RCF SUB 705-AS II

The RCF SUB 705-AS II is the ideal solution for addressing the lack of low frequencies in portable PA systems. It provides both volume boost and extends the frequency range towards significantly lower frequencies. The built-in digital stereo crossover allows for easy connection of full-range speakers and their use as a mid-high system. The SUB 705-AS is the perfect complement for compact speakers equipped with 12'' to 15'' mid-bass drivers. SPL - High Power
Exceptional power ensures breathtaking levels of acoustic pressure in open spaces and outdoor applications. Integrated DSP
The built-in digital stereo crossover with switchable crossover frequency enables easy use of the SUB 705-AS II as a subwoofer for compact full-range speakers. Compatibility with Professional RCF Speakers
The clever design of the SUB 705-AS II seamlessly integrates with top-of-the-line RCF speakers. The bass reflex design ensures linear and deep sound reproduction, with a 3'' coil minimizing power compression. Deep Bass Response
Featuring two selectable EQ presets, allowing for exceptionally low bass response and precise adjustment of lower frequencies. The SUB 705-AS II is ideal for various applications such as audio installations, live performances, small theaters, spatial acoustics, and lecture halls. Driver
The new high-performance 15'' woofer is the result of RCF's extensive experience in designing and manufacturing compact subwoofers. The advanced design ensures quick response and controlled bass reproduction across the entire range. The speaker in the SUB 705-AS II boasts high sensitivity, excellent linearity, and high power. The suspension shape and waveguide design ensure precise and balanced reproduction. The newly designed basket is highly durable yet lightweight for easy transport. Enclosure
Utilizing modern technologies and integrated DSP, the bass-reflex SUB 705-AS II achieves the same acoustic pressure as a band-pass enclosure without compromising sound quality. The Baltic birch plywood construction is covered with a highly durable epoxy coating, and the speaker is protected by a robust metal grille. With a 35mm socket, mounting a distance rod on the speaker is effortless. Transport is made easier with two convenient handles on the sides of the speaker. Instead of a traditional flat grille design, a different approach inspired by architecture was chosen. This system provides a more balanced grille and better weight distribution, especially when loaded, for example, with stage monitors. The enclosure features non-parallel curves on its sides to optimize sound reflections inside the speaker, preventing unwanted sound wave reflections from the edges that negatively impact sound quality. RCF subwoofers achieve this by using curved sides and pressed corners to mitigate undesirable acoustic effects inside the speaker.
