SB Acoustics SB15BAC30-8-COAX Coaxial Woofer

The SB Acoustics SB15BAC30-8-COAX Coaxial Subwoofer represents a sophisticated solution for those seeking to combine deep, authoritative bass with clear, full-range audio from a single driver. This innovative design is ideal for compact loudspeaker systems, automotive audio installations, or any application where space is at a premium yet uncompromising sound quality is demanded. By integrating both a woofer and a centrally mounted tweeter, it eliminates the need for separate drivers, simplifying enclosure design and crossover requirements while delivering a coherent, point-source soundstage.

Technically, this 15cm (nominal 127mm) coaxial driver features a copper-clad aluminium wire (CCAW) voice coil, ensuring low moving mass and excellent transient response. With a total Q factor (Qts) of 0.36 and a mechanical Q (Qms) of 4.8, it is well-suited for sealed or ported enclosures, offering controlled, tight bass. The maximum linear excursion (Xmax) of 6mm allows for substantial output without distortion, while the sensitivity of 86dB (SPL 1m/2.83V) ensures efficient power handling. The low voice coil inductance (Le) of 0.13mH contributes to extended high-frequency performance from the integrated tweeter. With a DC resistance (Re) of 3.8 ohms and a mounting cutout diameter of 121mm, this subwoofer is engineered for straightforward integration. Whether for a high-fidelity home theatre or a refined car audio system, the SB Acoustics SB15BAC30-8-COAX delivers exceptional performance in a compact, all-in-one package.
