RCF NXL 44-A MK2 Active Two-Way Line Array Speaker

RCF NXL 44-A MK2 High-Output Line Array Column for DJs and Live Sound

The RCF NXL 44-A MK2 is an active two-way line array column engineered to bring big-system performance into a compact footprint for Bands, DJs, Clubs, and Rental Companies. A powerful 2100 W Class-D amplifier drives three 10-inch high-power neodymium woofers and a 3-inch titanium neodymium compression driver, delivering up to 135 dB SPL with a linear 45 Hz – 20000 Hz response. The result is a sleek column that behaves like a line array, with serious headroom and clarity for modern shows.

A vertically advanced waveguide provides controlled 100° horizontal by 25° vertical coverage, accurately projecting sound where it is needed and minimizing unwanted reflections. The NXL 44-A MK2 can be used as a stand-alone column, stacked on a sub, or coupled with a second NXL 44-A MK2 to extend throw and coverage in longer rooms. Dedicated rigging points and quick-lock hardware make it just as comfortable flown or truss-mounted in permanent installations and touring rigs.

Inside the cabinet, RCF’s Bass Motion Control and FiRPHASE processing optimize the interaction between drivers, amplifier, and enclosure. Bass Motion Control manages woofer excursion so the system can reproduce very low frequencies while maintaining stability, and FiRPHASE filtering helps maintain phase coherence and imaging across the audience area. A fanless, convection-cooled amplifier module, Powercon TRUE1 TOP IN/OUT connectors, and balanced combo input with XLR link output support reliable operation in demanding professional environments.

Built from rugged Baltic birch plywood, finished in black with a steel protective grille and side handles, the NXL 44-A MK2 is tuned for the grind of rentals, club installs, and mobile DJ work where the same system may handle weddings one night and live bands the next.

Control Modes for the RCF NXL 44-A MK2

The NXL 44-A MK2 keeps system setup straightforward while still providing the tools needed to adapt the speaker to different configurations. Onboard DSP, a simple preset selector, and clearly labeled controls give DJs, engineers, and system techs predictable results in the field.

• Preset Selector: Rear-panel presets include Linear, 2 Speakers, and High-Pass modes, allowing you to optimize voicing for single-column use, vertically coupled pairs, or systems integrated with subwoofers.
• Level Control: A dedicated volume control makes it easy to match amplifier gain to your mixer, controller, or system processor without compromising headroom.
• Signal and Limiter Management: The input circuit uses a low-distortion design with an advanced safety limiter, working together with thermal, excursion, and RMS protections to maintain the character of the input signal at all operating levels.
• Balanced I/O: A combo XLR/Jack input accepts balanced or unbalanced sources, while an XLR link output feeds additional NXL 44-A MK2 columns or other powered loudspeakers.
• Integrated DSP Platform: Bass Motion Control manages woofer excursion for extended low-frequency performance, and FiRPHASE processing helps maintain time and phase coherence across the listening area.

Line Array Style Coverage in a Compact Column Format

The NXL 44-A MK2 is designed as a line array column, combining a vertically advanced horn with a focused 100° x 25° directivity pattern. This geometry projects sound energy forward while limiting spill onto ceilings and unused areas, which is especially valuable when the cabinet is placed on a subwoofer, stand, or flown position. For longer rooms or deeper audience areas, two NXL 44-A MK2 columns can be cascaded to extend coverage while maintaining consistent tonality.

• Vertically controlled pattern helps preserve clarity in reflective clubs, banquet halls, and live spaces.
• Single-column deployments handle many portable DJ and live music situations with minimal visual impact.
• Cascaded pairs create a scalable alternative to larger line array systems for medium-sized concerts.

High-Power Neodymium Transducers Tuned for Modern Shows

At the core of the NXL 44-A MK2 are three high-power 10-inch neodymium woofers with 2.5-inch voice coils and a 3-inch titanium compression driver on a waveguide. RCF designs and builds these drivers in Italy, tailoring motor structures, cones, and voice coils specifically for the demands of high-SPL portable and installed sound systems. The combination of lightweight magnets and robust voice coils supports strong dynamics with controlled distortion.

