SB Acoustics SW26DBAC-00 10'' Passive Radiator

The SW26DBAC-00 10'' Passive Radiator from SB Acoustics is a high-quality solution for enhancing low-frequency output in speaker designs without the need for a ported enclosure. This passive radiator is engineered to deliver deep, controlled bass extension, making it an ideal choice for audiophiles and DIY speaker builders seeking to optimise performance in compact cabinets.

This component excels in applications where traditional bass reflex ports are impractical due to space constraints or tuning difficulties. It is particularly well-suited for use in subwoofer systems, high-end bookshelf speakers, and custom audio projects where maximising low-end response while minimising distortion is critical. By replacing a port, it eliminates chuffing noise and allows for more flexible cabinet design.

Technically, the SW26DBAC-00 features a resonance frequency of just 13 Hz, enabling exceptional low-frequency extension. With a maximum linear excursion of 17 mm, it can handle significant air movement for powerful bass output. The mechanical Q (Qms) of 8.8 and a suspension compliance (Cms) of 0.39 mm/N ensure precise control, while the equivalent volume (Vas) of 53.8 litres aids in straightforward system integration. Its 254 mm nominal diameter fits standard 10-inch cutouts.

In summary, this passive radiator offers a robust and refined way to augment bass performance, combining SB Acoustics' engineering excellence with practical design flexibility for serious audio enthusiasts.
