The NX L24-A Active Two-Way Column Speaker Array from RCF is a 1400W active column speaker array system. It is composed of four 6" woofers, and a 2.5" voice coil compression driver, which is loaded from a waveguide on a 100° x 30° constant directivity horn. It is designed to allow coherent sound dispersion while minimizing lobing in a compact enclosure.

The wide coverage horizontal angle and the controlled vertical dispersion allow for correct sound reproduction serving a wide area and assistance in limiting feedback and reverberated sound. The integrated DSP manages crossover, equalization, soft limiter, compressor and dynamic bass boost protections. Equalizations are available to operate with a single column or in pairs.

The ND 640 compression driver is loaded from a waveguide to a constant directivity 100° x 30° horn. The ND 640's 2.5" voice coil allows a crossover point of 800Hz, which allows a wide vocal range to be produced by this driver. The NXL 24-A is powered by a 1400W peak power digital amplifier, split 400W for the HF and 1000W for the LF. The DSP handles the processing within the cabinet and allows adjustment for a single column application or HF close coupling application.

The NXL 24-A presents a SMPS power supply section in order to produce maximum output and reduce transportation weight. A Mic/Line switch to adjust the input sensitivity is provided. When used just for speech, the Mic setting allows to use a microphone directly with the speaker. Set the selector to Line when using the speaker for live music or playback. A back-panel volume knob allows to set the overall volume of the speaker according to its application. This unit provides Power, Signal, and Status LEDs for monitoring the system.

Using its accessory is possible to fly 2 NXL 24-A units in HF close coupling configuration with a choice of three possible angles (0°, 15°. 20°). It is also possible to pole mount the system and due to a second pole mount on top of the cabinet, it is possible to couple two units. The cabinet is equipped with four rubber protections and two aluminum side handles for rental use and easy transportation. NXL 24-A cabinet is enclosed in Baltic Birch Plywood with internal structural metal bracings

Low Frequencies

1.5" Inside-Outside voice coil
Water resistant fiber doped cone
Polycotton M-roll surround
High power magnetic structure

Edge Wound Voice Coils

To ensure increased linear frequency response and maximum SPL output

High Frequencies

ND 640 large format compression driver, with a 2.5" voice coil allows a crossover point of 800Hz, and a large vocal range production

Inside/Outside Voice Coils

The dissipation surface is doubled - the adhesion area to the former is doubled - during thermal expansion the former is squeezed between inside and outside layers offering mechanical resistance.

Specific designed waveguide

ND 640 compression driver loaded from a waveguide to a constant directivity 100° x 30° horn.


DSP controlled Input section with single or dual equalizer preset


Pole mountable, stackable, and flyable
