Rigid Cone, Maximum Control

The SS18-22 sets the standard for strength and precision with its thick anodized aluminum cone. This lightweight yet incredibly rigid diaphragm resists deformation under extreme displacement, ensuring clean pistonic movement even at maximum excursion. An indexed transition between cone and surround provides additional edge stiffness to resist deformation and minimize unwanted resonances. A high-roll butyl rubber surround complements the cone, optimized to allow extreme travel while maintaining more consistent effective cone area.

3" Voice Coil with Advanced Cooling

Powering the SS18-22 is a 3" diameter, 4-layer copper voice coil wound on a vented aluminum former. This design maximizes windings within the magnetic gap for stronger motor force while keeping the gap tight for precision. The heavy-duty aluminum former acts as a heat sink, drawing heat away from the coil to maintain thermal stability. Combined with extensive venting through the sub-cone, spider, pole piece, and voice coil gap, the SS18-22 resists power compression and handles an impressive 1,300 watts RMS with ease.

Optimized Motor for Low Distortion

At the heart of the driver is a massive, FEA-optimized, triple-stacked magnet assembly that generates a powerful and symmetrical magnetic field. This ensures identical forward and backward cone travel, minimizing distortion even at the limits of excursion. Precision-machined plates with sculpted edges maximize magnetic transfer, while an aluminum shorting ring, huge pole cap, and shorting sleeve work to linearize inductance across the entire stroke. The result is reduced distortion, tighter control, and extended output into the mid-bass and upper bass ranges.

Consistent Performance at High Excursion

To guarantee linear cone movement and eliminate rocking, the SS18-22 employs a dual spider suspension spaced widely apart for maximum stability. Stitched tinsel leads integrated into the top spider enhance long-term durability and eliminate the risk of slapping against the cone or suspension during high-excursion operation. The combination of dual spiders and precision motor control ensures linear pistonic motion even when pushed to its limits.

Power, Control, Flexibility, and Reliability

With its uncompromising design, robust construction, and cutting-edge engineering, the Dayton Audio SS18-22 is a subwoofer built for enthusiasts and professionals who demand the very best in low-frequency performance. Whether used in a high output vented design or compact DSP assisted sealed system, it provides the power, accuracy, and durability needed to anchor any system with authoritative, room-shaking bass. The SS18-22 proudly represents the next level in Dayton Audio’s Signature Series—bringing together innovation and performance in one formidable driver.

Matching Passive Radiator Available

Matching passive radiators are available for all of the Signature Series subwoofers. For the flagship SS18-22, Dayton Audio offers the matching SS18-PR 18" high-displacement passive radiator, making it possible to achieve ground-shaking extension without resorting to giant ports that are difficult to implement in real-world cabinets. By using a passive radiator system, you will unlock the full potential of this 18" driver, delivering room-shaking bass with greater efficiency, zero turbulence, and uncompromising clarity.
