Dayton Audio DS175-PR 6-1/2" Passive Radiator

The Dayton Audio DS175-PR 6-1/2" Passive Radiator is a high-quality passive radiator from the renowned Designer series, engineered to enhance low-frequency performance in audio systems. By replacing a traditional port in a sealed enclosure, this component allows for deeper, more controlled bass extension without the turbulence and chuffing often associated with ported designs. It is an ideal solution for custom speaker builds, home theatre subwoofers, and high-fidelity stereo setups where space is limited but bass quality is paramount.

Technically, the DS175-PR boasts a resonance frequency of just 24.5 Hz, enabling impressive low-end reach. Its maximum linear excursion (Xmax) of 8 mm and a displacement volume (Vd) of 103 cm³ ensure substantial air movement for robust bass output. The mechanical Q (Qms) of 5.57 and suspension compliance (Cms) of 1.15 mm/N contribute to precise, controlled cone behaviour. With a nominal diameter of 165.1 mm, a cut-out diameter of 143 mm, and a mounting depth of 47.8 mm, this passive radiator integrates seamlessly into compact enclosures. The cone area (Sd) of 128.7 cm² and equivalent volume (Vas) of 27.1 litres further define its performance parameters. Whether used to augment a small subwoofer or refine a two-way speaker design, the DS175-PR delivers clean, articulate bass that elevates any listening experience.
