SB Acoustics SB23CACS45-8 8" Ceramic Woofer

The SB23CACS45-8 8" Ceramic Woofer from SB Acoustics represents a significant step forward in driver engineering, offering exceptional clarity and control for demanding audio applications. This 8-inch driver is ideally suited for use as a dedicated bass or mid-bass unit in high-fidelity loudspeaker systems, and it excels in both two-way and three-way designs where accurate, low-distortion reproduction is paramount. Its performance characteristics also make it an excellent choice for sealed or ported subwoofer enclosures, delivering tight, articulate low frequencies that integrate seamlessly with satellite speakers.

At the heart of this woofer lies a rigid ceramic cone, renowned for its high stiffness-to-mass ratio, which effectively suppresses cone breakup and ensures pistonic behaviour across its operating range. The advanced motor system, featuring a 45.47mm voice coil, provides exceptional power handling and linearity, while the low 0.6mH voice coil inductance contributes to extended high-frequency response and reduced distortion. With a total Q factor (Qts) of 0.4 and a resonant frequency (Fs) of just 25Hz, this driver offers excellent low-frequency extension and is well-suited to a variety of enclosure alignments. The 8-ohm impedance and 87.5dB sensitivity ensure compatibility with a wide range of amplifiers, making the SB23CACS45-8 a versatile and high-performance foundation for any serious loudspeaker project.
