The “quadral Platinum M 4” features an extraordinary price / performance ratio. Developed by quadral, the “Ri-Com” tweeter combined with the mid-range drivers equipped with an aluminum membrane generate powerful yet high-definition sound. The elegant finish of the hefty housing in high-gloss white or high-gloss black visually reinforces the premium status of this loudspeaker. Highlighted in the STEREOPLAY 12/09 trade publication, a top ranking in their tests proves that good design can also generate outstanding sound.
