COMPATIBLE WITH RCF PROFESSIONAL SPEAKERS

The SUB 708-AS II is designed to integrate seamlessly into RCF professional speakers. The bass reflex design guarantees a deep, linear power response while the 3’’ voice coil design woofer offers the minimum of power compression. SUB 708-AS II is the perfect match for 12” or 15” satellite speakers. It is also the ideal companion subwoofer for the RCF ART 3, ART 7 or D-Line Series.

DEEP BASS SOUND

Two selectable equalisations to experience the extremely deep response and precise low frequency control.

These attributes make it the perfect tool to increase the low-end performance in a raft of situations - including portable and installed audio-visual systems, live sound, small theatres, houses of worship and surround sound presentations - both in terms of output and frequency extension.

LINK/XOVER OUT SWITCH

The output link is flat when the switch is OFF (the output signal is the same as the input signal), or is high passed when the switch is ON (to connect a satellite speaker).

XOVER SWITCH

This switch sets the crossover frequency of the output at 80 Hz or 120 Hz.

PHASE SWITCH

This switch reverses the phase of the output signal.

POWER MAIN SWITCH

The power switch turns the AC power ON and OFF.

 


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.

 
dsp

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.

 
dsp

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.

 
dsp

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.

 
dsp

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.

 
dsp

FOAM BACKING

A special transparent-to-sound foam backing on the inside of the grille ensures protection from dust and humidity.

 
dsp

2 ERGONOMIC SIDE HANDLES

Two ergonomic recessed handles are positioned on the sides of the speaker.
