Trimless, in-ceiling speaker with a 35° downwards-facing beam direction. The DE-X 300 FR is a front speaker (l, r, centre) that has been specially designed to not obstruct the line of sight of viewers or the screen in home audio systems and media rooms. The speaker features an angled 5.25" low-mid woofer driver with a 1" tweeter with waveguide and de:shape coaxially aligned in front of it and a second 5.25" low-mid woofer driver in the box. This gives the DE-X 300 FR a main directional axis of 35° on the vertical plane. Thanks to its precise balance and defined dispersion angle of 80°, the DE-X 300 FR has a natural sound pattern, even at high levels, and can reproduce speech very clearly even in rooms with long reverberation times.

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