Monacor SPH-170C 7'' Carbon Fiber Midwoofer

The Monacor SPH-170C is a 7-inch carbon fibre midwoofer engineered to deliver a remarkable blend of tight, controlled bass and articulate midrange performance. With an 8-ohm impedance and a robust design, this driver is ideally suited for high-fidelity audio systems, including two-way or three-way speaker builds, as well as dedicated subwoofer applications in compact enclosures. Its rigid carbon fibre cone ensures minimal distortion and exceptional transient response, making it a superb choice for audiophiles seeking precision and clarity across the lower and mid frequencies.

Technically, the SPH-170C features a total Q factor of 0.26 and an electromagnetic Q of 0.27, indicating excellent damping and suitability for sealed or ported enclosures. The maximum linear excursion of 4 mm, combined with a sensitivity of 88 dB SPL at 1 metre with 2.83 V, allows for dynamic output with low distortion. The copper voice coil wire and 0.8 mH inductance contribute to efficient power handling and controlled behaviour. With a nominal diameter of 177.8 mm, a mounting cut-out of 145 mm, and a depth of 90 mm, this driver integrates seamlessly into custom designs. The six mounting holes ensure secure installation, while the carbon fibre membrane guarantees long-term reliability and sonic accuracy. Whether for a refined home audio project or a professional sound system, the Monacor SPH-170C delivers exceptional performance.
