltage — such as a Paradigm SUB 2 amplifier module, or a powerful pro-audio amplifier (for example, a Behringer iNuke/NX 3000-class unit is specifically recommended by the engineer)

The 3000-series models are generally the better choice as they offer more flexible bridging options than the 6000. Alternatively, the engineer reports success using a 600-watt Class D amplifier feeding the secondary of a 600 W toroidal transformer, with the driver connected to the 120 V primary — effectively stepping up the amplifier’s output voltage for use below approximately 80 Hz. This is an advanced technique requiring a thorough understanding of transformer coupling and electrical safety; it is mentioned here only to indicate the kind of engineering knowledge these drivers demand.

These drivers are not suitable for typical plug-and-play DIY subwoofer builds. They are appropriate only for:

Owners of Paradigm Signature SUB 2 units seeking authentic spare or replacement drivers

Very advanced DIYers who fully understand high-impedance driver arrays, high-voltage amplification, and parallel wiring schemes

Experimenters comfortable with transformer-coupled or step-up driven systems and all associated safety considerations

Each driver has been visually inspected and tested for basic continuity and mechanical integrity but is sold as a raw driver, not as a finished subwoofer system.

About brand
Paradigm at Radique

Paradigm has designed loudspeakers in the Toronto area since 1982, with engineering roots that run through Ottawa: it took part in the National Research Council's loudspeaker research here, and its research lab has been in Ottawa since 1993. We've had more than 600 Paradigm listings so far, covering 193 different models, more than any other brand we resell. Every used Paradigm here is inspected, tested and serviced as required, then photographed in-house and covered by our Bumper-to-Bumper Warranty and Perpetual Trade-Back Program. Don't see the model you want? Tell us on First Dibs and we'll email you when one arrives.

Our five best-selling Paradigm models so far: the Cinema 330 v.3 on-wall speakers, the Mini Monitor bookshelf speakers, the Monitor 7 towers, and the PS-1000 and PDR-10 subwoofers.

The Paradigm story, 1982 to today

Jerry VanderMarel and Scott Bagby founded Paradigm in 1982 in the Toronto area, VanderMarel running sales and marketing and Bagby design and manufacturing. Their first speakers made their debut at a Toronto audio show that year, and Paradigm says 12 dealers signed on.

The Ottawa years. In the 1980s almost every major Canadian speaker maker measured its designs in the National Research Council's anechoic chamber here in Ottawa, and Paradigm took part in the research Dr. Floyd Toole led at the NRC, which paired chamber measurements with blind listening tests. Paradigm built its own anechoic chamber in 1988, sparing its engineers the five-hour drive to Ottawa. In the late 1980s and early 1990s it was one of several Canadian companies in the NRC's Athena project, which studied speakers that adapt to the room. NRC scientists Peter Schuck and Marc Bonneville then joined Paradigm, which says it opened its Ottawa research centre, PARC, for them in 1993. That lab went on to design Anthem's electronics and its room-correction system. A 1990s Paradigm Titan is now part of the collection at Ingenium, Canada's science and technology museums, here in Ottawa.

Growth. Paradigm moved into the US market in the mid-1980s, added its first in-wall speaker in 1989 and launched the Monitor series in 1990. The Titan was a hit by 1991, the Atom followed in 1992, and the PS-1000 of 1994 was its first powered subwoofer. By 1992 Stereophile counted about 256 Paradigm dealers in the US.

Reference and the new factory. The Reference line, with its Studio speakers, arrived in the mid-1990s; Stereophile reviewed the Studio/100 in 1997. In 1998 Paradigm bought Sonic Frontiers, which brought Anthem into the family. In 2001 it moved into a new Mississauga factory with what it calls the hemisphere's largest privately owned anechoic chamber, at 33,000 cubic feet. A tour that year found the plant finishing 1,500 speakers a day, with driver frames cast, cones moulded and voice coils wound in-house.

Changes of hands. Co-founder Jerry VanderMarel left in 2005, when the private-equity firm ShoreView Industries became Scott Bagby's partner; together they went on to buy MartinLogan. Compact lines such as Cinema were built overseas from the start, and from the 2010s Monitor was too, while Prestige (2014), Persona (2016) and Founder (2021) have been built in Mississauga. In 2019 Scott Bagby and his son John bought Paradigm, Anthem and MartinLogan back from ShoreView, and their company, PML Sound International, added GoldenEar at the start of 2025.

Which Paradigm is which?

Performance Series (1990s to 2006): the entry line, with the Atom, Titan, Focus, Esprit and Phantom. A 1990s Titan's label reads "Performance Series … Made in Canada". At the end of 2006 the Atom and Titan moved into the Monitor line.

Monitor (from 1990): the step-up line, and from 2006 the entry line; today's version is Monitor SE. In the early 1990s it was topped by the Studio Monitor tower, in real wood veneer.

Reference Studio (mid-1990s to mid-2010s): the Studio/20, 40, 60, 80 and 100 plus matching centres, with die-cast aluminium driver chassis and aluminium-dome tweeters, made in numbered versions. From the v.2 generation of 1999 the sides came in laminate or, for a little more, real wood veneer. A favourite here is the Studio/80 v.2, a slim 2.5-way tower from about 1999 to 2003; the pairs with real wood sides are the ones to find.

Signature (2004–2016): the flagship of its day, part of the Reference family.

Cinema (from about 2000): compact home-theatre satellites and centres in polymer cabinets, designed to be used with a subwoofer, later sold as Cinema CT packages.

Millenia (from 2006): slim aluminium-cabinet speakers made to suit flat-panel TVs. The little MilleniaOne was Sound & Vision's 2011 Product of the Year.

Stylus (from 1999): weatherproof outdoor speakers.

Today's lines: Monitor SE, Premier (2018), Prestige (2014), Founder (2021) and the Persona flagship (2016).

Subwoofers: from the PS-1000 (1994) and Servo-15 (1996) through the PS and PW series to Defiance (2018).

Buying used Paradigm: what to check

The rear label. Where a Paradigm was built depends on the line and the year, and some names were reused (the Atom and Titan moved from Performance to Monitor, and the Esprit name appeared in more than one line), so the label tells you exactly what you have.

Veneer or laminate. On Reference Studio models from 1999 on, real wood veneer sides were an option; look closely at the sides before you assume.

Woofer surrounds. Owners report foam surrounds needing replacement on some older models, including early Titans. Press gently around each one.

Powered subwoofers. The amplifier is the part most likely to have aged. Run a used sub at volume and check that auto-on still works.

Everything we list is inspected, tested and serviced as required here, and comes with our warranty.
