Legendary transducers

Superior compression drivers
The ND840 Compression Driver in pure Titanium with a 3” voice coil allows a crossover point at only 800 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’’ woofer with a 3.0’’ voice coil, delivering a punchy bass. Reproduction of the mid-bass frequencies is accurate, transparent and free from distortion.

Powerful class D amplifiers

RCF’s Class-D power amplifier 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 amplifier features a solid mechanical aluminum structure which not only stabilises the amplifier during transportation but also helps the fan-less heat dissipation. All the D-Line amplifiers present SMPS power supply section in order to produce maximum output and minimum transportation weight.

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 offer 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.
