The SUB 705-AS mk3 is a portable 15" high-power active subwoofer for live sound applications. It features a state-of-the-art transducer with a high-power ceramic magnetic circuit and a powerful Class-D amplifier that delivers sound pressure levels up to 131 dB with exceptional headroom. Designed as the ideal complement for 10" or 12" loudspeakers, it provides outstanding performance in any application. Rear panel controls include volume, EQ, polarity, and crossover frequency selection. The rugged all-wood cabinet with scratch-resistant polyurea coating makes it durable, easy to carry and install securely. With its versatility, sound quality, and high power output, the SUB 705-AS MK3 is perfect for small to mid-sized venues and portable applications.

Bass Motion Control

When searching for an extended bass with enhanced performance, RCF engineers found a way to remove the high-pass filter, replacing it with a forward-thinking approach. Introducing BMC (Bass Motion Control), the newly advanced woofer excursion management feature. The speaker equipped with BMC can handle the lowest audible frequencies without affecting the woofer stability, with extended linearity and better sound integrity.

The BMC method works by creating a complete map of the dynamic behavior of the woofer, to generate a custom algorithm that only limits over-excursions. This gives total freedom of signal reproduction to the transducer. When high-pass filters normally protect the woofer motion from becoming destructive but change the phase behavior, the new BMC algorithm breaks conventional rules.
