FIGURE 5: "Mirror Image" Tweeter Wiring
Surrounds: Because the surrounds were designed as “dipoles” the two tweeters are connected out of phase
with each other. The “in-phase” tweeter (when the surround is placed in the room) should be facing forward
toward the left, center and right speakers. The “out of phase” or reverse polarity tweeter should face the back
of the room. Because of this you need to build a “left” and “right” surround speaker. The surrounds should be
wired as a “mirrored image” of each other (Fig.5). To keep things straight (during room placement), it is a
good idea to put a label on the terminal cup side of the cabinet indicating which tweeter is “in-phase”. The
“in-phase” tweeter should be wired positive to positive and negative to negative. The “out of phase” tweeter
should be wired positive to negative and negative to positive. The Audax tweeter uses green paint to indicate
the positive terminal. The single woofer should be wired “in-phase”(positive to positive and negative to
negative). Install the drivers using the #8 (large) screws for the woofer and the #6 (small) screws for the
tweeters. Tighten the screws only until the drivers are flush with the baffle of the cabinet. Do not over
tighten the screws!

5)Room Placement
Room placement for the home theater
system is fairly straight forward. The
dipole surrounds can either be placed on
speaker stands or mounted on the wall
15"-20" from the ceiling with the woofer
firing upward toward the ceiling at an angle.
If you plan on using speaker stands, the
side with the terminal cup becomes the
bottom and you should use the rubber feet
to make room for the speaker wire. No
matter how you mount them, just
remember the “in-phase” tweeter (when the
surround is placed in the room) should be
facing forward toward the left, center and
right speakers (Fig.6). The “out of phase”
or reverse polarity tweeter should face the
back of the room. No home theater
system is complete without a quality
subwoofer. We recommend using the
#300-739 10" Titanic Subwoofer with this
Home Theater System. Also designed by
Vance Dickason, the 10" Titanic Subwoofer
produces quick, accurate and powerful
bass. The Titanic Subwoofer System will
produce more apparent bass when it is
placed near a corner. Choose a location
that is close to the A/V components and
place it at the front of the listening area.
