RCF MQ 80P Passive Speaker.The RCF MQ80P 2-way horn-loaded sound projector speaker system is the best option for getting clear voice and music reproduction in a mid-size space because of its high intelligibility, high efficiency, and compact design. Appropriate for background and foreground music systems and PA systems. The ability to combine it in clusters of two or more units and achieve wide, even coverage while reducing the installation locations is made possible by its 90° x 60° constant directivity and easy-to-use accessories. It is ideal for installations both inside and outside (IP 55). The woofer is a tuned enclosure with a high excursion, PP coated paper cone and rubber surround (port can be sealed for full outdoor installation).
