PRV Audio 3MR40-NDY-4 Mid-range Woofer

The PRV Audio 3MR40-NDY-4 Neodymium Midrange Woofer is a precision-engineered driver designed to deliver exceptional clarity and detail in the critical midrange frequencies. As part of PRV Audio's respected lineup, this compact yet powerful woofer excels in applications where space is at a premium but sonic performance cannot be compromised. Its neodymium magnet structure provides remarkable efficiency in a lightweight package, making it an ideal choice for custom car audio installations, home theatre systems, and professional sound reinforcement enclosures where accurate vocal and instrument reproduction is paramount.

Technically, this midrange woofer features a glass-fibre cone that offers excellent stiffness-to-weight ratio, ensuring controlled cone behaviour and low distortion even at higher output levels. The CCAW (Copper-Clad Aluminium Wire) voice coil contributes to reduced moving mass and improved transient response, while the low voice coil inductance of just 0.01 mH helps maintain consistent performance across the frequency range. With a total Q factor (Qts) of 0.77, a mechanical Q (Qms) of 3.41, and an electrical Q (Qes) of 0.99, this driver is well-suited for sealed and ported enclosures, offering a balanced blend of efficiency and damping. The 76.2mm nominal diameter and 1.4mm Xmax allow for respectable linear excursion, while the 93.7mm overall frame size and 71mm cut-out diameter ensure straightforward installation. With a sensitivity of 91 dB and a DC resistance of 3.4 ohms, this woofer delivers clear, articulate midrange that brings your audio to life.
