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.
The SUB 708-AS II is equipped with a new generation of 1400 Watt Digital Amplifiers that produce a very high output, an extremely low distortion and an incredible natural sound. The amplifier features a solid mechanical aluminium structure which not only stabilize the amplifier during transportation but also assist in the heat dissipation.
The input board includes stereo XLR Inputs (Balanced/unbalanced), stereo XLR Link/XOVER outputs, volume control, Xover switch, phase switch. Three status LEDs - Limiter / Signal / Status - are provided for monitoring the system. The new high-power 18-inch woofer is the result of the latest refinement in years of RCF experience in compact active subwoofer design and manufacture, providing a fast and controlled reproduction of the bass frequency range.
The reason behind the original design of the cabinet’s distinctive inward curve is related to sound optimisation. In a cabinet with a standard design, sound waves reflect on the cabinet’s edges, thus creating undesired effects of absorption and disturbance or decreasing sound coverage. In our SUBs sound waves don’t hit the sides because of the slightly concave profile with moulded edges that helps avoiding all acoustical drawbacks.
Two ergonomic recessed handles are positioned on the sides of the speaker. Thanks to the integrated steel pole mount, the SUBs can be easily combined with another speaker with a few simple moves. The use of steel instead of plastic makes the whole system particularly reliable and robust, thus allowing to choose a heavier monitor without the risk of damage.
