The PRV Audio 5MR450-NDY Centre Subwoofer is a compact yet powerful driver designed to deliver tight, controlled bass with remarkable clarity. Engineered for audiophiles and custom installers alike, this 127mm paper-cone transducer excels in sealed centre-channel and subwoofer enclosures, where its precise low-frequency extension brings depth to home theatre systems, studio monitors, and high-fidelity audio setups. Its versatile performance also makes it an ideal choice for upgrading factory car audio systems or building bespoke compact subwoofer modules.

At the heart of this driver lies a 0.64 total Q factor (Qts), which ensures excellent low-end response in sealed boxes while maintaining musical accuracy. The paper cone material provides a natural, warm tonality, while the copper voice coil wire offers reliable thermal handling and low inductance (Le: 0.03 mH) for minimal distortion. With a sensitivity of 94 dB (1m/2.83V) and a maximum linear excursion (Xmax) of 3.45 mm, the 5MR450-NDY balances efficiency with controlled cone movement. The 6.9 ohm DC resistance (Re) and four mounting holes simplify integration, while the 75 mm depth and 147 mm overall dimensions allow for flexible placement. Whether for a dedicated centre channel or a compact subwoofer, this PRV Audio driver delivers authoritative, articulate bass.
