QuickStart Installation Guide:
The installation of the SUB1 can be broken down into several simple steps. The
installation of the SUB1 is intended to be a pre-construction process as it
requires access to the space within the ceiling joists. The SUB1 fits within
standard ceiling joists that are spaced between 12” to 24” OC (305mm to
610mm) and requires a minimum of 8” (203mm) of height to fit the box plus the
L brackets.
1. Identify subwoofer locations. Identify the surface to be mounted, and
the size and shape of the finished grille.
2. The SUB1 band-pass must be located within 12” to 24” (305mm to
610mm) of the grille location for the snorkel.
3. Mount the L-brackets to the joists where the band-pass cabinet will be
located as detailed above.
a. The brackets should be positioned to support the front and
rear of the cabinet.
b. If necessary, use the SUB1 shipping foam to remove excess
space inside the joists.
4. Position the band-pass cabinet between the joists so that you have
access to the speaker binding posts and port tube outlet.
a. The port tube “Bass Snorkel” can be repositioned from the
front to the side of the cabinet if access to the port tube will
be obstructed.
b. The port tube connection and the block off plate are held in
plate with screws and can be easily.
5. Connect the speaker wires to the binding posts on the side of the
cabinet.
6. Connect the “Bass Snorkel” port tube to the cabinet with steel
clamp.
7. Connect the “Bass Snorkel” to the mounting platform with the
neoprene rubber under steel clamp. The clamp should fit snug before
being tightened. If not, flip the clamp and check again. The inside of the
clamp has slightly smaller inside dimensions for the side to be used
with the snorkel and slightly larger inside dimension for the side to be
used with the mounting plate.
8. For Gypsum installations, mud using the Sanding Guide. Once the
sanding is complete, push firmly on the sanding shield to break any
adhesion to surrounding surfaces. Remove the screw in the center of
the shield under the tape. This will expose the paint shield. Do not
remove the paint shield.
9. For Gypsum installations, use the Paint Shield to allow the paint to fill the inside corner where the grille will be placed.
10. Adjust the grille depth for a flush mount to the finished surface using the Paint Shield as a guide.
NOTE: The SUB1 port tube clamp is not accessible from within the room and must be tightened before drywall is finished.
