The SB29NRX75-8 Norex Subwoofer from SB Acoustics is a high-performance 29 cm driver engineered to deliver deep, controlled bass with exceptional clarity. As part of the acclaimed NRX Norex series, this subwoofer is designed for audiophiles and custom installers seeking to elevate their home audio or car audio systems with precise low-frequency reproduction. Whether used in a sealed enclosure for tight, articulate bass or a ported design for extended low-end output, it excels in music and home theatre applications, adding weight and realism to any soundtrack.

Technically, the subwoofer features a robust cast aluminium frame that minimises resonance and ensures structural rigidity. The advanced Norex cone material provides optimal stiffness-to-mass ratio, reducing distortion even at high excursion levels. With an Xmax of 11 mm, a total Q factor of 0.37, and a sensitivity of 88 dB, it offers excellent linearity and efficiency. The 8-ohm impedance variant (Re 6.2 ohms) and 2.3 mH voice coil inductance facilitate easy integration with amplifiers. Measuring 133.1 mm in depth and requiring a 5.5-inch cutout, this subwoofer is a refined choice for achieving authoritative, musical bass.
