Recommended Amplifier Power
For satisfactory performance, we recom-
mend an amplifier with a power rating of
10 to 150 watts for the DS8.3; 10 to 175
watts for the DS8.5. Curiously, most
speakers are not damaged by large
amplifiers but by small amplifiers. If your
system is playing loudly, a small amplifier
will run out of power very quickly. When
an amplifier runs out of power it creates
damaging “clipping” distortion. A large
amplifier will play at the same volume
without distorting. See the section
on operating the loudspeakers for more
information about clipping distortion.

Installation Considerations
New Construction Bracket serves as a
“hole saver” when drywall has not
been applied. It is not necessary when
retrofitting to existing ceilings.
Knockout wire tie allows the wire to be
secured to the bracket throughout the
new construction process. It knocks
out cleanly when the loudspeaker is
installed.
New construction wings
instantly snap into the
bracket without screws.
Wings are scored for
easy size trimming.
Brackets and wings
attach to the ceiling joists
with nails or screws.
Dogs swivel 90°, then
clamp the loudspeaker
frame to the drywall.
Frames are molded with a
slight texture to assure
good paint adhesion.
Mounting screws tighten the
“dogs”, clamping the loud-
speaker to the drywall.
Rust-proof aluminum grilles make the DS
series perfect for moist environments.
