The SB15NAC30-8 5-inch Mid-Woofer from SB Acoustics represents a refined blend of engineering and material quality, designed to deliver accurate mid-bass reproduction in high-fidelity audio systems. This driver is ideally suited for use in two-way or three-way loudspeaker designs, where it excels at handling the critical midrange and upper bass frequencies with clarity and control. It is also an excellent choice for compact subwoofer applications or as a dedicated mid-bass unit in multi-driver arrays, making it a versatile component for both DIY enthusiasts and professional loudspeaker builders.

Technically, this driver features a low 0.14 mH voice coil inductance, which minimises distortion and ensures consistent performance across the frequency range. With a total Q factor (Qts) of 0.37 and a resonance frequency (Fs) of 35.5 Hz, it offers a well-damped response suitable for sealed or ported enclosures. The 30.48 mm voice coil and 5 mm linear excursion (Xmax) provide robust power handling and dynamic capability, while the 85.5 dB sensitivity ensures efficient use of amplifier power. The NAC Aluminum series construction combines a rigid aluminium cone with a low-loss suspension, delivering precise transient response and reduced colouration. Whether for a high-end home audio project or a professional monitoring system, this mid-woofer offers exceptional performance and reliability.
