Recommended Amplifier Power
For satisfactory performance, we recom-
mend an amplifier with a power rating of
10 to 100 watts for the DS6.3; 10 to 150
watts for the DS6.5 and the DS6.7.
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 quick-
ly. When an amplifier runs out of power it
creates damaging “clipping” distortion. A
large amplifier will play at the same vol-
ume without distorting. See the section on
operating the speakers for more informa-
tion 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 speaker 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 speaker
frame to the drywall.
Frames are molded with a
slight texture to assure
good paint adhesion.
Mounting screws tighten the
“dogs”, clamping the speaker
to the drywall.
Rust-proof aluminum grilles make the DS
series perfect for moist environments.
