Professional RCF Active Line Array Speaker

The RCF HDL 6-A is designed as an active line array module, meaning the loudspeaker incorporates its own amplification and signal processing. This provides a complete powered loudspeaker solution without requiring a separate external amplifier for each module.

The integrated two-channel Class-D amplifier provides 1,400 W peak power and 700 W RMS power. The amplifier architecture is divided between the low-frequency and high-frequency sections, with 1,000 W peak and 500 W RMS allocated to the low-frequency section and 400 W peak and 200 W RMS allocated to the high-frequency section.

This integrated amplification allows the RCF HDL 6-A to operate as part of a professional line array system with efficient power management and dedicated processing for the individual transducers.

For touring companies, rental companies, production teams and installation professionals, an active line array module can simplify system design and deployment by combining loudspeaker components, amplification and DSP processing into one enclosure.

High-Power Dual 6-Inch Neodymium Woofers

The RCF HDL 6-A features two high-power 6-inch neodymium woofers designed to provide strong low and mid-frequency reproduction within the compact line array enclosure.

The two woofers use 2-inch voice coils and are arranged symmetrically within the cabinet. This symmetrical design contributes to the overall acoustic performance of the system while maintaining a compact physical format.

The use of neodymium transducers also helps reduce the overall weight of the enclosure compared with designs using heavier conventional magnetic assemblies. This is particularly valuable in touring and flown line array applications where equipment weight can influence transportation, rigging and system deployment requirements.

The dual 6-inch configuration provides the RCF HDL 6-A with the low-frequency and mid-frequency capability required for professional sound reinforcement while allowing the cabinet to remain relatively compact.

High-Performance Neodymium Compression Driver

For high-frequency reproduction, the RCF HDL 6-A incorporates a neodymium compression driver with a 1.7-inch voice coil.

The compression driver is mounted to a precision 100° x 10° waveguide designed to provide controlled high-frequency coverage.

This configuration is intended to provide clear and detailed reproduction of vocals, instruments and other high-frequency content while maintaining the controlled directivity required for line array applications.

Clear Vocal and Musical Reproduction

One of the key requirements of a professional line array system is the ability to provide clear speech and vocal reproduction while maintaining enough output for music and live performance.

The RCF HDL 6-A is designed to provide detailed vocal reproduction and dynamic musical performance through the combination of its high-frequency compression driver, dual 6-inch woofers and DSP processing.

The 100° horizontal coverage provides wide sound distribution, while the 10° vertical coverage helps create the controlled vertical dispersion expected from a line array module.

This makes the HDL 6-A suitable for applications where consistent coverage across an audience area is required.

131 dB Maximum SPL

The RCF HDL 6-A provides a maximum sound pressure level of 131 dB at 1 metre.

This high output capability allows the module to be used in professional sound reinforcement environments where strong acoustic output is required.

The available SPL, combined with the controlled coverage and integrated DSP, makes the RCF HDL 6-A suitable for live concerts, events, festivals, touring systems and other professional applications.

When multiple HDL 6-A modules are combined into an array, the system can be configured to provide greater coverage and output for larger audiences and venues.

65 Hz to 20 kHz Frequency Response

The RCF HDL 6-A has a published frequency response of 65 Hz to 20 kHz.

This frequency range provides coverage across the majority of the audible spectrum required for professional full-range sound reinforcement.

The HDL 6-A can be used as part of a larger system with a dedicated subwoofer when extended low-frequency reproduction is required. RCF specifically identifies the HDL 12-AS as a suitable flyable bass complement for the HDL 6-A array system.

Using the HDL 6-A together with an appropriate subwoofer can provide a more complete full-range system for applications requiring substantial low-frequency output.

Advanced DSP Processing

The RCF HDL 6-A incorporates a powerful digital signal processor designed to manage crossover functions, phase correction, limiting and protection.

The DSP operates with 48 kHz, 32-bit floating-point signal processing.

This processing architecture allows the loudspeaker system to optimize the interaction between the low-frequency woofers and high-frequency compression driver.

Digital processing is an important part of modern active loudspeaker design because it allows the manufacturer to precisely manage the response and protection characteristics of the system.

For professional users, integrated DSP also means that essential loudspeaker processing is already incorporated into the system, reducing the need for additional external processing equipment.

FiRPHASE Signal Processing

The RCF HDL 6-A incorporates RCF FiRPHASE signal processing technology.

FiRPHASE processing is designed to provide precise phase alignment and optimize the system’s acoustic response.

