Trimless, high-end, in-ceiling speaker for wall installation with a defined nominal dispersion of 80°. This sophisticated 3-way system was developed as a front speaker (l, r, centre) for home audio systems and media rooms. The 6.5" low-mid woofer driver has a 1" tweeter with waveguide and de:shape coaxially aligned in front of it, which ensures that sound is emitted in a controlled manner with constant directivity characteristics. Thanks to its finely tuned crossover, the DE-X 300 CDR has a highly linear frequency response with a powerful base range and natural sound pattern, even at high levels. Due to its directivity, the DE-X 300 CDR can reproduce speech very clearly even in rooms with long reverberation times.

Der DE-X 300 CDR comprises three parts (assembly frame, speaker insert with internal crossover and front grille) and is installed from the front through the installation opening.
