Russell K Red 120 Floorstanding Loudspeaker

The Russell K Red 120 floorstanding loudspeaker is the latest addition to the Russell K loudspeaker family, offering high performance but in a more compact cabinet. With a depth of only 190mm, this box is easy to place and does not dominate one’s living space. The sound is typical Russell K: fast, natural, and with a deep, controlled bass with perfect timing.
