Dayton Audio Signature SS15-PR Passive Radiator

The Dayton Audio SS15-PR Signature Series 15" Passive Speaker is a premium passive radiator designed to elevate the performance of your subwoofer system. By replacing a traditional port or adding extra cone area, this passive emitter delivers deeper, more controlled low-frequency extension without the turbulence and chuffing often associated with ported enclosures. Ideal for custom home theatre installations, high-fidelity audio systems, or car audio builds, the SS15-PR excels in sealed enclosures where it can be tuned to achieve a seamless, room-filling bass response that complements any music or film soundtrack.

Engineered with a rigid aluminium cone, this 15-inch passive radiator offers exceptional stiffness and minimal distortion, even at high excursion levels. Its substantial displacement volume (Vd) of 2814.9 cm³ ensures powerful air movement, while the mechanical compliance (Cms) of 0.169 mm/N and low mechanical losses (Rms) of 6.25 kg/s contribute to precise, well-damped behaviour. The unit features an 8-hole mounting pattern with a cut-out diameter of 353 mm and a screw circle of 371 mm, making installation straightforward in most enclosures. With a depth of just 154 mm and a nominal diameter of 381 mm, the SS15-PR is a robust yet manageable addition to your audio setup.

Part of the acclaimed Dayton Audio Signature Series, this passive radiator combines advanced engineering with reliable build quality. Whether you are seeking to extend sub-bass output or refine transient response, the SS15-PR offers a versatile solution for audiophiles and DIY enthusiasts alike. Experience the difference a high-excursion passive radiator can make in your system.
