The Dayton Audio CF120-4 4-1/2" Woven Carbon Fiber Midwoofer represents a significant step forward in driver technology, offering a remarkable blend of rigidity and lightweight construction. This 4-ohm unit is engineered to deliver exceptionally clear, detailed midrange frequencies alongside punchy, well-defined bass, making it an ideal choice for discerning audiophiles building high-performance car audio systems or compact home theatre setups. Its versatility also extends to custom multi-way speaker designs where accurate mid-bass reproduction is paramount.

At the heart of this driver lies a woven carbon fibre cone, renowned for its exceptional stiffness-to-mass ratio, which effectively suppresses unwanted cone breakup and resonance. This results in a remarkably clean and natural sound signature. The motor system is equally impressive, featuring a low total Q factor (Qts) of 0.28, which indicates excellent transient response and tight, controlled bass. With a sensitivity of 89.1 dB and a maximum linear excursion (Xmax) of 3.5 mm, this midwoofer can produce significant output with minimal distortion. The copper voice coil and a DC resistance of 3.4 ohms ensure efficient power handling, while the 57.2 mm mounting depth and 95.3 mm cutout diameter allow for straightforward installation in a variety of enclosures. For those seeking a premium driver that combines advanced materials with precise engineering, the CF120-4 is a superb choice.
