Fostex 6301N/B - Powered Loudspeaker with Unbalanced Jack Input

The Fostex 6301 N/B is a 20 watt Class-D powered loudspeaker with unbalanced jack input and a 4" driver. The 6301 first entered the market in 1982 and became the standard active monitor speaker in broadcast and production facilities. This compact loudspeaker has now been re-designed with the latest D-class power amplifier and a new driver unit featuring an energy saving “auto stand-by” function.
