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.
