The ADPC1 allows the MD1 or MD1R to be mounted in the ceiling.

The Architectural In-Ceiling loudspeaker will be the MD1(R)C and it opens up a world of possibilities for this application. This ETL™ based loudspeaker produces no acoustic energy in the ceiling structure and greatly reduces vibration while increasing dynamics and dispersion. Coherent back EMF improves the amplifiers operation with remote volume controls and distribution transformers. The MD1(R)C distributes all of the drivers acoustic output into the room and is not affected by nearby reflection surfaces. The single driver and elimination of diaphragm breakup assures that the nearby wall reflections are the same as the on-axis output. The MD1(R)C ceiling speaker has the remarkable ability to respond to lower bass and higher treble frequencies simultaneously while dispersing the sound to the entire room. This level of performance eliminates the need for wall speakers with solid depth, width and height imaging achieved from the ceiling. speaker has the remarkable ability to respond to lower bass and higher treble frequencies simultaneously while dispersing the sound to the entire room. This level of performance eliminates the need for wall speakers with solid depth, width and height imaging achieved from the ceiling. The MD1(R)C can be mounted in any ceiling and if not to high right above flush mounted HDTV sets while clearly tracking the on screen sound. It makes the sound image bigger than the picture itself for truly wonderful involvement in the action. The MD1(R)C provides excellent off axis imaging providing the proper phantom for center image to all viewers. The center channel can be used in surround systems but phantom is good even for this application. With a full 40-20kHz response, this is the true solution for music and home theater integrated into a invisible system that won’t transmit sound into the surrounding structures. The MD1(R)C can be specified for any ceiling location with consistent natural sound for all rooms. Subwoofers are an option with this speaker, which reproduces the full range of sound in its acoustic output. The MD-1(R)C can be used with any quality amplifier or surround receiver with up to 100W. The MD-1(R)C has been measured to produce dynamic levels over 100db and with an even diffusion of the sound this results in less need for blasting it. One very important aspect of any speaker is the ability to resolve low-level detail. This is the factual definition of dynamic range not how loud it gets and with the MD-1(R)C you can maintain low levels and hear all of the dynamics, vocal and detail.

The MD1(R)C requires a 8.625” (219.075mm) cutout with a 10.31” (262mm) overall bezel diameter. The depth is 4.83” (122.85mm) from the front mounting surface. The front bezel has a flush edge (<1mm) offset a maximum of .34” (8.65mm) from the surface at grille center.
