Power & Performance

• Design: 6-driver, hexagonally opposed sealed enclosure, vibration-canceling architecture
• Crossover: Low-pass filter, variable 35 Hz – 150 Hz (with bypass option)
• Frequency Response (On-Axis): +/- 3 dB from 9 Hz – 260 Hz
• Frequency Response (30° Off-Axis): N/A (Subwoofer omnidirectional execution)
• Sensitivity (Room / Anechoic): N/A (Active subwoofer execution)
• Impedance: RCA: 10k Ohms; XLR: 20k Ohms
• Low Frequency Extension: 7 Hz (DIN)
• Suitable Amplifier Power Range: N/A (Active design)
• Maximum Input Power: 4,500 Watts RMS / 9,000 Watts Dynamic Peak (When connected to a 240V line; 3,000 Watts RMS on a standard 120V line)
• Performance: The Paradigm Reference Signature Sub 2 is an absolute legend in the audiophile world, widely regarded as one of the most powerful, sophisticated, and physically devastating self-enclosed subwoofers ever constructed. This massive hexagonal titan bypasses traditional limitations by utilizing a direct-to-wall "Kilomax" Ultra-Class-D™ internal amplifier plant to unleash up to 9,000 Watts of peak energy across six custom 10-inch active drivers. It drops an unprecedented linear low-frequency column down to a seismic 7 Hz. It is the definitive choice for zero-compromise ultra-luxury home cinemas and absolute reference playback spaces, pouring out bloodcurdling SPL volume levels ($112\text{ dB}$ at 10 Hz) while maintaining studio-grade timing, pitch control, and lack of coloration.

Audio Features & Drivers

• Six 10-inch Active Long-Excursion RCR™ Bass Drivers: Outfitted with specialized mineral-filled co-polymer polypropylene cones featuring a 30% mineral matrix content to optimize structural rigidity. The six active 10-inch drivers move significantly more air than a pair of traditional 15-inch woofers.
• Vibration-Canceling Design Architecture: The six drivers are mounted in vertically stacked, perfectly opposed pairs across three faces of the hexagonal cabinet. Because the massive physical forces of the cones firing out are completely equal and opposite, they mechanically cancel out cabinet energy transfers entirely.
• 150-Pound Massive Driver Motor Total Weight: Each individual driver holds a 25.2 lb (10.5 kg) triple-stacked hard ferrite magnet structure with a balanced field geometry, meaning the internal motor systems alone contribute over 150 pounds of raw industrial muscle inside the box.
• 3-inch 10-Layer Long-Travel Aluminum Voice Coils: Wound tightly on high-temperature polyamide composite Nomex® formers. This oversized, heavy-duty voice coil configuration provides unwavering electrical tracking stability through extreme peak-to-peak cone stroke sweeps.
• AVS™ (Airflow Ventilation System) Die-Cast Aluminum Baskets: High-pressure cast-aluminum frames engineered with massive built-in cooling ribs to support forced-air heat dissipation during intensive, long-duration theater dynamics.
• Extruded Aluminum Center Heatsink: An internal central pole core that draws thermal energy away from the high-velocity, low-turbulence pole pieces, permanently preventing performance-robbing thermal power compression.

Streaming & Connectivity

• Direct-Connected™ Output Stage: The amplifier circuit completely avoids traditional restrictive power transformers, connecting the output stage directly to your home line current to deliver instantaneous energy delivery.
• Power Factor Correction (PFC): Employs an advanced power conditioner that actively shapes incoming AC line current into a continuous sinusoidal wave. This allows the sub to draw 95% maximum electrical efficiency from the wall while drastically minimizing noise feedback on your home's power grid.
• Universal Voltage Input Sensor: Features a smart power panel that automatically operates anywhere between 108V and 265V, unlocking its full 4,500W RMS capability when introduced to a dedicated 240V line.
• Opto-Coupled Inputs: Internal input stages use high-isolation optical links to decouple incoming audio lines from the amplifier block, entirely isolating the system from ground loop hums and pre-amplifier line noise.
• Anthem Room Correction Integration (PBK / ARC): Ships with a custom calibrated USB microphone to integrate with Paradigm's Perfect Bass Kit (PBK / ARC Genesis), applying heavy-duty mathematical algorithms to digitally smooth out standing bass waves or bloated room boundaries.
• Balanced XLR & RCA Inputs: Packed with a balanced premium 3-pin XLR input along with stereo unbalanced RCA inputs to bridge effortlessly into high-end multi-channel AV processors or classic stereo pre-amplifiers.

Comfort & Dimensions

• Bespoke Signature Furniture Cabinets: Wrapped in elite, multi-coat hand-polished premium wood finishes—including deep Piano Black, sleek Black Ash, and timeless Cherry wood veneers.
• Removable Heavy Foot Castor Access: The heavy industrial base feet can be completely unthreaded from the cabinet bottom, revealing standard castor-wheel insert threads to facilitate moving the unit across flat floor boundaries.
• Overall Dimensions: 24.5” (62.2cm) Height x 23.75” (60.3cm) Width x 22.375” (56.8cm) Depth.
• Unit Weight: 230 lbs (106 kg) each — A back-breaking, incredibly dense cabinet mass reflecting the 150 lbs of internal magnets, thick multi-layered wood shell, and machined aluminum structural plate.
• Non-Removable Sonically Transparent Grilles: The cabinet faces feature integrated, low-profile black cloth grilles contoured to seamlessly wrap around the hexagonal cabinetry lines to protect the dense radial driver matrices.

Design & Build

• Central Pole-Brace Enclosure Matrix: The interior of the heavy hexagonal structure is fortified by a massive vertical pole brace that bridges the top and bottom panels together, forming an unyielding physical vault.
• Machined 5/8-Inch Aluminum Face Plate: The massive rear plate amplifier is machined from an ultra-thick 5/8-inch slab of aluminum, serving as both a robust structural spine and a massive thermal heat-sink panel.
• 10-Microsecond Short-Circuit Shielding: Outfitted with an ultra-fast digital safety relay that monitors output pathways, shutting down active operations within 10 microseconds if an electrical shortcut or thermal emergency is triggered.
• Hand-Built in North America: Fully conceived, engineered, simulated, and masterfully hand-assembled under rigid quality controls at Paradigm’s premier laboratory headquarters in Ontario, Canada.
