RCF SUB 705-AS MK III - Active subwoofer for professional sound reinforcement

The RCF SUB 705-AS MK III is a high-performance active 15-inch subwoofer that is ideal for professional use at live events, in clubs, on mobile stages or for DJ performances. With its powerful 1400-watt Class D amplifier module, state-of-the-art DSP technology and innovative Bass Motion Control, it is the ideal tool for sound engineers, musicians and event technicians who rely on uncompromising bass pressure. The SUB 705-AS MK III not only delivers an impressive maximum level of up to 131 dB, but also impresses with a precise, controlled low-frequency range, which noticeably engages the audience.

Thanks to its compact design, the lightweight but extremely robust wooden housing and versatile connection and control options, the RCF SUB 705-AS MK III can be used flexibly - both in permanently installed sound systems and in mobile operation. It is perfectly matched to smaller tops with a diameter of 10 or 12 inches and, in combination, ensures a balanced sound image across the entire frequency spectrum.

Sound engineers worldwide rely on RCF because the products meet the highest demands in terms of both sound and technology.

RCF has set standards in the development of active subwoofers in particular.

The products are designed and manufactured in Italy, with every single component designed for maximum efficiency and quality.

Technical details of the RCF SUB 705-AS MK III

The RCF SUB 705-AS MK III is equipped with a 15-inch woofer with a 3-inch voice coil that operates in a bass reflex cabinet. The system offers a frequency response of 40 Hz to 120 Hz and generates a maximum sound pressure level of up to 131 dB - enough power to ensure powerful bass reproduction even in larger rooms or outdoors.

At the heart of the system is the 1400 watt Class D amplifier module, which is renowned for its efficiency and reliability. With 700 watts RMS power, the SUB 705-AS MK III delivers stable performance with low heat generation, which is supported by passive convection cooling - without any annoying fan noise.

The integrated DSP section offers a switchable high-pass and low-pass filter, soft limiting, EQ and comprehensive protection functions (thermal and RMS-based). The volume, phase, crossover and EQ can be conveniently adjusted using the rear controls. The switchable X-OVER preset, which can be selected between 80 Hz and 120 Hz, is particularly practical, as is the polarity reversal for optimum phase alignment in the setup.

The subwoofer has balanced XLR inputs and outputs, which makes it easy to integrate into existing PA systems. The output signals can be output either as a line or high-pass signal, which offers maximum flexibility when connecting tops.

The construction of the housing is made of high-quality Baltic birch plywood, which is coated with a durable, scratch-resistant polyurea lacquer. A sturdy M20 threaded flange, side carrying handles and a protective metal grille with acoustic fabric insert complete the professional design.

Why it's worth buying the RCF SUB 705-AS MK III

The RCF SUB 705-AS MK III is the ideal choice for anyone looking for maximum bass performance in a compact space. Its impressive output power, coupled with intelligent DSP control and ease of use, makes it the perfect tool for live music, club events, DJ performances or permanent installations.

Its high-quality workmanship guarantees a long service life - even with frequent transportation and intensive use. The flexibility of the configuration allows it to be perfectly matched to different setups and speaker systems. Whether as an extension for existing systems or as the centerpiece of a new PA setup: this subwoofer impresses with its technical sophistication, sound quality and ease of use.

In addition, RCF's Bass Motion Control is an exclusive technology that analyzes and actively regulates the movement of the woofer to ensure more precise bass reproduction without distortion - a real added value for demanding audio professionals.
