Thanks to the powerful 18" woofer, with 3.0" voice coil, and the 1400-Watt amplifier, the SUB 708-AS II is the perfect tool to increase the low end performance of a portable PA system, both in terms of output and frequency extension. Thanks to 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 perfectly match 12" or 15" satellite speakers. The SUB 708-AS II is the ideal companion subwoofer the RCF ART 3, ART 7 or D-Line Series.
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. Your crowd will be able to live an engaging immersive musical experience.
The RCF cabinets are made of birch plywood coated with a textured black finish. The subs are stackable and light-weight, for easy set-up and tear down, thanks to the ergonomic handles. A pole receptacle allows the use of the box in various configurations. The powder coated 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 operating with high efficiency into a lightweight solution. RCF amplifiers deliver an ultra-fast attack, realistic transient response, and impressive audio performance. 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.
