The Dayton Audio SS12-22 Signature Series 12" Subwoofer is the ideal balance of compact size and serious output capability. Designed for high-performance sealed or vented systems, the SS12-22 is optimized for DSP-assisted sealed enclosures that deliver tight, accurate bass, while also excelling in small vented or passive radiator designs that extend deep into the lowest frequencies. With the ability to handle 900 watts RMS, this 12" driver is equally at home in demanding home theater systems, high-fidelity music setups, or car audio designs where space efficiency and high output are essential.

Rigid Cone, Maximum Control
At the front of the SS12-22 is a thick anodized aluminum cone, chosen for its exceptional strength-to-weight ratio. This lightweight yet rigid diaphragm resists flex under heavy excursion, maintaining pistonic motion across its range. An indexed edge strengthens the cone-to-surround transition, reducing unwanted resonances. A high-roll butyl rubber surround supports extreme excursion while preserving cone area, ensuring high output with low distortion.
3" Voice Coil with Advanced Cooling
The SS12-22 is powered by a 3" diameter, 4-layer copper voice coil wound on a vented aluminum former. The multi-layer coil increases motor strength and control by maximizing conductor presence in the magnetic gap, while the aluminum former pulls heat away from the winding for superior thermal management. Venting through the pole piece, sub-cone, spider, and coil gap ensures airflow keeps the system cool, preventing power compression even during extended high-output playback.
Optimized Motor for Low Distortion
To achieve consistent performance at all output levels, the SS12-22 employs a triple-stacked, FEA-optimized magnet assembly that generates a powerful symmetrical magnetic field around the voice coil. This ensures identical forward and backward cone travel, keeping distortion low even at maximum excursion. Precision-machined plates with sculpted edges maximize magnetic transfer, while an aluminum shorting sleeve, pole cap, and top plate ring maintain linear inductance. These motor refinements extend clean response into the midbass region while minimizing non-linearities and intermodulation distortion.
Consistent Performance at High Excursion
The SS12-22 features a dual spider suspension spaced widely apart to maintain cone and coil alignment at high excursion. This design eliminates rocking motion, preserving pistonic accuracy under demanding conditions. For durability, stitched tinsel leads are integrated into the top spider to prevent fatigue and eliminate unwanted contact noise. Together, these design choices ensure long-term reliability and stable operation even when pushed to the limits.
Power, Control, Flexibility, and Reliability
With its balance of compact enclosure compatibility, high power handling, and precision-engineered components, the Dayton Audio SS12-22 Signature Series 12" Subwoofer is the perfect choice for sealed or vented designs where both output and accuracy are priorities. Whether anchoring a home theater, enhancing a high-fidelity music system, or pushing a powerful car audio build, the SS12-22 delivers the low-frequency authority that today’s listeners demand.
Note: The SS12-22 subwoofer is a dual voice coil driver with a 2-ohm impedance per coil. All parameters are measured with the voice coil wires in series, resulting in a single 4-ohm load.
