The RD series of loudspeaker drivers offer the systems designer the advantages of a thin-film, line-source transducer with very high performance potential for fixed installation sound reproduction. Unlike most exotic driver types, the RD Series models feature unmatched bandwidth, power handling and ruggedness, as well as the ease of an almost entirely resistive load to the amplifier. All models in the RD Series feature linear, push-pull Ceramic 8 motors linearly driving a polyester diaphragm whose moving mass is actually less than the air load. The bandwidth of the RD Series drivers is extraordinarily large, and is usable from as low as 150Hz to beyond audibility. Program power handling of the RD40 driver is 100 watts. The diaphragm is protected within a chassis made of three layers of heavy gauge, self-reinforced steel.
Specifications: • Power handling: 50 watts RMS/200 watts max • Nominal impedance: 5 ohms • Re: 5.0 ohms • Frequency range: 150-18,500 Hz • SPL: 88 dB 1W/1m • Net weight: 18.4 lbs. • Dimensions: 40" L x 4-11/16" W x 1-1/2" D.
