The Red 50 is the smallest cabinet in the Russell K range but what it gives up in size it makes up for with a huge musical heart. It offers low colouration while exhibiting superb stereo imaging, timing and real energy to the overall musical picture.

Russell K have taken a retro approach to their loudspeaker design but utilise cutting edge technologies to achieve their goals.

Firstly they found that a heavily damped thin wall cabinet works well for the midrange but too much cabinet flex softens the bass response. Their solution is to keep the cabinet walls thin and to use internal bracing shelves to control cabinet flex. The Red series light cabinet vibrates when the drive units are playing but stops when the drive units stop, ensuring near-perfect sound reproduction.

The RED series also shuns internal damping which then allows the cabinet to move in time with the main drive unit for superbly accurate sound reproduction. The use of damping in most current speakers slows down the internal soundwave, making it out of sync with the output of the driver. With Red 50 the cabinet breathes in time with the main drive unit ensuring freedom from time-smear and cabinet distortions.

Finally the finely tuned crossover produces the perfect balance of sound. Russell K have conducted thousands of hours of research into the effect that different crossover types have on the sound. Countless hours have been spent fine-tuning the crossover, adjusting the components, voicing and testing different types of music on various electronics. This is undoubtably a lengthy process but the results speak for themselves with a range of speakers that sound just like the real thing.

The RED series speakers are not supplied with grilles as standard but they can however be ordered separately along with a variety of cabinet/baffle colour combinations!
