Control Modes for the RCF KX 515-A

As an active loudspeaker, the RCF KX 515-A integrates amplification and DSP, giving you direct control from the rear panel and extended control over the network via RDNet. The onboard processing manages crossover at 1200 Hz, protection, and voicing, while external control focuses on signal routing and system integration.

• Input and Routing: Accepts balanced or unbalanced input signals via XLR, with pass-through XLR output and RDNet Ethercon connections for networked control.
• Gain and Voicing: Rear panel controls include input sensitivity selection (-2 dBu/+4 dBu), volume, and mode options such as Linear or High Pass to match stand-alone use or integration with subwoofers.
• Bypass and Protection: Bypass options and built-in protections (including excursion management and fast limiters) help safeguard the transducers and maintain consistent behavior at high levels.
• RDNet Integration: Onboard RDNet provides remote access to levels, EQ, and system presets, as well as real-time monitoring of each KX 515-A on the network.
• Power Management: Convection cooling and PowerCON TRUE1 TOP in/out connectors support reliable, fanless operation and daisy-chained power distribution where appropriate.

Compact Point-Source Design with Rotatable CMD Horn

The KX 515-A is built around a rotatable 100° x 70° constant-directivity CMD waveguide that surrounds the high-frequency driver and matches the dispersion of the dual 5 inch woofers. This design maintains uniform coverage through the crossover region and lets you rotate the horn in the field with a simple screwdriver, aligning the pattern with vertical or horizontal mounting as needed.

In real rooms, that level of pattern control translates into better intelligibility and more predictable spill onto walls, ceilings, and seating areas. Whether the cabinet is mounted high and angled down, tucked on a side wall as a fill, or used horizontally under a balcony, the rotatable waveguide helps keep the listening experience consistent seat to seat.

Dual 5 Inch Neodymium LF Section and Titanium HF Driver

Low-frequency and midrange duties are handled by two 5 inch neodymium woofers with 2 inch voice coils, loaded on a custom phase plug to improve efficiency and extend horizontal coverage. Their compact cones deliver fast, articulate response, ideal for speech-heavy content and detailed music reproduction in nearfield and immersive systems.

The high-frequency section uses a 1.75 inch titanium dome compression driver coupled to the CMD waveguide. This combination supports the 70 Hz to 20000 Hz frequency response and provides the clarity and detail needed for vocals, effects, and high-resolution content in demanding installations.

KX DSP Platform with FiRPHASE and Bass Motion Control

At the heart of the KX 515-A is the KX DSP platform, a real-time processing engine designed to deliver high-density, low-latency processing for active speakers and DSP amplifiers. The internal DSP handles crossover, limiters, and alignment while leveraging FiRPHASE and Bass Motion Control algorithms.

• FiRPHASE: Uses proprietary FIR filtering to distribute sound without phase distortions, improving imaging and clarity across the audience area.
• Bass Motion Control: Maps the woofer’s dynamic behavior to generate algorithms that limit over-excursions without relying solely on high-pass filters, preserving phase and frequency response while protecting the drivers.

The result is a compact loudspeaker that behaves like a larger system in terms of linearity and musicality, even at higher output levels where traditional processing often struggles.

RDNet Networked Monitoring and Control Platform

RDNet turns the KX 515-A into a fully networked component within larger RCF systems. Through the RDNet software, engineers can monitor each device, adjust parameters, and build groups or zones from a single interface, whether they are managing a few speakers or a complex distributed system.

The platform includes line array design tools and comprehensive audio measurement capabilities, but it is equally comfortable with smaller installed and portable setups. With RDNet onboard, KX 515-A speakers can be tuned quickly and consistently, making it easier to deliver repeatable results across venues and events.

Rugged Birch Enclosure, Rigging, and Everyday Durability

The KX 515-A enclosure is crafted from high-quality Baltic birch plywood, glued with water-resistant adhesive and coated in weatherproof polyurea paint. This combination provides waterproofing, UV resistance, corrosion protection, and resistance to abrasion and mechanical stress. A solid machined aluminum rear structure works as a heat sink for the amplifier while adding stiffness to the cabinet.

High-strength structural steel rigging hardware, die-cast aluminum handles with ergonomic rubber grips, and waterproof PowerCON TRUE1 TOP mains connectors complete the package. The result is a cabinet designed to handle day-to-day use, from installs that see constant operation to mobile systems that are set up and torn down frequently.

How to Deploy RCF KX 515-A in the Field

Deploying the RCF KX 515-A begins with choosing the right role for its compact, high-output design: as a main system with subs, as distributed fills, or as part of a larger immersive rig. From there, rigging, orientation, and processing are tuned to support the room and application.

• Define the role: Use KX 515-A as a compact main speaker when paired with subwoofers, as front fills or under-balcony coverage, or as surround and height channels in immersive systems.
• Choose mounting hardware: Take advantage of the Quick-fit socket for pole mounting, the top and bottom M10 points, pin hardware, and bracket options to hang or mount the cabinet on truss, walls, or ceilings.
• Rotate the waveguide: Before finalizing installation, rotate the CMD horn so its 100° x 70° dispersion aligns with the chosen vertical or horizontal orientation.
• Connect signal and power: Run balanced audio to the XLR input, connect RDNet Ethercon where networked control is required, and plug mains into PowerCON TRUE1 TOP in/out connectors.
• Set operating mode: Use the rear panel controls to choose Linear or High Pass settings depending on whether a subwoofer is used, and adjust input sensitivity and level for clean gain structure.
• Fine-tune with RDNet: Once the system is powered, use RDNet to monitor status, apply presets, group speakers, and perform final EQ to match the room and program material.

Deployed with thoughtful rigging, horn orientation, and RDNet tuning, the KX 515-A becomes a compact workhorse that delivers precise coverage and impressive output in Chicago venues and mobile rigs.
