PRV Audio 8MB450-4 v2 Bass-midwoofer

The PRV Audio 8MB450-4 v2 is a high-performance bass-midrange driver engineered to deliver powerful, articulate low-end response across a variety of audio applications. Whether you are upgrading your car audio system, constructing a dedicated home hi-fi loudspeaker, or designing a compact subwoofer enclosure, this 8-inch driver provides the perfect balance of efficiency and control. Its robust construction ensures reliable operation even under demanding conditions, making it an excellent choice for both DIY enthusiasts and professional installers seeking clean, natural sound reproduction.

At the heart of this driver lies a paper cone, chosen for its lightweight yet rigid properties, which contributes to a warm, uncoloured tonal character. The voice coil is wound with copper-clad aluminium wire (CCAW), reducing moving mass while maintaining excellent thermal conductivity for sustained high-power handling. With a sensitivity of 93.5 dB (1m/2.83V) and a total Q factor of 0.88, the 8MB450-4 v2 is well-suited for both sealed and ported enclosures, offering a maximum linear excursion of 4.5 mm for controlled bass output. The low voice coil inductance of 0.17 mH ensures extended high-frequency response, while the 3.6 ohm DC resistance provides compatibility with modern amplifier loads. Designed for a 182 mm cut-out and secured with four mounting holes, this driver combines technical precision with versatile installation options, delivering exceptional value for serious audio projects.