In a line array application, accurate phase behavior is particularly important because multiple loudspeaker modules operate together as part of a larger acoustic system.

The processing applied within the HDL 6-A is designed to help maintain consistent acoustic performance while providing the clarity and definition expected from a professional RCF line array.

Professional 100° x 10° Coverage

The RCF HDL 6-A provides a horizontal coverage angle of 100 degrees and a vertical coverage angle of 10 degrees.

The wide horizontal coverage allows the system to distribute sound across a broad audience area, while the controlled vertical coverage supports the directional characteristics required for line array applications.

When multiple modules are combined, the vertical configuration of the array can be selected according to the venue and coverage requirements.

Proper array design and aiming are important for achieving consistent coverage across the intended listening area.

Professional Line Array Deployment

The RCF HDL 6-A is designed to be used as part of a line array system.

The integrated array fittings allow multiple modules to be mechanically connected for professional deployment.

This provides production companies and system designers with the flexibility to build arrays according to the size of the venue, audience coverage requirements and desired acoustic performance.

Line array systems are commonly used in professional touring, concerts, festivals and large event environments because they can provide controlled sound distribution over long audience areas.

The compact size of the HDL 6-A makes it particularly suitable for applications where a smaller line array format is preferred.

Integrated Rigging Hardware

The RCF HDL 6-A incorporates integrated array fittings designed to support line array deployment.

Integrated rigging hardware allows the modules to be connected into an array without requiring a separate external frame for every configuration.

Professional rigging should always be carried out according to the manufacturer’s approved procedures, load limits and safety requirements.

The integrated hardware contributes to the practical nature of the HDL 6-A by allowing the loudspeaker to be incorporated into professional flown line array systems.

Compact and Lightweight Design

One of the important characteristics of the RCF HDL 6-A is its compact and lightweight construction.

The module weighs approximately 11.6 kg, making it relatively easy to transport and handle compared with larger professional line array enclosures.

The enclosure measures approximately 237 mm high, 470 mm wide and 377 mm deep.

The combination of compact dimensions and low weight can be particularly useful for touring productions, rental companies and installations where transportation and deployment efficiency are important considerations.

The use of neodymium transducers contributes to the lightweight design while maintaining the performance expected from a professional loudspeaker system.

PP Composite Cabinet

The RCF HDL 6-A uses a PP composite cabinet designed for professional use.

The enclosure is engineered to provide a strong and practical housing for the transducers, amplifier and processing electronics.

The cabinet includes two rear handles to assist with handling and transportation.

This connectivity allows the HDL 6-A to be incorporated into professional signal chains used by sound engineers, production companies and installation teams.

PowerCON IN and OUT

The RCF HDL 6-A features PowerCON IN and OUT connections for professional power distribution.

The PowerCON connections allow power to be distributed through compatible professional loudspeaker configurations, helping simplify cabling in multi-module systems.

When deploying multiple loudspeakers, power distribution should always be designed according to the manufacturer’s electrical specifications and applicable safety requirements.

Professional Protection

The integrated DSP system includes thermal and RMS protection.

The loudspeaker also incorporates a soft limiter designed to help protect the system during demanding operation.

Protection processing is particularly important in professional sound reinforcement because loudspeakers can be subjected to high output levels for extended periods.

The protection system works together with the amplifier and DSP architecture to help maintain reliable operation under demanding conditions.

HF Correction

The RCF HDL 6-A includes an HF correction control within its processing section.

This provides additional flexibility for adapting the high-frequency response of the system to the requirements of the application.

The appropriate setting can depend on the acoustic environment, array configuration and desired system response.

Professional sound engineers can therefore make adjustments as required during system configuration and optimization.

Touring and Live Concert Applications

The RCF HDL 6-A is well suited to touring and live concert applications where a compact but powerful line array system is required.

Touring productions often need equipment that can provide high output while remaining manageable for transportation, rigging and deployment.

The HDL 6-A’s relatively low weight and compact enclosure can make it practical for these applications.

Multiple modules can be combined to create larger arrays according to the requirements of the production.

For larger systems, the HDL 6-A can be paired with appropriate RCF subwoofer systems to provide additional low-frequency extension and output.

Festival and Event Production

Outdoor festivals and large events often require sound systems capable of covering wide audience areas while maintaining consistent sound quality.

The RCF HDL 6-A provides a 100-degree horizontal coverage pattern and controlled 10-degree vertical coverage, making it suitable for professional array configurations designed for these environments.

