Mordaunt-Short DSB 208

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.
