PRV Audio 4MR60-4 Mid-range Woofer

The PRV Audio 4MR60-4 Center Subwoofer is a compact yet powerful bass and mid-bass driver designed to deliver tight, controlled low-frequency performance in space-constrained installations. Engineered for audiophiles and custom installers alike, this 4-inch subwoofer excels in centre-channel speaker systems, small sealed enclosures, or as a dedicated mid-bass driver in multi-way setups where accurate response and minimal footprint are paramount. Its versatility makes it ideal for home theatre, car audio, and professional sound reinforcement applications requiring precise bass reproduction without sacrificing clarity.

At the heart of the 4MR60-4 lies a robust glass-fibre cone, chosen for its stiffness and low mass, ensuring clean, distortion-free output across its operating range. The voice coil employs copper-clad aluminium wire (CCAW) for efficient heat dissipation and reduced moving mass, contributing to a total Q factor (Qts) of 0.68—a figure that balances transient response with extended low-end extension. With a sensitivity of 90 dB (1m/2.83V) and a maximum linear excursion (Xmax) of 2.87 mm, this subwoofer delivers impressive output for its size. The 3.6-ohm DC resistance and low voice coil inductance (Le: 0.2 mH) further enhance control and detail. Mechanically, the driver features a 102 mm cut-out diameter, four mounting holes, and a shallow 60 mm depth, simplifying integration into slim enclosures. Whether reinforcing a centre channel or adding punch to a compact system, the PRV Audio 4MR60-4 offers a refined solution for discerning listeners.
