DC265 / DC365 INSTALLATION

Mounting Considerations

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.

Sound Coverage and Speaker Placement

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.

DC265 / DC365 COVERAGE & SPEAKER PLACEMENT

Sound Coverage and Speaker Placement

Audio Imaging: Ceiling or wall speakers can be used as pairs for stereo or used in
multiples for 5.1 to 7.1
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.
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)

Listener

Equidistant Example

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.

DC265 / DC365 COVERAGE & SPEAKER PLACEMENT

Sound Coverage and Speaker Placement

When possible, try to reduce the distance of your speaker from the audio source to achieve
the best audio results. The optimum wire run should be no longer than 30 feet for the most
favorable results. If you must run wire longer than 30 feet, we recommend using larger
wire of 12 or 14 gauge.

Among the factors to consider in the planning of your speaker placement is that the front
of the speakers should be free from such obstructions as furniture or built in architecural
features. High and midrange frequencies will be absorbed by fabric, carpet, curtains and
soft furnisings. Walls and hard floors will reflect sound waves.

Regardless of the speaker model (ceiling or wall)
closer then 3' from adjacent or intersecting walls.

IMPORTANT:

The DC265 is not magnetically shielded. Avoid mounting speakers closer than 20” from
a video monitor or TV screen. After installation, if any video or TV screen distortion is
detected, the video monitor or TV must be moved beyond the effect of the magnet motor.
The magnets will distort and discolor the screen and could cause permanent damage to the
picture tube.

Multiple pairs of speakers placed in strategic locations within your coverage area can be a
fundamental solution when designing a system that requires large coverage.

Keep in mind that wire must be run to the location of the speakers. Walls, studs, ducts
and joists in your home may be difficult to get around when wiring your speakers, so
understanding your home's construction and properly planning your design is important.
An example is a home constructed of block with limited wall depth. This would present a
problem for inwall installation and wire management.
