Dayton Audio Signature SS12-PR Passive Radiator

The Dayton Audio SS12-PR Signature Series 12" Passive Radiator is a premium solution for audiophiles seeking to elevate their subwoofer system with deep, controlled bass extension without the complexity of an additional amplifier. This passive emitter is ideal for custom speaker builds, home theatre setups, or high-fidelity stereo systems where space and efficiency are paramount. By replacing a port in a sealed enclosure, it delivers the low-frequency output of a larger cabinet while maintaining a compact footprint, making it perfect for DIY enthusiasts and professional installers alike.

Engineered with an aluminium basket and frame, the SS12-PR offers exceptional rigidity and reduced resonance, ensuring clean, distortion-free performance. Its 12-inch nominal diameter (304.8 mm) and 126 mm mounting depth allow for versatile integration, while the 8 mounting holes on a 302 mm bolt circle diameter simplify installation. Key technical specifications include a resonance frequency (Fs) of 25.6 Hz, an equivalent volume (Vas) of 77.3 litres, and a displacement volume (Vd) of 1568.4 cm³, enabling deep, articulate bass. The mechanical loss factor (Rms) of 4.47 ensures optimal damping, and the cut-out diameter of 285 mm accommodates standard enclosures.

This passive radiator is a robust choice for achieving seamless low-end extension, combining Dayton Audio's Signature Series precision with durable construction for lasting performance.
