The optimum positioning of the speakers depends on their use:

On-Top Speakers for Dolby Atmos:

One AEH 400-ATM is placed on top of each of the existing front speakers (Fig. 2). If this positioning is not
desirable or the area available is not sufficient, the Atmos speakers are placed in the immediate vicinity of
these locations.

When using four AEH 400-ATM’s and direct emission speakers in the surround sound area (no dipoles), the rear Atmos speakers are placed on top of the surround sound speakers or as close as possible to them (Fig. 2).  If this is not possible, the rear Atmos speakers are placed near the rear wall at the same height and the same distance from each other as the front pair. The baffles must always be set at an angle to point into the room.

Please ensure for this operating mode that the switch on the connector terminal is in the “Atmos” position shown on the type plate.  The Magnat AEH 400-ATM has a matching size and look to fit perfectly on top of the Cinema Ultra front loudspeaker LCR 100-THX.

Ceiling Speakers for Dolby Atmos:

Two AEH 400-ATM’s are secured to the ceiling of the room using VESA brackets (100x100mm, M4). The
optimum position is slightly in front of the listening position (approx. 80° in relation to the listener) and the distance between the two ceiling speakers should correspond to the distance between the left and right front speakers (Fig. 3a/b).

When using four AEH 400-ATM’s as ceiling speakers, these are also placed at the same distance from each
other as the front speakers, but further to the front and rear. The optimum location in relation to the listening position is at an angle of 45° and 135° in relation to the listener (Fig. 4a/b). The baffles must always be set at an angle towards the listener. Please ensure for this operating mode that the switch on the connector terminal is in the “Direct” position shown on the type plate.

For acoustic reasons, we would advise against mixed operation of indirect emission (ceiling reflection) and
direct emission.

Wall or Ceiling Speakers for Other Uses:

The AEH 400-ATM is also suitable as an add-on speaker for other audio formats and as a presence or wide speaker for modern AV amplifiers and receivers. With regard to the optimum positioning for these operating modes, please see the user guides and manufacturer recommendations for the respective devices.

For the AEH 400-ATM, we generally recommend using the VESA bracket for wall or ceiling mounting in these operating modes. Please make sure that the baffles of the add-on speakers are always pointing into the room towards the listener and that the switch on the connector terminal is in the “Direct” position shown on the type plate.
