Accuton C173-6-191 Bass-midwoofer

The Accuton C173-6-191 7-inch Bass-midwoofer represents a pinnacle of engineering for discerning audio enthusiasts who demand uncompromising performance from their loudspeaker systems. This driver is meticulously crafted to deliver articulate, controlled bass and midrange reproduction, making it an ideal choice for high-end two-way designs, three-way systems, or as a dedicated midbass unit in multi-driver configurations. Whether you are building a reference-quality home audio setup or upgrading an existing loudspeaker, this driver excels in applications where precision and clarity are paramount.

At the heart of the C173-6-191 lies a rigid ceramic membrane, renowned for its exceptional stiffness-to-weight ratio, which effectively eliminates cone breakup and ensures pistonic motion across its operating range. With a resonance frequency of just 38.6 Hz and a maximum linear excursion of 5 mm, it produces deep, tight bass with minimal distortion. The driver’s electrical parameters reveal a total Q factor of 0.34, indicating excellent transient response and suitability for sealed or vented enclosures. A 38 mm voice coil and 0.72 mH inductance contribute to high power handling and controlled high-frequency roll-off. The 6-ohm impedance and 88 dB sensitivity ensure compatibility with a wide range of amplifiers, while the 146 mm cutout diameter simplifies installation. Combining advanced materials with precise engineering, this Accuton driver delivers a truly refined listening experience.
