Thanks to the powerful 18” woofer, with 3.0” voice coil, and the 1400-Watt 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 birch plywood enclosure is coated with black, heavy-duty, textured epoxy and the front is protected by a strong, powder-coated metal grille. The cabinet features a 35 mm pole mount socket and two comfortable recessed side handles. Every detail is developed in order to optimize acoustical performance and ensure easiness of transport.
SUPER POWERFUL BASS REFLEX
Thanks to the use of modern technologies and an integrated DSP, our bass-reflex loudspeakers provide the same sound pressure of a band-pass, without compromising sound quality.
CURVED PROFILE FOR A BETTER SOUND
Two sides show a distinctive inward curve. The reason behind this original design choice 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.
HEAVY-DUTY FRONT GRILLE
Instead of being simply flat, the grille shows a distinctive design with 3 sides. This arch-inspired structure adds resistance to the whole system, creating a more balanced distribution of forces when the stage monitor is subject to stress and pressure, as often occurs during tours and live performances.
ONLY 4 INVISIBLE SCREWS
This charming cabinet is firmly anchored by 4 screws only. The screws are carefully tighten and hidden into small built-in holes, for a sleek and discreet aesthetics of the cabinet. Invisibile bolts are also less subject to wear and tear.
ULTRA-RESISTANT STEEL POLE MOUNT
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.
PERFORATED HEX GRILLE
The hexagonal shape of the holes is chosen with the purpose to maximise the empty space on the grill, thus making sound propagation clearer, with less absorption and reflection. The perforated hex grille allows the sound to propagate freely, with less disturbance if compared to circles or other shapes. At the same time these grilles are particularly strong and rugged, ideal for use on the stage.
INNOVATIVE GRILLE FIXING
The grille is fixed by specialized technicians in our Italian factory, with an innovative component that avoids grille vibration: a small isolating rubber element placed between the cabinet’s edges and the grille, in order to avoid undesidered acoustical interference due to the grille’s oscillation.
A special transparent-to-sound foam backing on the inside of the grille ensures protection from dust and humidity.
2 ERGONOMIC SIDE HANDLES
Two ergonomic recessed handles are positioned on the sides of the speaker.
