The SB34SWPL76-4 Subwoofer from SB Acoustics is a premium 12-inch driver engineered to deliver deep, controlled bass with exceptional clarity. Designed for audiophiles and custom installers, this subwoofer excels in sealed and ported enclosures, making it ideal for high-end home theatre systems, stereo setups, and dedicated subwoofer builds where accurate low-frequency reproduction is paramount. Its robust construction ensures reliable performance in both music and film applications.

Technically, the SB34SWPL76-4 features a paper cone for natural, uncoloured sound and a ferrite magnet motor for high efficiency. With a total Q factor (Qts) of 0.33, it offers optimal damping for tight, articulate bass. The 3.5-ohm DC resistance and 5.3 mH voice coil inductance support stable amplifier loading, while the mechanical (Qms: 8.6) and electrical (Qes: 0.34) Q values indicate excellent control. The 304.8 mm nominal diameter requires a 305.2 mm cutout, with eight mounting holes for secure installation. A copper voice coil wire ensures thermal stability, and the sensitivity of 85 dB (1m/2.83V) balances output with precision.

This subwoofer is the perfect choice for those seeking authoritative low-end extension without sacrificing musicality. Its engineering excellence guarantees years of immersive listening.
