About: PRV Audio 4MR60-4 Midrange Loudspeaker - 4 Ohms

The 4MR60-4 full range speaker delivers broad frequency coverage and flat midrange response that ensures vocals and instruments to deliver ideal sound. The 4″ midrange speaker 4MR60-4 is a pro audio midrange with very high sensitivity and a smooth extended frequency response up to 8 kHz. The small dimensions and high output make it very useful to use in compact line array systems as a transition between the mid bass and high frequency way.

Each material and component such as the woven fiber glass cone, large spider, and rubber surround is carefully chosen to ensure a great sound quality and low distortion. The 4MR60-4 even operates at high power. It is also applicable in home theaters, satellites, and surround speakers as well as in car audio when you are limited in space and require extended frequency response. Each material and component such as the woven fiber glass cone, large spider, and rubber surround is carefully chosen to ensure a great sound quality and low distortion, it even operates at high power.
