Accuton AS190-9-251 Cell Mid-range

The Accuton AS190-9-251 Cell Mid-range driver represents a pinnacle of engineering for discerning audio enthusiasts who demand uncompromising sound quality. This 203 mm (8-inch) transducer is designed to deliver exceptionally precise midrange reproduction with remarkably low distortion, thanks to its advanced cell structure cone technology. Whether employed in a high-end two-way loudspeaker system or as a dedicated midrange in a multi-way design, this driver excels at rendering vocals and instruments with stunning clarity and realism. Its controlled bass response also makes it suitable for use in compact subwoofer configurations where accuracy is paramount.

Technically, the AS190-9-251 features a 12-ohm impedance and a sensitivity of 84 dB SPL (1m/2.83V), ensuring compatibility with a wide range of amplification. The driver boasts a linear excursion (Xmax) of 9 mm, supported by a robust motor system with a total Q factor (Qts) of 0.44, balancing tight, controlled low-frequency output with excellent transient response. The voice coil inductance (Le) is a low 1.05 mH, contributing to extended high-frequency performance. With a mounting depth of 137 mm and a cut-out diameter of 170 mm, this driver is designed for straightforward integration into custom enclosures. The combination of a mechanical Q (Qms) of 4.75 and an electromagnetic Q (Qes) of 0.49 ensures optimal damping and power handling. For the audiophile seeking the highest level of midrange purity and dynamic capability, the Accuton AS190-9-251 is an exceptional choice that will elevate any serious loudspeaker project.
