SUB 705-AS II
ACTIVE SUBWOOFER
DESCRIPTION
The SUB 705-AS II is a compact and powerful bass reflex subwoofer. It is
equipped with a 15” high power woofer with 3” voice coil, powered by
a 1400 Watt digital amplifier in a robust plywood housing with deep and
punchy tuning for a powerful bass. Thanks to the built-in digital stereo
crossover (DSP) with adjustable crossover frequency, it can be easily and
quickly set up with a satellite speaker. The SUB 705-AS II easily combines with
12” and 15”, ideal for RCF ART and D-Line Series.
The SUB 705-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 15-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.