Production companies can configure multiple modules according to the required audience coverage, venue size and system design.

The integrated amplification and DSP also help simplify the system by reducing the number of external amplification and processing components required.

Corporate Events and Conferences

The RCF HDL 6-A can also be used for corporate events, conferences, presentations and large indoor gatherings.

Clear speech reproduction is especially important in these environments.

The high-frequency compression driver and precision waveguide are designed to provide detailed high-frequency reproduction, helping the system reproduce speech and vocals clearly.

For larger corporate events, multiple HDL 6-A modules can be deployed to provide consistent sound distribution across the audience.

The system can also be integrated with microphones, digital mixing consoles, wireless microphone systems and other professional audio equipment.

Theatre and Performing Arts

The compact form factor of the RCF HDL 6-A makes it suitable for certain theatre and performing arts applications where controlled sound coverage is required.

The system can provide vocal clarity, musical reproduction and wide horizontal coverage while maintaining a relatively small physical footprint.

Depending on the venue and installation requirements, the HDL 6-A can be deployed as part of a flown array or other professional sound reinforcement configuration.

Rental Company Applications

The RCF HDL 6-A is a practical option for professional rental companies that require flexible and transportable line array equipment.

Rental systems are frequently used for concerts, corporate events, festivals, weddings, conferences and private events.

A compact active line array module can simplify inventory management because amplification and DSP processing are integrated into the loudspeaker.

Rental companies can combine multiple modules to build systems suitable for different event sizes.

The lightweight design can also help with equipment handling and transportation.

Installation Applications

The RCF HDL 6-A can be considered for permanent and semi-permanent professional sound reinforcement installations where its acoustic characteristics and physical configuration are appropriate.

Possible applications include entertainment venues, performance spaces, event halls and other professional audio environments.

Before installation, system designers should evaluate the venue, coverage requirements, mounting method, electrical infrastructure and applicable safety regulations.

The integrated array fittings provide flexibility for professional deployment, while the compact cabinet allows the system to maintain a relatively small visual and physical footprint.

HDL 12-AS Subwoofer Integration

For applications requiring additional low-frequency output, RCF identifies the HDL 12-AS as an ideal flyable bass complement for the HDL 6-A array system.

Combining HDL 6-A modules with an appropriate RCF subwoofer can provide a more complete full-range sound reinforcement system.

The subwoofer can handle the lower frequency requirements while the HDL 6-A modules focus on midrange and high-frequency reproduction.

This type of system configuration is particularly useful for concerts, touring productions and large events where strong low-frequency performance is required alongside clear and controlled main system coverage.

System Design and Array Configuration

The performance of a line array depends not only on the individual loudspeaker module but also on the overall array configuration.

The number of modules, vertical splay, aiming, system height and subwoofer configuration can all influence the resulting coverage.

For this reason, professional system design should take the venue and audience area into account before deployment.

The RCF HDL 6-A provides integrated array fittings and controlled directivity to support professional array configurations.

System engineers can therefore configure the loudspeaker according to the requirements of the production rather than relying on a single fixed installation arrangement.

Sound Quality for Professional Applications

The RCF HDL 6-A is designed to provide a combination of output, clarity and controlled coverage.

The dual 6-inch neodymium woofers provide low and mid-frequency reproduction, while the 1.7-inch voice-coil compression driver handles the high-frequency range.

The DSP system manages the interaction between these components and provides crossover, phase correction, limiting and protection.

The result is a professional active line array module designed for demanding sound reinforcement applications.

Whether used for music, speech or a combination of both, the HDL 6-A provides the flexibility required by professional production environments.

Efficient Professional Workflow

An active loudspeaker system can simplify the workflow for production teams because amplification and signal processing are integrated into the loudspeaker.

Instead of transporting separate amplifiers for each loudspeaker module, an active system can reduce the number of external components required.

The integrated DSP also means that the loudspeaker’s processing is already matched to its transducers.

For touring and rental companies, this can help simplify setup and reduce the amount of external processing required in the signal chain.

Professional Power and Performance

With 1,400 W peak power and 700 W RMS total amplification, the RCF HDL 6-A provides substantial amplification for its compact size.

The low-frequency section is rated at 1,000 W peak and 500 W RMS, while the high-frequency section is rated at 400 W peak and 200 W RMS.

This two-channel amplification architecture allows the system to provide dedicated power to the individual frequency sections.

Combined with the DSP processing and professional transducers, this provides a complete active line array solution.
