Frequently Asked Questions - CMR 60T RCF

How do I connect the CMR 60T to a constant voltage line?

Remove the magnetic front grille and set the rotary switch to one of positions 1-5 for 70V or 1-4 for 100V. Use the Euroblock connector: connect the line positive to INPUT + and negative to INPUT -. If linking multiple speakers, use LINK terminals.

What is the correct power selection for 100V lines?

For 100V lines, use positions 1-4: 10W, 20W, 40W, or 80W. Do not select position 5 (N.C.) or position 6 (8Ω), as this may damage the speaker or amplifier.

Can I use the CMR 60T as a low-impedance speaker?

Yes. Set the rotary switch to position 6 (8Ω). The total impedance of all connected speakers must not be lower than the amplifier's output impedance. Wiring in parallel reduces total impedance.

What is the cut-out diameter for ceiling installation?

Drill a circular hole of 260 mm (10.24 inches) in the false ceiling. Insert the speaker and tighten the three screws to secure the locking clamps.

How do I remove the front grille?

The grille is held by magnets. Gently pull it away from the speaker. It has a safety cord that must be hooked into the tweeter horn slot before installation to prevent falling.

What amplifier power is recommended for the CMR 60T?

RCF recommends an amplifier with 160 W RMS power to handle the speaker's 80 W RMS and 320 W peak capability.

Is the CMR 60T suitable for outdoor use?

The speaker is designed for indoor use only. If used outdoors, ensure it is protected from rain and moisture. The product is not weatherproof.

How should I clean the speaker?

Use a dry cloth to clean the exterior surfaces. Do not use solvents, alcohol, or abrasives. Always clean with the power turned off.

What is the maximum number of CMR 60T speakers I can connect to a 100V line?

The total power of all speakers must not exceed the amplifier's power rating. For example, if the amplifier delivers 200W, you can connect up to two speakers at 80W each (160W total) or more at lower power taps.

Does the CMR 60T come with mounting hardware?

The speaker includes three locking plastic clamps for ceiling installation. Safety cord is included for the grille. Anchoring screws and eyebolts for safety cord attachment are not supplied; you must use appropriate hardware for your ceiling.

2. DESCRIPTION

CMR 50T W and CMR 60T W are multi-purpose two-way ceiling monitor speakers, suitable for a wide range of applications.

Thanks to their elegant and discreet design and refined finishes, these are suitable for all environmental and architectural conditions.

The two models differ in the size of their woofer and their power. They are both equipped with a transformer for connection to constant voltage lines (70-100 V):

• CMR 50T W 5" woofer, 40 W
• CMR 60T W 6.5" woofer, 80 W

The high quality of their transducers (arranged in a coaxial configuration) guarantees faithful and precise musical reproduction throughout the audio spectrum and allows to reach truly remarkable sound pressure levels for such compact products.

The connection is simple and safe thanks to the removable four-pole screw terminals.

The front grille is fixed by magnets and can therefore be easily removed to access the power rotary switch (their line transformer allows selection among five power rates).

MAIN FEATURES

• 5" woofer (CMR 50T W) with 1" voice coil
• 6.5" woofer (CMR 60T W) with 1.2" voice coil
• Neodymium 1" dome tweeter with 1" voice coil
• Self extinguishing plastic body and metal backcan
• Internal transformer for connection to constant voltage lines (70-100 V), power selection is made with a rotary switch among 5 rates. The low impedance connection (8 Ω) is possible too.
• EUROBLOCK removable 4-pole connector (audio input and parallel output 'link')
• Steel front grille with magnetic fixing
• Colour: white.

3. CONNECTION AND POWER SELECTION

WARNING! Speaker connections should be only made by qualified and experienced personnel having the technical how or sufficient specific instructions to ensure that connections are made correctly and prevent any electrical danger.

To prevent any risk of electric shock, do not connect speakers when the amplifier is switched on. Before turning the system on, check all connections and make sure there are no accidental short circuits.

The entire sound system shall be designed and installed in compliance with the current local laws and regulations regarding electrical systems.

Make sure all speakers are connected in phase to ensure a correct sound reproduction.

CMR 50T W and CMR 60T W can be either connected to 70 V / 100 V constant voltage lines or used as low impedance speakers (8 Ω).

