The RCF SUB 708-AS II is a powerful 18" subwoofer with a peak power of 1400W and an RMS power of 700W. This professional subwoofer is the ideal complement to 12" and 15" speakers, especially the RCF ART and D-Line Series. 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 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. 3 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. The SUB's 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.
