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.

Please check your intercom owners' manual to determine the correct impedance loading
for multiple speakers.
