RCF KXW 4-A Wide Coverage Dual 10 Powered Speaker

RCF KXW 4-A Wide Directivity Active Two-Way Speaker

The RCF KXW 4-A is a compact, flexible, high-output active two-way speaker that couples 134 dB max SPL with a rotatable 100 x 50 degree waveguide for precise, repeatable coverage in both vertical and horizontal layouts. The low-frequency section uses dual 10 inch neodymium woofers with 3.0 inch voice coils in a bass-reflex design, matched to a neodymium compression driver with a 4.0 inch titanium dome on the dedicated horn for coherent, controlled directivity.

A 3200 W two-channel Class-D amplifier with high-end AD/DA conversion drives the system, while onboard DSP with FiRPHASE and Bass Motion Control (BMC) maintains clarity, phase coherence, and low-frequency linearity at any level. Integrated RDNet networked management gives engineers deep remote monitoring and control over each cabinet, and the weather-resistant Baltic birch plywood enclosure with polyurea coating, machined aluminum rear structure, steel rigging, and powerCON TRUE1 TOP mains connectors makes the KXW 4-A fully ready for touring, rental, and demanding fixed installations.

Expanded Detail on the RCF KXW 4-A

Advanced Class-D Amplification and DSP Platform

The KXW 4-A uses high-powered Class-D amplifiers that are tailored to each transducer band, delivering clean power with efficient heat dissipation and low distortion. The design keeps power consumption under control while preserving dynamic impact. A next-generation DSP engine manages crossover, equalization, dynamics, and time alignment in real time, using high-end AD/DA conversion to maintain audio quality from input to output.

Coherent 100 x 50 Degree Directivity

The dedicated waveguide is engineered to provide a consistent 100 x 50 degree coverage pattern, enabling multiple KXW 4-A cabinets to work together as a system with excellent control of directional characteristics. In challenging rooms with reflective surfaces, the controlled directivity greatly improves intelligibility and helps keep energy off unwanted areas, making it easier to achieve a clean mix.

Precision High- and Low-Frequency Transducers

The high-frequency section uses a 4 inch pure titanium dome compression driver with a neodymium magnet assembly designed for high flux density, low distortion, and consistent response over time. The motor structure uses an ultralight edge-wound aluminum voice coil, an optimized phase plug, and a copper ring to enhance linearity and power handling. The low-frequency section employs two 10 inch hypervented neodymium woofers from the Precision Transducers line. These drivers feature a robust magnetic structure, a newly designed aluminum basket, and an advanced ventilation system that cools the voice coil, magnet assembly, and basket. The M-roll surround and carefully tuned spider deliver accurate cone control, high output, and low power compression.

Tour-Ready, Weather-Resistant Enclosure

The cabinet is constructed from high-quality Baltic birch plywood, assembled with water-resistant adhesive and finished in a weatherproof polyurea coating. This combination provides strong protection against moisture, UV exposure, abrasion, and mechanical impact. A solid machined aluminum structure on the rear panel acts both as a heat sink for convection cooling and as an added reinforcement for the enclosure. The structural steel rigging hardware offers a high safety factor for flown arrays, while die-cast aluminum handles with ergonomic rubber grips make day-to-day handling more efficient. Waterproof powerCON TRUE1 TOP mains connectors further support use in demanding environments.

Bass Motion Control and FiRPHASE Processing

Bass Motion Control maps the woofer behavior in detail and applies a custom algorithm to manage over-excursion, letting the KXW 4-A reproduce very low frequencies more cleanly than traditional high-pass filter approaches. Instead of simply cutting low-frequency content to keep the woofer safe, BMC preserves frequency and phase characteristics while still protecting the driver. FiRPHASE processing uses advanced FIR filters to align phase and amplitude, improving imaging and delivering a coherent listening experience with minimal latency across the coverage area.

How to Deploy the RCF KXW 4-A in Your System

The RCF KXW 4-A is designed for flexible deployment in touring, rental, and fixed installation environments. Its compact form factor, rigging hardware, and rotatable horn make it equally at home as a main system element, sidefill, delay loudspeaker, or part of a distributed installation.

• Left/right mains or clustered systems Use KXW 4-A cabinets as primary left and right mains, or in clustered configurations, taking advantage of the 100 x 50 degree directivity and rotatable horn to match coverage to the audience area.
• Flown arrays and hanging configurations Integrate the KXW 4-A into flown systems using the array fittings and threaded rigging points (2 x M10 on the top and 2 x M8 on each side). The controlled directivity and high SPL capability make it suitable for flown arrays in concert, theater, and corporate setups.
• Ground-stacked and pole-mounted setups The 35 mm pole-mount insert and compact footprint allow fast ground-stacked configurations on top of subwoofers or dedicated stands. This is ideal for mobile DJs, rental companies, and portable production rigs.
• Installed sound and distributed systems The weather-resistant Baltic birch cabinet, polyurea finish, and robust hardware support use in installed applications where long-term durability is essential, such as clubs, performance venues, houses of worship, and multipurpose spaces.
