Accuton AS250-6-552 Cell Mid-range

The Accuton AS250-6-552 Cell Mid-range driver represents a pinnacle of engineering for discerning audio enthusiasts who demand uncompromising clarity and control. Designed as a dedicated mid-range transducer, this 228.6 mm (9-inch) driver excels in high-fidelity loudspeaker systems, where it delivers precise midrange reproduction with a remarkably controlled bass extension. Its performance makes it an ideal choice for both two-way and three-way designs, as well as for use in studio monitors and high-end home audio installations where accuracy is paramount.

Technically, the AS250-6-552 is built around a copper voice coil with a DC resistance of 7.3 ohms and an inductance of 0.67 mH, ensuring excellent transient response and thermal stability. The driver’s low total Q factor (Qts) of 0.38, combined with a mechanical Q (Qms) of 5 and an electrical Q (Qes) of 0.4, indicates a well-damped, tightly controlled behaviour ideal for sealed or vented enclosures. With a maximum linear excursion (Xmax) of 9 mm and a mechanical loss factor (Rms) of 2.52, it offers substantial cone movement while maintaining low distortion. The six mounting holes and a cut-out diameter of 23 mm facilitate straightforward installation, while the overall dimensions of 25 mm depth ensure compatibility with a wide range of cabinet designs. This driver is a testament to Accuton’s commitment to sonic excellence.
