RCF NXL 24-A MK2 Powered Two-Way Line Array Column Speaker

RCF NXL 24-A MK2 Active Line Array Column for Modern Live Sound

The RCF NXL 24-A MK2 is a powered line array column built to deliver big-system performance from a slim footprint. A 2100 W Class-D amplifier drives a 3-inch titanium neodymium compression driver and four 6-inch high power neodymium woofers, producing up to 132 dB SPL over a linear 60 Hz – 20000 Hz frequency range. With a constant directivity pattern of 100° x 30°, it is voiced for bands, DJs, clubs, and rental companies that need tight control and clean coverage from compact columns.

At the heart of the system is the NXL MK2 two-channel Class-D amplifier, rated 50% more powerful than previous generation modules. It manages extreme sound pressure levels with fast attack, realistic transient response, and low power loss. The amplifier is convection-cooled via a solid aluminum heat exchanger on the rear panel, eliminating fans and moving parts while a low-distortion input circuit with an advanced safety limiter helps preserve the character of the incoming signal at all levels.

The NXL 24-A MK2’s horn and waveguide system are designed as a vertically asymmetrical line array. The 3-inch driver sits on an asymmetrical waveguide that projects sound accurately to the coverage area without needing to tilt the enclosure, and two NXL columns can be cascaded to extend throw. RCF’s Bass Motion Control and FiRPHASE processing work together to manage woofer excursion, extend low-frequency linearity, and maintain phase coherence so vocals, instruments, and playback feel focused and intelligible even in challenging rooms.

The enclosure is built from high-quality Baltic birch plywood with a road-ready finish, two side handles, and a 35 mm pole insert for mounting on stands or over subwoofers. Four M8 rigging points and four Quick Lock positions support flown and coupled configurations, while PowerCON TRUE1 TOP IN/OUT connectors provide IP-rated, UV-resistant power connections for heavy-duty use. For Chicago DJs, clubs, and production teams that want a slim column with line array behavior, the NXL 24-A MK2 is purpose-built to raise output without increasing visual footprint.

Control Modes for the RCF NXL 24-A MK2

NXL 24-A MK2 keeps the rear panel simple so you can adapt quickly to different roles while internal DSP manages crossover, phase response, and protection. The panel includes an input and link output, preset selector, and volume control so you can dial in behavior without outboard processing.

• Linear: Neutral voicing for stand-alone columns or systems where tonality is shaped primarily at the console or system processor. Ideal for full-range FOH use in clubs, rooms, and corporate events.
• 2 Speakers: A preset aimed at paired or coupled NXL 24-A MK2 configurations. Use this when two columns are working together, either side-by-side or vertically cascaded, to maintain a balanced tonal response.
• High-Pass: Engages a high-pass contour tailored for operation with subwoofers. This shifts the deepest bass to subs and lets the NXL 24-A MK2 focus on mid-bass, vocal, and high-frequency detail while increasing headroom in the column.
• Volume: Main level control for matching the column with other system elements. Behind the scenes, Soft Limiter plus thermal, excursion, and RMS protections help safeguard the transducers and amplifier during high-level operation.

Combined with Bass Motion Control and FiRPHASE, these modes make it straightforward to configure the NXL 24-A MK2 for stand-alone rigs, paired columns, or full systems with dedicated subwoofers.

Asymmetrical Waveguide and Column Line Array Coverage

The NXL 24-A MK2 is designed as a line array column, with a vertically asymmetrical horn that projects sound into the audience area while minimizing unwanted reflections. This horn geometry lets you place the cabinet on a sub or stand without tilting the enclosure, keeping the look clean while still targeting listeners. Two NXL columns can be cascaded to expand coverage when you need more throw or to reach balconies and upper seating.

The 100° horizontal x 30° vertical coverage pattern improves intelligibility in acoustically challenging spaces by focusing acoustic energy where it is needed. For DJs and live engineers, this means mixes that feel more even from front to back, with less emphasis on ceiling bounce and sidewall reflections.

Neodymium Transducers and Two-Way Column Architecture

Inside the cabinet, NXL 24-A MK2 uses four 6-inch high power neodymium woofers for low and mid frequencies and a 3-inch titanium neodymium compression driver for the top end. The neodymium motors keep weight down while maintaining strong motor force, and the titanium dome with Polyimide/Kapton voice coil is designed to handle high power with low distortion.

This two-way column architecture allows the driver and woofers to share the workload efficiently across the 60 Hz – 20000 Hz operating range. The result is a tight low end, defined vocal range, and smooth high-frequency response that works well for speech, bands, and high-energy DJ material.

Bass Motion Control and FiRPHASE DSP Integration

To extend bass performance without sacrificing control, the NXL 24-A MK2 incorporates Bass Motion Control. Instead of relying solely on a conventional high-pass filter, BMC builds a detailed map of woofer behavior and applies a custom algorithm that limits only over-excursions. This approach allows the woofers to reproduce the lowest audible frequencies available within the design while keeping their motion within safe and linear limits.

FiRPHASE is RCF’s FIR-based processing platform, used here to support transparent sound and consistent imaging for listeners throughout the coverage area. Together, Bass Motion Control and FiRPHASE help the NXL 24-A MK2 maintain clarity, punch, and coherence even when driven hard in real-world club, stage, and event environments.

Baltic Birch Construction, Rigging Flexibility, and TOP Power Connectivity

The cabinet is built from Baltic birch plywood with a rugged protective finish and steel grille, designed to stand up to touring use and permanent installation. Two side handles make the tall, narrow enclosure manageable for one or two people during load-in and load-out, and the 35 mm pole insert supports stand or sub mounting.

For rigged systems, the NXL 24-A MK2 offers four M8 mounting points and four Quick Lock positions, allowing installation on truss, brackets, or bespoke hardware using compatible accessories. Power is handled through PowerCON TRUE1 TOP IN/OUT connectors with IP-rated protection and UV resistance, supporting heavy-duty and harsh environment applications that are common in modern entertainment venues and outdoor events.

How to Deploy the RCF NXL 24-A MK2 in the Field

For many shows, a straightforward approach is to mount one NXL 24-A MK2 per side on poles using the 35 mm insert, either on stands or on matching subwoofers. Aim the columns so the 100° horizontal coverage just spans the audience width and let the 30° vertical pattern project toward the listener area rather than ceilings. Start with the Linear preset when most tonal shaping is handled at the mixer or controller.

When building larger rigs, you can cascade two NXL 24-A MK2 columns vertically to extend throw and improve coverage in deeper rooms. Use the 2 Speakers preset to match the voicing to a paired configuration and take advantage of the vertically asymmetrical horn design for coherent coverage. For DJ and live music applications that demand more impact below 60 Hz, pair the NXL 24-A MK2 with suitable subwoofers and engage the High-Pass preset so subs handle the lowest octaves.

In installs or flown applications, use the M8 points and Quick Lock positions with approved hardware and follow RCF guidelines and local rigging regulations. The combo XLR/jack input, XLR output, and +4 dBu input sensitivity make integration with consoles and system processors familiar for engineers and rental techs, while PowerCON TRUE1 TOP simplifies daisy-chaining power between cabinets.

Deployed on poles, coupled as columns, or flown over subs, the RCF NXL 24-A MK2 gives Chicago DJs, bands, and installers a slim line array tool that is easy to position and powerful enough to carry the room.
