Accuton C168-6-990 Cell Mid-range

The Accuton C168-6-990 6.5-inch Cell Mid-range driver represents a pinnacle of engineering for discerning audio enthusiasts who demand uncompromising clarity and precision. Designed as a dedicated mid-band subwoofer, this driver excels in high-end audio systems where accurate mid-range reproduction is paramount. Its exceptional build quality and advanced materials make it an ideal choice for both custom loudspeaker designs and upgrading existing reference systems, delivering a level of detail that brings recordings to life.

This driver is perfectly suited for use in multi-way loudspeaker configurations, particularly in three-way or four-way systems where it handles the critical mid-range frequencies. With a low total Q factor (Qts) of 0.21, it offers superb transient response and controlled bass alignment, ensuring tight, articulate performance. The high sensitivity of 93 dB (SPL at 1m/2.83V) means it pairs efficiently with a wide range of amplifiers, while the low voice coil inductance of 0.06 mH minimises distortion at higher frequencies.

Technically, the C168-6-990 features a resonant frequency (Fs) of 55 Hz and an equivalent volume (Vas) of 10.3 litres, with a moving mass (Mms) of 16.1 grams. The mechanical compliance (Cms) of 0.52 mm/N and a BL product of 11.7 T·m ensure precise motor control. With a maximum linear excursion (Xmax) of 3 mm and a cone area (Sd) of 118 cm², this driver delivers authoritative mid-range presence. The DC resistance (Re) is 5.4 ohms, and the mechanical (Qms) and electrical (Qes) Q factors are 4.76 and 0.22 respectively, confirming its refined engineering for audiophile-grade sound.
