2 DC265 / DC365 INSTALLATION Sound Coverage and Speaker Placement Dual architectural speakers are designed to work within nearly all interior decorating schemes where in-wall or flush mounting is feasible. Wall mounted and ceiling mounted speakers should be installed away from corners or intersecting walls, and directly adjacent to the listening area. This placement gives the best audio imaging. Position your speakers symmetrically for best results. Your design approach should take in to consideration the intended use of your speakers. Sound coverage and audio imaging should be viewed as seperate goals . Speaker Coverage: This installation may be desired if the speakers are intended to be used as an intercom based music system. Typical ceiling speakers should not be spaced greater then two times (x2) the ceiling height. Measure floor to ceiling and multiply by two. An example using this rule and the table below: If you had an 8 foot ceiling, a pair of speakers would be spaced 16 feet apart, which would result in a coverage area of 500 square feet.

3 DC265 / DC365 COVERAGE & SPEAKER PLACEMENT Au dio Imaging: Ceiling or wall speakers can be used as pairs for stereo or used in multiples for 5.1 to 7.1 multi-channel applications. Ideally you should place the stereo or front left and right speakers as directionally balanced as possible to the primary listening area. A common rule is to position the front speakers so that the distance between the listening position and the wall is 1.5 times the distance between the two speakers, but the speakers can be further apart if you desire a wider sound stage. In a typical audio/ video multi-channel setup, the listening position is directly facing the video source (TV or Monitor) and the center channel is on a direct plane with the listener. If the listener is positioned 15 feet away from that video source, then the optimal distance between the left and right speakers would be 22.5 feet apart (15'x1.5) . Sound Coverage and Speaker Placement Listener The speaker imaging decreases rapidly the further the listener is from the speakers, so an equidistant speaker arangment for multi-channel installation is desired for the best results. Try to equalize the speakers distance so the listener is basically in the middle of the sound stage. Equidistant Example
