TWO-WAY CEILING MONITOR SPEAKER SYSTEM

Compact design, light weight and limited depth make the RCF MQ 50C-W (white) and

MQ 50C-S (silver) 2-way ceiling monitor loudspeakers ideal for use in any PA systems

and background/foreground music systems where the good sound is required.

The woofer is a high-excursion, PP coated paper cone – rubber surround design

mounted in a tuned enclosure. The fabric dome tweeter is loaded on a constant

Q wave guide to provide natural, smooth sound reproduction on a wide dispersion

angle.

Installation of the MQ 50C is fast and efﬁ cient using the built in rotating hooks. No

additional brackets or rings or other supports are required: thanks to its lightweight

construction the speaker can be mounted as a conventional ceiling speakers.

Connections are made to four polar loop thru Euroblock male and female to get

parallel IN/OUT connection.

Wattage taps and voltage adjustments together with 16-ohm operation are selecta-

ble by means of a Rotary switch, accessible under the frontal grill.

The enclosure is constructed of high density UV resistant self-extinguishing polysty-

rene and includes a protective perforated steel grille. Back dome is made of alumi-

nium. MQ 50C is available in white (MQ 50C-W) or silver (MQ 50C-S) colour. A front

protection is provided for over-painting bezel and grill.
