MQ 50i 2 WAY IN WALL SPEAKER DESCRIPTION MQ 50i is a 2-way Bass Reflex acoustic speaker with 5” high-excursion woofer with rubber suspension and soft dome tweeter loaded on a wave guide to ensure clarity and proper sound dispersion over a wide range of coverage. Its sound accuracy, compact size and design make this ‘In wall’ speaker ideal for reproducing music and speech. It includes a transformer inside for the connection to (100 – 70 V) constant voltage lines, yet it can also be set to 16 Ω (low impedance connection). MQ 50i is available in white (MQ 50i-W) or silver (MQ 50i-S) colour

INSTALLATION NOTES Installation of the MQ 50i is quick thanks to be mounted on a flush-mounting box type “Multibox” (2 modules) by BTicino® (or equivalent). It comes complete with a back metal case with cable management for applying to walls in plasterboard or other types of panelling. The power can be easily selected by using the Rotary switch present on the front panel; the knob is accessible using fingers. Connections are made by a Euroblock connector. The enclosure is constructed of high density UV resistant self-extinguishing polystyrene with robust steel grill. RCF products are continually improved. All specifications are therefore subject to change without notice.
