High Quality RCF HDM 45-A Active Powered Speaker System

RCF HDM 45-A Active 2200W 2-way 15" Powered Speaker with RDNet:
The HDM 45-A speaker boosts the performance with a top-quality two channel amplifier, RDNet networked management, RCF precision transducers, the FiRPHASE processing, and a rugged cabinet. While being one of the most powerful speakers in composite material in its category, it delivers clear, detailed and smooth sound from low to very high levels, with low distortion and fast transient response.

High Quality Active 45-A Powered Speaker System

The HDM concept is inspired by the touring industry, packing in an elegant and lightweight cabinet the maximum reliability and strength for intensive use on the road. Perfect as a main front of house speaker in PA systems, high-powered floor monitor, or unobtrusive infill system when combined with the RCF HDL System speakers.

  • 2200 Watts two-way power.
  • Innovative DSP Processing with FiRPHASE.
  • 1.5" Titanium Compression Driver, 4.0" v.c. Neodimium.
  • 15" Neodimium Woofer, 3.5" v.c.
  • 650 Hz crossover point for perfect vocal reproduction.
  • 90°x60°, wide dispersion constant directivity horn.
  • RDNet compatible.
Tour sound

The concept of this unique speaker derives from the touring industry, bringing in a compact cabinet all the experience of RCF professional sound. The RCF Team always has the performer's needs at the forefront of the design in order to create new lines of speakers with renewed features, improved sound clarity and definition and even lighter weight systems. D-LINE represents the latest evolution in the active loudspeaker technology with a revolutionary design and sound. Every detail has been carefully studied in order to offer musicians and professionals the perfect tool to amplify their performance, night after night. High quality materials, precise manufacturing, careful assembly and extensive quality control procedures complete the groundbreaking design work of the RCF R&D team. The vocals are natural, the sound is clear at longer distances, the spl power is stable at very high levels.

The high power transducers equipping D-LINE have been representing for decades the ultimate performance, the highest power handling and the most advanced technology in the professional and touring industry. All Compression drivers and Transducers are precision built taking advantage of RCF's superior moulding, assembly technologies and a wealth of professional knowledge and experience dedicated to achieving extremely high standards. The high power woofer delivers extremely accurate punchy bass, the custom made compression driver offers a transparent midrange and extreme fidelity.

RCF Class-D power amplifiers technology packs huge performance operating with high efficiency into a lightweight solution. D-LINE amplifiers deliver ultra fast attack, realistic transient response and impressive audio performance. The integrated DSP manages crossover, equalisation, soft limiter, compressor and dynamic bass boost. Each input board presents both XLR/jack balanced inputs, XLR output link, mic/line switch, volume and a switchable EQ Mode (Flat/Boost). The amplifier features a solid mechanical aluminium structure which not only stabilize the amplifier during transportation but also assist in the heat dissipation. All the D-LINE amplifiers presents SMPS power supply section in order to produce maximum output and minimum transportation weight.

The reflex porting has been resized to offer a better efficiency. HDM 45-A is equipped with a top handle and two side handles with rubber handgrip for greater portability. At the bottom a rugged steel pole mount has been installed in both models. The cabinet shape will allow to use the speaker in the standard configuration as well as in stage monitor model. Four M10 threaded inserts are provided for optional mounting hardware in Installed Sound Applications.

RCF RDNet: Networked Control and Much More

RDNet is a robust management network and control platform for small, medium and large arena-sized sound systems, as well as complex and extended installations. Based on a proprietary network protocol, RDNet provides intuitive control and monitoring of every connected device/object in the RCF audio system. Each device has DSP to address specific presets or modifications of parameters to single or groups of objects. A network user can change level, delay, EQ (linear phase FiR as well) and other settings, including advanced subwoofer configurations. RDNet is not only designed for loudspeakers-you can control parameters and routing of multiple RCF devices, such as digital matrixes or amplifiers.

Superior Compression Drivers

The ND940 Compression Driver in pure Titanium with a 4 inches voice coil allows a crossover point at only 650 Hz. This allows a better impulse response, fast decay and superior efficiency. Lightweight and powerful, RCF neodymium drivers are a reference in performance and reliability.

Direct Drive Technology

The voice coil features a high-temperature kapton former. The assembly process takes advantage of the RCF proprietary Direct Drive technology. The diaphragm's suspension has been designed following extensive studies aimed at minimizing distortion and extending low frequency range.

Potent Woofer

The low-frequency transducer is a high-power 15" neodymium woofer with a 3.5" voice coil, delivering a punchy bass. Reproduction of the mid-bass frequencies is accurate, transparent and free from distortion.

Powerful Class D Amplifiers

Constant linearity from very low-level signals to the maximum amplifier output. A 32-bit floating-point DSP with 48 kHz processing takes care of:

  • 2-way crossover and transducer alignment.
  • 8 programmable equalizations.
  • Programmable output time delay.
  • Input Sensitivity reduction.
  • Soft limiter for very high signal inputs.
  • RMS monitoring and transducer protection.
  • Input noise reduction.

A specially developed algorithm takes care of the frequency dependent soft limiter offering to the listener the same linearity of the system, from very low-level signals to the maximum amplifier output.

Rental Proof

D Line cabinets are molded with a special polypropylene composite material designed to dampen vibrations even at maximum volume settings. From molding to the final texture, D-LINE offers maximum reliability and strength for intensive use on the road. The advanced vented architecture offers high efficiency and low distortion. The speaker is equipped with a top handle and two side handles with rubber handgrips for greater portability.

High Demand Applications

The multi-purpose cabinet shape will allow every D-LINE model to be used in the standard configuration as well as in stage monitor mode. Two M10 and three M6 threaded inserts available for optional mounting hardware. This makes the speakers perfect for use in mounted or flown situations. When used on top of a SUB Series the HD speaker becomes an incredibly powerful PA system.

New Perspective on Linearity

RCF speakers are designed using a proprietary and advanced FiR filtering technology, conceived to deliver transparent sound, absolute clarity and perfect stereo images to the listener. The special FiRPHASE filters allow to achieve coherent distribution of sound for all listeners without phase distortions, ensuring minimum latencies to the system.
