DSB 208
Low distortion bass-and mid-frequency transducer.
Mordaunt-Short's
bass-and mid-frequency transducer, the DSB208, is a versatile high performance
unit designed for the accurate reproduction of programme material at realistic
sound levels.
By
combining a long-throw voice coil, linear suspension, critically damped cone
and compliant roll surround, the DSB208 shows to greatest advantage when the
unit is used with advanced amplifiers of high power; nevertheless, the acoustic
efficiency of the unit is such as to enable it to enhance the output of quality
amplifiers even of low power ratings.
