RCF SUB 708-AS II Active Subwoofer

The SUB 708-AS II is the perfect speaker to increase the low end performance of a portable PA system, in terms of both output and frequency range. It features a powerful 18" woofer, with a 3.0" voice coil and a 1400w amplifier. With the built-in digital stereo crossover (DSP) with adjustable crossover frequency it can be easily and quickly set up as a satellite speaker system. The SUB 708-AS II is built to perfectly complement the RCF ART 3, ART 7 or D-Line series.

Overview:

RCF subwoofers are the first choice of many sound engineers, thanks to the very high SPL levels at very low frequencies, smaller dimensions compared to the competitors, self-powered design, and impressive size/weight to SPL output ratio.

The RCF cabinets are stackable and light-weight, for easy set-up and tear down. A pole receptacle allows the use of the box in various configurations. The front grille integrates a special transparent-to-sound foam backing on the inside to further protect the transducers from dust.

RCF's Class-D power amplifier technology packs huge performance and high efficiency into a lightweight solution. The amplifier features a solid machined aluminium structure which not only stabilises the amplifier during transportation but also helps the fan-less heat dissipation. All the amplifiers present SMPS power supply section to produce maximum output and minimum weight.
