Product Description

PRV Audio 6MR250B-4 SLIM 6" Mid Range Bullet Slim Loudspeaker


  • The MR SLIM series was designed as PRO Audio On Wheels solution for shallow doors, featuring an Aluminum Phase Plug (Bullet). This mid is built like a professional mid range loudspeaker, but it has been designed for use in the mobile audio market, as we called it Pro Audio On Wheels®!
  • By combining elements from PRO Audio and Car Audio we have developed a NEW type of high efficient mid range that is able to give high levels of output from stock speaker location in your car.


  • Slim Design – Perfect for door stock location
  • Sound Quality without Cutting up interior Panels
  • Endurance at Loudest Volumes
  • Vented Air pole piece for heat dissipation
  • Center phase plug for even sound distribution
  • 4 Ohms Impedance
  • The “bullet” phase plug is made from pure aluminum acting as a radiator cooling system for the voice coil and machined to perfection for even sound dissipation. Beyond good looks, this cone is extremely light, providing excellent damping to keep an incredibly natural yet accurate sound.
  • Also featuring a cloth M-roll surround helping resonance to be kept under control making for an easy transition to a super tweeter.
  • The suspension design of this mid range features the single layer spider – which connects to the coil former with premium stitched lead wires, all being driven by a copper-clad aluminum wire voice coil providing high efficiency and excellent power handling.
  • You can expect outstanding sound stage quality and realistic sound reproduction for a great value.
  • Built for compact spaces and able to handle 250 watts of continuous power. Its slim design makes this the perfect car audio door speaker, allowing it to be utilized in endless ways.
  • Loud and clear vocals all within 2.14″ of mounting depth without sacrifice quality and performance.
