RCF has announced the introduction of the SUB 8008-AS, a new double 18-inch-loaded active subwoofer with a vented port design for a range of sound reinforcement applications.
The transducers utilize a high-power ceramic magnetic circuit combined with a 4-inch voice coil designed to deliver very high yet balanced performance in three specific areas: maintenance of a consistent, high integrity magnetic flux gap, very low distortion, and efficiently integrating the magnetic circuit in a minimum weight design. The T-pole design optimization generates the minimum amount of flux modulation in the magnetic assembly during typical voice coil movement within the gap.
Meanwhile, the class D power amplifier manages currents of up to 4400 watts in providing the audio energy to deliver sound pressure levels up to a stated 137 dB, with a frequency response of 30 to 120 Hz. The fast attack with accurate power handling is managed with high efficiency, producing a very low heat loss for silent and fan-less cooling.
Rear panel controls include 12 presets, crossover frequency, polarity switch, deep/punch selection, cardioid, and output delay settings. The tour-ready, rugged all-wood cabinet with scratch-resistant polyurea coating is designed to be easy to carry and secure for installation. Two M20 threaded pole mounts on the top and side allow the cabinet to be used in vertical or horizontal configurations. The heavy-duty polyurea coating, the powder-coated metal grille, and the rugged structure of the cabinet withstand long-term use and transportation.
A separate housing for the amplifier is designed to enhance component efficiency and reliability. An acoustically transparent sound foam backing on the inside of the grille helps ensure protection from dust and humidity. Due to the frontal vented ports, the subwoofer can also be used in recessed spaces.
