auxiliary speakers

The only hitch to this simulator is that several auxiliary speakers, ideally six, are needed to project the different environments into a room.

(Like Pink Floyd, the Cure also deployed auxiliary speakers around the arena for selective stereo effects.)

The hitch is that several auxiliary speakers are needed to project the simulated ambiance into the living room, and each of these speakers requires its own channel of amplification.

Among the many unusual capabilities of the Bose system is that it can be set up with auxiliary speakers to play different kinds of music in different parts of the house simultaneously.

If the auxiliary speakers for surround-sound are to be concealed in the wall, a different kind of central control unit is needed, capable of accommodating whatever speakers you choose for wall mounting.

The remote control can also be extended throughout the house, with somewhat less elaborate auxiliary control panels placed in various locations, such as bedroom, kitchen or den, or wherever auxiliary speakers might be installed.
