Dayton Audio Signature SS8-PR Passive Radiator

The Dayton Audio SS8-PR Signature Series 8" Passive Speaker is a high-quality passive radiator engineered to elevate the performance of your subwoofer system. By replacing a traditional port, this unit allows for extended low-frequency response without the turbulence and noise associated with vented enclosures, delivering cleaner, more articulate bass. Ideal for custom audio projects, it seamlessly integrates with active drivers in sealed enclosures, making it a superb choice for home theatre setups, high-fidelity stereo systems, or professional sound installations where space is at a premium but deep, controlled bass is essential.

Technically, this passive radiator boasts a resonance frequency of 37.4 Hz and a displacement volume (Vd) of 496, ensuring robust low-end extension. Its aluminium basket and frame provide rigidity and reduced distortion, while the mechanical suspension compliance (Cms) of 0.212 and mechanical loss factor (Rms) of 7.84 contribute to precise cone control. With a nominal diameter of 203.2 mm, a mounting hole diameter of 5.5 inches, and a depth of 92 mm, it fits standard enclosures with ease. The eight mounting holes and 184 mm baffle cut-out diameter simplify installation, making the SS8-PR a reliable upgrade for any serious audio enthusiast seeking refined, powerful bass reproduction.
