The DE Plan 200 ST inside® is a special version of DE Plan 200 ST designed to be invisibly installed in furniture and wall panels. The speaker is glued onto the backside of furniture or panels made of wood, MDF or similar materials and directly excites through these surfaces. To do this, the recessed mounting area is milled into the rear surface to a wall thickness of 3 mm. The surface is activated without an intermediate membrane, which makes DE Plan 200 ST inside extremely efficient and gives it an extensive, linear frequency range.

de:shape: the membrane of the DE Plan 200 ST inside has an optimized contour with a calculated distribution of distance between the edge and the high frequency driver (patent pending). This results in unprecedented audio performance and extremely accurate sound reproduction.

The elaborately tuned crossover ensures a warm, transparent acoustic pattern. The DE Plan 200 ST is ideally suited to small rooms or zones where only one speaker is required. A wide dispersion angle of 180° ensures that sound is distributed homogenously throughout the room.

The reproduction characteristics depend very much on the material in which the speakers are installed and the acoustics of each room. As a result, our system controllers, DSP power amplifiers or at least a multiband equalizer should always be used to achieve the best sound pattern.