• Neodymium motors improve power handling while helping keep cabinet weight manageable.
• Titanium dome and Polyimide/Kapton voice coil in the HF section handle high power with low distortion.
• Woofer design emphasizes fast transient response and heat dissipation at higher currents.

Bass Motion Control and FiRPHASE for Clean, Extended Low End

Bass Motion Control (BMC) rethinks conventional high-pass protection by mapping the woofer’s behavior and creating a custom algorithm that limits only over-excursions. This approach keeps very low frequencies intact without sacrificing stability or introducing unnecessary phase shifts. In parallel, FiRPHASE technology uses advanced digital FIR filters to deliver transparent sound and accurate imaging, maintaining coherent frequency and phase response for listeners across the coverage area.

• BMC allows the NXL 44-A MK2 to reproduce the lowest audible frequencies while preserving woofer control.
• FiRPHASE supports precise, time-aligned reproduction, beneficial for vocals, instruments, and DJ content.
• The overall DSP tuning balances output, protection, and clarity for repeatable results from show to show.

2100 W Class-D Amplifier and Professional Power Infrastructure

The NXL 44-A MK2 is driven by a 2-channel Class-D amplifier delivering 2100 W peak power, 50% more powerful than previous NXL amplifier platforms. The module is mounted to a solid aluminum heat exchanger and cooled by convection, eliminating the need for a fan and the maintenance concerns that come with moving parts. A Switch Mode Power Supply keeps total weight reasonable while delivering the energy required for modern, high-impact audio.

• Power allocation of 700 W peak HF and 1400 W peak LF supports high SPL with control.
• Energy-efficient design reduces excess heat, even during long DJ sets and concerts.
• Designed according to EN62368-1 safety standards for professional audio equipment.

Two side handles simplify carrying and lifting, while eight M8 rigging points, eight quick-lock positions, and a 35 mm pole mount insert offer multiple deployment options. From floor-mounted stacks to flown arrays, the same cabinet can move between touring, rental, and fixed installations with minimal reconfiguration.

• Handles and balanced dimensions make single-person setup more manageable where staffing is tight.
• Rigging hardware supports flown or truss-mounted use with appropriate accessories and practices.
• Shipping dimensions and weight are suitable for organized truck packs and warehouse storage.

How to Deploy the RCF NXL 44-A MK2 in the Field

The RCF NXL 44-A MK2 is built to move quickly between different system roles, from portable DJ rigs to flown arrays. A typical deployment uses a pair of columns over matching subwoofers, with the horn height set at or slightly above audience ear level. The 25° vertical pattern should be aimed so that the primary coverage reaches the back of the room without overshooting into ceilings or unused areas.

• Pole-Mount Over Subwoofers: Use the 35 mm insert to place each NXL 44-A MK2 on a subwoofer pole, aligning the column so the waveguide faces the audience and clears the front line of guests.
• Single or Dual Column Configurations: For shorter rooms, a single column per side with the Linear preset is often sufficient. For extended throw, stack or fly a second NXL 44-A MK2 per side and select the 2 Speakers preset as recommended in the product documentation.
• Flown and Truss-Mounted Arrays: When the system is flown or attached to truss using the M8 and quick-lock points, always follow RCF rigging guidelines and local safety regulations, and verify all load ratings before lifting.
• Integrating with Subwoofers: Use the High-Pass preset when pairing the NXL 44-A MK2 with subs for DJ and live music systems so low-frequency duties are shared appropriately between tops and subs.
• Gain Structure and Limiting: Start with mixer outputs at nominal levels, set the NXL 44-A MK2 level control for typical show volume, and verify that limiters only engage on peaks rather than continuously.

Thoughtful aiming, preset selection, and subwoofer integration turn the RCF NXL 44-A MK2 into a reliable, repeatable front-of-house solution for DJs, bands, and club installs.
