The CM20DT 6.5" two-way built-in loudspeaker can be used in 16 ohms or 70/100 volt modes. The high-quality 70/100 volt transformer is equipped with an easy tapping sticker with clear colour indication. The transformer colours are aligned with the cables connecting the Apart Quick Fit connector, a handy installer connector via push terminal. In 16 ohms use, you can connect up to 4 loudspeakers in parallel on each channel of a standard 4 ohms amplifier. The paintable thin edge grille makes CM20DT the ultimate loudspeaker for design interior integration.
