Hertz Mille Pro MPX 690.3

This superb set of 6 X 9's feature high sensitivity as well as high power handling capability (230 Watts Peak). The acoustically transparent basket minimises any chance of back wave colouration or unpleasant resonance which can degrade the sound in traditional 6 X 9 speakers. The tweeter and super-tweeter faceplate is designed to optimise dispersion particularly important for 3-way coaxial speakers to maintain an articulate balanced sound across all frequencies.
