The SB17NRX2C35-8 Norex Bass-midwoofer from SB Acoustics is a meticulously engineered 6.5-inch driver designed to deliver accurate, controlled bass and midrange reproduction. This high-quality transducer is ideal for audiophile-grade two-way or three-way loudspeaker systems, as well as compact subwoofer applications where precise low-frequency extension is required. Its robust construction and advanced motor system make it a superb choice for both DIY enthusiasts and professional speaker builders seeking a reliable, high-performance foundation.

Technically, this driver features a cast aluminium frame that provides exceptional rigidity and significantly reduces unwanted resonances, ensuring cleaner sound across the frequency range. The motor system is optimised with a total Q factor (Qts) of 0.42, balancing transient response and bass extension for versatile enclosure designs. With a maximum linear excursion (Xmax) of 5.5 mm and a sensitivity of 87 dB SPL at 2.83V/1m, it offers impressive output capability. The low voice coil inductance (Le) of 0.15 mH contributes to extended high-frequency response, while the 5.7-ohm DC resistance (Re) ensures compatibility with typical amplifier loads. The 171 mm nominal diameter and 85.9 mm mounting depth allow for straightforward integration into most cabinets.

In summary, the SB17NRX2C35-8 Norex Bass-midwoofer combines advanced engineering with practical performance, making it a standout choice for achieving articulate, dynamic bass and clear midrange in high-fidelity speaker designs.
