Frequently Asked Questions - X 28 L RCF
How do I connect the RCF X 28 L loudspeaker to an amplifier?
Connect the amplifier output to either one of the Speakon connectors on the rear of the loudspeaker. The X 28 L is a passive loudspeaker, so it requires an external amplifier with a suitable wattage rating. Ensure the amplifier is switched off before making or breaking connections to prevent damage.
What is the power handling of the X 28 L?
The RCF X 28 L handles 200 W RMS (root mean square) and 400 W peak power. We recommend using an amplifier capable of delivering between 200 W and 400 W into an 8 ohm load for optimal performance.
Can I use the X 28 L as a stage monitor?
Yes, the X 28 L's compact cabinet and angled back allow it to be used as a floor monitor. Position it at an appropriate angle and ensure it is placed on a stable surface to avoid movement during performance.
What is the recommended amplifier power for the X 28 L?
For best results, use an amplifier that provides 200 W to 400 W RMS per channel at 8 ohms. Avoid underpowering, as clipping from an underpowered amplifier can damage the compression driver.
How do I mount the X 28 L on a speaker stand?
The X 28 L has a 35 mm pole socket on the bottom, which fits standard speaker stands. Place the stand on a solid, level surface, secure the pole, and then position the loudspeaker onto the pole. For additional security, use a tilt brace if available.
How should I clean and maintain the X 28 L?
Clean the cabinet with a soft, dry cloth. Do not use water, solvents, or abrasive cleaners. Periodically inspect the grille and drivers for dust or debris. Loose dust can be removed with a vacuum cleaner set to low suction.
Does the X 28 L require an external crossover or DSP?
The loudspeaker contains an internal passive crossover, so it operates from a single amplified signal. It does not require an external DSP for basic operation, but using a DSP or controller can optimize equalization and protection when integrated into a professional system.
What are the key specifications of the RCF X 28 L?
Key specs include a frequency response of 70 Hz to 20 kHz, sensitivity of 95 dB, maximum SPL of 121 dB, and a 8 ohm impedance. It features a 8-inch woofer and a 1-inch compression driver in a bass-reflex enclosure.
Can the X 28 L be permanently installed?
Yes, the X 28 L can be used for installation applications. It has multiple M6 mounting points for attaching brackets. Ensure that the mounting structure can support the weight of the loudspeaker (11 kg) and that all hardware is rated for the load.
What safety precautions should I take when flying or angling the loudspeaker?
Always use rated mounting hardware and follow safety guidelines for rigging. Verify the integrity of the suspension points and do not exceed the recommended load capacity. Install safety backup wires where applicable and never suspend heavy loads overhead without proper certification.
