SUB 708-AS II
ACTIVE SUBWOOFER
DESCRIPTION
Thanks to the powerful 18” woofer, with 3.0” voice coil, and the 1400Watt 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. 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. 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