Remove the front grille (fixed with magnets and with a safety cord) to access the power rotary switch (6 different settings).

3. CONNECTION AND POWER SELECTION

SETTING THE POWER WHEN CONNECTED TO 100 / 70 V CONSTANT VOLTAGE LINES

If speakers are connected to a constant voltage line, set the selector to one of the positions from 1 to 5 (70 V) or from 1 to 4 (100 V) to choose the power rate (according to the line voltage).

CMR 50T W

POSITION 1 2 3 4 5 6
70 V 2,5 W 5 W 10 W 20 W 40 W					8 Ω
100 V 5 W 10 W 20 W 40 W N.C.

CMR 60T W

POSITION 1 2 3 4 5 6
70 V 5 W 10 W 20 W 40 W 80 W					8 Ω
100 V 10 W 20 W 40 W 80 W N.C.

WARNING!

• DO NOT select position 6 (8 Ω) (as this may damage the speaker and the amplifier)!
• DO NOT select position 5 when linked to a 100 V line!
• The speaker input voltage (Vd) shall correspond to the amplifier output voltage (Va).
• The sum of nominal power values (Pd x n) of all speakers connected to the line shall not exceed the amplifier power (Pa).

3. CONNECTION AND POWER SELECTION

LOW IMPEDANCE CONNECTION (8 Ω)

Set the selector to position 6 (8 Ω).

• The total speaker impedance must not be lower than the amplifier output impedance.
• A speaker total impedance equal to the amplifier output one permits to get the maximum deliverable power (but a higher impedance entails less power).
• The total speaker power shall be adequate for the amplifier maximum deliverable power.
• Speaker lines shall be as short as possible (for long distances, it may be necessary to use cables with large cross-section wires).
• The impedance of a single speaker is 8 Ω. For example, the total impedance of the parallel of two speakers is 4 Ω (impedance = 8 / speaker number).

CONNECTION

Remove the metal protective cover of the speaker backcan to access to the removable Euroblock connector socket.

Technical diagram showing a circular mechanical component before and after assembly, with no visible text or symbols.

The two INPUT contacts (+ and -) allow the connection of the input cable, the two LINK contacts (+ and -) can be linked to an output cable for the parallel connection of other speakers.

Applicable wire section: from 0.75 mm ^2 to 2.5 mm ^2 .

1. Connect the line positive wire to the speaker INPUT +.
2. Connect the line negative wire to the speaker INPUT -.
3. If necessary, connect in the same way the output cable (to link other speakers in parallel) to speaker LINK + and LINK -.
4. Refit the metal protective cover on the speaker backcan.

WARNING! Remeber to fix a safety cord (not included) to a separate solid surface like a beam or a wall and tie it to the speaker through the safety loops or to the provided eyebolt (or both, if necessary, for added safety); the eyebolt must be securely screwed to one of the three anchoring points (1, 2, 3). The cord must be suitable for the speaker dimension and weight and, in case of dropping, it must be able to firmly hold the speaker and avoid any possible injury.

• The loudspeaker input voltage (Vd) shall correspond to the amplifier output voltage (Va).
• The sum of nominal power values (Pd x n) of all loudspeakers connected to the line shall not exceed the amplifier power (Pa).
• Make sure all loudspeakers are connected in phase to ensure a correct sound reproduction.

• Always use cables having wires with an adequate cross-section, considering the cable length and the total loudspeaker power.
• oudspeaker lines must be kept separated from mains cable, microphone cables or others, in order to avoid inductive phenomena may cause hum or noises.
• Use loudspeaker cables having twisted wires to reduce hum caused by inductive effects due to coupling with electromagnetic fields.

5. INSTALLATION

WARNING! Make sure all speakers are installed in a stable and secure way in order to avoid any conditions that may be anxious for persons or structures. Check that the false ceiling has the necessary mechanical characteristics to support the other weight without any risk of falling.

1. Drill a circular hole having a diameter ∅ 260 mm (10.24") in the false ceiling at the point chosen for the speaker installation.

1. Connect the speaker as previously described in the 'Connection' manual section.
2. Insert the speaker completely into the false ceiling hole.
