Final Installation in New
or Existing Construction
1. If it is possible to lay a batt of insulation
into the ceiling cavity do so. Remember
to use equal amounts of insulation for
each loudspeaker.
2. Check the position of the Impedance
jumper on the crossover PC board.
Choose the 4 ohm position if you are
using an amplifier capable of driving a
4 ohm load and you have only one pair
of speakers connected. Otherwise, use
the 8 ohm position
(See Figure 15).
3. Separate the loudspeaker end of the two-
conductor speaker-wire run to free at
least 2" of each conductor. Strip 1/2" of
insulation from the end of each conduc-
tor.
(See Figure 16).
4. To connect the stripped end of one con-
ductor to the black terminal, push down
on the black terminal lever. Insert the
stripped end of the conductor into the
opening on the black terminal. Release
the pressure on the lever. Pay attention
to the markings on the wire. Now
connect the other wire to the red termi-
nal. Each loudspeaker must be connect-
ed to the amplifier in the same way. If
unsure, see “Speaker Phase” located on
the following page.
5. The DS8.3 and DS8.5 feature a separate
frame assembly which installs with four
clamps or mounting “dogs” which hold
the frame in place. The dogs are tight-
ened via four front-baffle screws.
Tighten the dogs by turning the screws
clockwise. DO NOT OVER-TIGHTEN
THESE SCREWS. Over-tightening the
clamps may make the grille difficult to
install.
(See Figure 17).
NOTE: The screws will turn easier if you
“prime” them first. Before installing each
speaker, turn the screws in and then turn
them back out to their original positions.
6. Holding the loudspeaker in the palm of
your hand, insert the loudspeaker into
the frame, twist clockwise to lock.
(See Figure 18).
7. Direct the tweeter. The tweeter is direct-
ed by gently pushing on the edge of the
tweeter housing.
(See Figure 19). It will
move 17° in any direction. For critical
listening, point the tweeter to
