The SUB 708-AS II, is a compact active sub enclosure with a 1,400W powerful digital amplifier and an 18” woofer. It can easily be transported and is quick and easy to set up. It is designed to integrate into RCF or other professional speaker systems. The bass reflex design guarantees a deep, linear power response, while the 3" voice-coil design woofer offers the minimum of power compression.

The SUB 708-AS II is equipped with a new generation of 1,400-watt digital amplifiers that produce high output, low distortion and an incredibly natural sound. The amplifier features a solid mechanical aluminum structure that not only stabilizes the amplifier during transportation, but also assists in 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 high-power 12" 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 optimization. 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 these subwoofers, sound waves don’t hit the sides because of the slightly concave profile.

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.
