The Russell K Red 150 is anything but ‘just another floorstander’. Like its standmount siblings, the Red 150’s cabinet is undamped.
The first thing that struck me on listening to the Red 150s, was how good the timing is, and how vividly they portray detail. Percussion is breathtaking: natural, fast, tactile, and rhythmic to a degree few peers can approach.
