About: PRV Audio 8MR600X 8" 300W RMS Midrange Speaker - 8 Ohm (Each)

X-treme mid range performance is what PRV Audio’s 8MR600X is all about. Made to be a class leading mid range in the pro audio realm, this driver has a sensitivity of 98 dB and only weighs 7 pounds. This low frequency driver is optimized for professional audio or MI (musical instrument) speaker system applications, a car audio version is available at 4ohms 8MR600X-4. 

The powerful magnet assembly assures high flux concentration. The ventilated basket designed between the basket and the magnetic structure significantly improves thermal connection and heat dissipation, further increasing power handling and lowering power compression. Capable of high output and low distortion, this mid range is perfect for filling in the important mid range response in any high output sound system.

The 51 mm (2 in) copper clad aluminum wire is wound in a double layer using a high temperature resin adhesive on a strong polyimide former and features a generous 14.5 mm winding length for extended Xmax and less distortion. The 2″ voice coil also ensures high heat dissipation and the necessary motor strength to deliver high sensitivity even on high power with the minimum distortion.

A Qts of 0.37 and an unique double roll dimple suspension design allows for a flat response from 200Hz to 2500Hz, even at high excursion controlling well its natural paper cone at its 5.25 mm Xmax. Its composite cone is built with non-pressed paper (visible on the back side) for reduced break-up and smooth sound.
