SB Acoustics Satori WO24P-4 9.5" Egyptian Papyrus Cone Woofer

The Satori WO24P-4 9.5" Egyptian Papyrus Cone Woofer from SB Acoustics represents a pinnacle of subwoofer engineering, designed to deliver deep, controlled bass with exceptional clarity. This driver is ideal for audiophiles seeking to elevate their high-fidelity systems, whether in a dedicated stereo setup, a home theatre environment, or a custom loudspeaker project. Its unique cone material and advanced motor structure make it particularly suited for sealed or ported enclosures where accurate, low-distortion reproduction of the lowest frequencies is paramount.

Technically, this woofer boasts a sensitivity of 91 dB (1m/2.83V) and a total Q factor (Qts) of 0.4, ensuring a balanced blend of transient response and extension. The resonance frequency (Fs) is a low 28 Hz, while the maximum linear excursion (Xmax) reaches 8.5 mm, allowing for substantial air movement without distortion. The 49.28 mm voice coil and 3.3 ohm DC resistance (Re) are optimised for the 4 ohm impedance, and the low voice coil inductance (Le) of 0.29 mH contributes to excellent high-frequency behaviour. With a mechanical Q (Qms) of 6.7 and an electromagnetic Q (Qes) of 0.42, this driver offers precise control and a natural, musical character. The exclusive Egyptian papyrus cone, combined with a robust suspension (Cms: 0.77 mm/N) and a 255 cm² cone area (Sd), delivers a rich, articulate bass response that will satisfy the most discerning listener.
