SEAS Prestige SP26R - H9946 Passive Radiator

The SEAS Prestige SP26R - H9946 10" Passive Radiator represents a refined solution for audiophiles seeking to augment low-frequency performance without the complexity of a ported enclosure. As part of the esteemed SEAS Prestige series, this passive radiator is engineered to deliver deep, articulate bass extension, making it an ideal upgrade for high-fidelity loudspeaker systems. Its primary application lies in compact or sealed cabinet designs where traditional ports are impractical, allowing you to achieve a more natural, room-friendly bass response with reduced distortion.

Technically, the SP26R boasts a resonance frequency of just 22 Hz, enabling it to reproduce subterranean frequencies with authority. The maximum linear excursion (Xmax) of 28 mm ensures controlled, high-output performance even at demanding listening levels. With an equivalent volume (Vas) of 214 litres and a mechanical compliance (Cms) of 1.25 mm/N, this radiator pairs seamlessly with a wide range of woofers. The nominal diameter of 254 mm (10 inches) and a cone area (Sd) of 35 cm² provide ample displacement for impactful bass. Designed for a mounting hole diameter of 5 inches, it integrates straightforwardly into custom builds. Whether you are refining a two-way monitor or a multi-driver floorstander, the Prestige SP26R offers a premium, low-distortion path to deeper, more immersive low-end reproduction.
