High quality transducers

Woofers and compression drivers are precision built taking advantage of RCF’s assembly technologies and a wealth of professional knowledge and experience dedicated to achieving extremely high standards.

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.

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.
