SUB 702-AS II

SUB 702-AS II
ACTIVE SUBWOOFER
DESCRIPTION
Housing a 12” woofer, the SUB 702-AS II, is a very compact active sub
enclosure and features a 1400 W powerful digital amplifier. It is the ideal
complement to 8” or 10” speakers, creating small but powerful satellite
systems with outstanding performance. Thanks to its compact size it can easily
be carried and is very quick and easy to start using the built-in digital stereo
crossover (DSP) with adjustable crossover frequency to connect the satellite.
The SUB 702-AS II is designed to integrate seamlessly into RCF professional
speakers. The bass reflex design guarantees a deep, linear power response
while the 2.5’’ voice coil design woofer offers the minimum of power
compression. SUB 702-AS II is the perfect match for 8”, 10” or 12” satellite
speakers. It is also the ideal companion subwoofer for the RCF ART 3, ART 7
or D-Line Series.
The SUB 702-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 12-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.
