RCF SUB 702-AS MK3 - 1400W 12-inch Powered Low Frequency Subwoofer with 2.5-inch Voice Coil in Black Finish

The RCF SUB 702-AS MK3 is a powerful, high-performance 12" active subwoofer designed for live sound applications, offering a deep, rich bass experience. Featuring a high-power ceramic magnetic circuit and a 2.5-inch voice coil, the SUB 702-AS MK3 is powered by a robust 1400W Class-D amplifier. This combination ensures the subwoofer can deliver impressive sound pressure levels up to 129 dB, while maintaining low distortion and exceptional headroom. Ideal for small to mid-sized venues, it is an excellent complement to 8" or 10" loudspeakers, providing extended bass for various applications, including live events, DJing, and more.

The subwoofer's Class-D amplifier is highly efficient, offering ultra-fast attack and a realistic transient response, while its fanless design eliminates noise and enhances reliability. The amplifier features a solid aluminum heat exchanger, providing excellent heat dissipation without any moving parts. Designed for maximum energy efficiency, the subwoofer operates without the need for a cooling fan, making it both quiet and reliable. The amplifier's stereo input circuit includes a low distortion design with advanced safety limiters, ensuring that the true character of the input signal is maintained at all times.

One of the standout features of the SUB 702-AS MK3 is the innovative Bass Motion Control (BMC) technology. This system manages woofer excursion to prevent distortion, even at extremely low frequencies. By removing the high-pass filter and implementing a custom algorithm that only limits over-excursions, BMC allows the subwoofer to handle the lowest frequencies without affecting woofer stability. This results in cleaner, more powerful bass with greater sound integrity and extended linearity.

The cabinet of the SUB 702-AS MK3 is made from Baltic birch plywood, providing a lightweight yet durable structure designed to withstand the rigors of transport and long-term use. The rugged polyurea coating and steel powder-coated grille ensure the subwoofer can handle even the most demanding environments. The subwoofer is equipped with ergonomic handles for easy transport and setup, and an M20 threaded pole mount allows for easy integration with pole-mounted speakers. The frontal vented ports are designed for enhanced efficiency, making this subwoofer a great fit for recessed spaces and tight installations.

On the rear panel, the SUB 702-AS MK3 features several controls, including volume, EQ, polarity reverse, and switchable crossover frequencies. It also includes stereo XLR inputs and outputs for easy integration into any audio system. With its flexible frequency response range (40 Hz - 120 Hz) and maximum SPL of 129 dB, the SUB 702-AS MK3 is capable of delivering deep, impactful bass that enhances the overall sound experience. Whether used for front-of-house applications, as a high-powered floor monitor, or in combination with other RCF loudspeakers in a larger system, the SUB 702-AS MK3 excels in delivering high-quality bass at exceptional levels.
