SB Acoustics SB36WBAC21-8 Full-range Woofer

The SB36WBAC21-8 Full-range Woofer from SB Acoustics is a meticulously engineered broadband subwoofer designed to deliver deep, controlled bass and articulate midrange performance within compact enclosures. This driver is ideal for audiophiles and DIY enthusiasts seeking to build high-fidelity loudspeakers, satellite-subwoofer systems, or multi-channel home theatre setups where space is at a premium but sonic accuracy cannot be compromised. Its full-range capability also makes it suitable for use in soundbars and small bookshelf speakers, providing a cohesive soundstage without the need for additional crossover components.

Technically, the woofer features a rigid aluminium cone that ensures low distortion and excellent transient response, while the 3.5mm linear excursion (Xmax) allows for substantial air movement, producing deep, impactful low frequencies. The total Q factor (Qts) of 0.61 strikes a balance between sealed and ported alignments, offering design flexibility. With a sensitivity of 75 dB SPL at 1m/2.83V and an 8-ohm impedance, it integrates seamlessly with a wide range of amplifiers. The low voice coil inductance (Le) of 0.13 mH and DC resistance (Re) of 6.4 ohms contribute to clean, extended high-frequency reproduction. The driver’s compact 25.4 cm nominal diameter and 20.8 cm depth, combined with a 36 mm mounting hole, simplify integration into bespoke cabinets. Whether for a refined stereo pair or a dedicated subwoofer, this SB Acoustics driver offers exceptional build quality and acoustic performance.
