Russell K Red 120 Precision Audio Loudspeaker System

De Red 120 is de nieuwste luidspreker van Russel K. en biedt hoge performantie in een compactere klankkast. Met een diepte van slechts 19cm is deze box makkelijk te plaatsen en domineert ze leefruimte niet.

Het geluid is typisch Russel K. snel, natuurlijk en een diepe gecontroleerde bas met perfecte timing.
