RCF | SUB15AS / SUB18AS
Following the great success (and thankfully improved availability) of the SUB15AX and SUB18AX, RCF has now developed these cabinets without Bluetooth and digital DSP. This was done simply because not everyone needs Bluetooth or digital processing — some just want a solid, reliable, and slightly more affordable RCF subwoofer.
POWERFUL CLASS D AMPLIFIERS
With 2,200W power, our Class-D amplifier is able to manage extreme sound pressure levels with an ultra-fast attack, realistic transient response, and very low heat loss. So energy-efficient that there’s no need for a cooling fan. The amplifier is attached to a solid aluminum heatsink in the rear of the cabinet with no moving parts. The stereo input circuit with crossover features a low distortion design with an advanced safety limiter, maintaining the true character of the input signal at all levels. RCF amplifiers are designed according to EN62368-1 for maximum safety and present a Switch Mode Power Supply section joining high efficiency with minimum weight.
BASS MOTION CONTROL
The advanced woofer excursion management increases linearity and
improves bass punch with a radical new approach. BMC extends the
lowest audible frequency without affecting the transducer’s stability,
limiting over-excursions for greater reliability and superior performance at high volume levels.
TOUR-READY WORKHORSE
The subwoofer is suitable for a wide range of live sound applications. The rugged all-plywood cabinet is easy to carry and stack, due to its light-weight. All are equipped with ergonomic handles with rubber grips for easy set-up and tear down. The M20 threaded slot on the top allows the cabinet to support speakers with a pole mount. The heavy-duty polyurea coating, the powder-coated metal grille, and the rugged structure of the cabinet withstand long-term use and transportation.
