    The SUB 705-AS II woofers feature high sensitivity, excellent linearity and very high power handling capabilities. M-roll surround and spider design offer great linearity and precise reproduction. The newly designed basket offers superior strength and improved weight for easier transportation.
    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 inch and 15 inch tops, ideal for RCF ART and 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.
    Super Powerful Bass Reflex
    Thanks to the use of modern technologies and an integrated DSP, RCF 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 the RCF SUB 705-AS MK2, sound waves don't hit the sides because of the slightly concave profile with moulded edges that helps to avoid 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. 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.
    Innovative Grille Fixing
    The grille is fixed by specialised technicians in RCF's 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 undesired acoustical interference due to the grille's oscillation.
