The Accuton S220-11-221 Bass-midwoofer represents a pinnacle of engineering for discerning audio enthusiasts seeking uncompromising low-frequency performance. This 221mm driver is meticulously crafted to deliver deep, articulate bass that remains controlled and musical, making it an ideal foundation for high-end two-way or multi-way loudspeaker systems. Whether employed in a dedicated subwoofer configuration or as a bass-midrange unit in a reference-quality monitor, its exceptional transient response ensures every note is rendered with precision and authority.

Technically, the S220-11-221 boasts a remarkably low resonance frequency of 22.1 Hz, enabling genuine sub-bass extension without sacrificing speed. The total Q factor of 0.37 indicates a well-damped alignment, offering a seamless blend of low-frequency extension and tight, accurate reproduction. With an impedance of 11 ohms and a sensitivity of 88 dB (1m/2.83V), it integrates efficiently into both valve and solid-state designs. The 5 mm linear excursion (Xmax) provides ample headroom for dynamic peaks, while the 0.81 mH voice coil inductance ensures minimal distortion at higher frequencies. The driver’s 191 mm cut-out diameter and 105 mm depth facilitate straightforward installation into carefully braced enclosures. For those who demand the very best in bass reproduction, this Accuton driver delivers an unparalleled combination of depth, control, and sonic purity.
