The Accuton AS250-8-552 Cell Mid-range driver represents a pinnacle of engineering for audiophiles and professional system designers seeking uncompromising bass performance. As a dedicated bass-mid-bass subwoofer from the renowned German manufacturer, this 11-inch (279.4mm) driver is crafted to deliver deep, controlled low-frequency response with exceptional clarity. Its robust construction and advanced motor system make it an ideal choice for high-end home audio, studio monitoring, or custom car audio installations where accurate transient reproduction and minimal distortion are paramount.

Technically, the AS250-8-552 boasts a low total Q factor (Qts) of 0.33, ensuring precise damping for tight, articulate bass. The combination of a low electrical Q (Qes: 0.35) and higher mechanical Q (Qms: 5) contributes to its controlled behaviour. With a maximum linear excursion (Xmax) of 9mm and a sensitivity of 87dB SPL (1m/2.83V), this driver can handle significant power while maintaining composure. The 8-ohm DC resistance (Re: 8Ω) and low voice coil inductance (Le: 0.5mH) facilitate easy integration with amplifiers. The driver requires a 227mm cut-out and has a mounting depth of 141mm, secured by six mounting holes. Whether used in a sealed or ported enclosure, the Accuton AS250-8-552 delivers the authoritative, refined bass that discerning listeners demand.
