The SB Acoustics SB16FRPC25-7 Bass-midwoofer is a meticulously engineered 6.5-inch driver that delivers accurate, natural bass reproduction in compact enclosures. Designed for discerning audio enthusiasts, this broadband subwoofer excels in high-fidelity two-way systems or dedicated subwoofer applications, bringing depth and clarity to any listening environment. Whether you are building a custom bookshelf speaker, a refined home cinema setup, or a high-performance car audio system, this driver provides the foundation for a truly immersive soundstage.

At the heart of the SB16FRPC25-7 lies a paper cone paired with a low-loss suspension, ensuring a natural, uncoloured response across the frequency range. With a sensitivity of 91 dB (SPL at 1m/2.83V) and a total Q factor of 0.46, it offers an excellent balance between efficiency and controlled bass extension. The 6.1 mm linear excursion (Xmax) allows for dynamic output, while the low voice coil inductance of 0.22 mH and DC resistance of 5.2 ohms contribute to precise transient behaviour. The driver’s mechanical Q of 9 and electromagnetic Q of 0.48 further refine its performance, making it ideal for sealed or ported enclosures.

This robust unit features a nominal diameter of 152.4 mm, a cut-out diameter of 144.5 mm, and a mounting depth of 84.3 mm, fitting neatly into space-conscious designs. With four fixing holes on a 165 mm bolt circle, installation is straightforward. The SB Acoustics SB16FRPC25-7 is a versatile, high-quality choice for those seeking accurate, low-distortion bass in a compact form factor.
