Installation (cont.)

DRYWALL OR OTHER HARD SURFACES:

1 Be sure you know the location of the ceiling joists before cutting the speaker

opening. Cut a 14-1/4" circular hole where the CSUB will be installed. Use the

included template as a guide.

2. Make electrical connections to the snap-lock input connector and then plug it into

the CSUB (see Speaker Wiring section).

3. Install terminal cover using the supplied screws. If using conduit, refer to the

Terminal Cover section of this manual.

4. Place the CSUB in the ceiling cut-out. To help

properly place the CSUB in the ceil-

ing, the front of the CSUB is engraved

with guide arrows for “14-1/2" Joist

Space” (see Product Diagrams, #6). Use

these guides for this installation.

Important:

Be certain to position the subwoofer so

that the engraving “14-1/2" Joist Space”

aligns perpendicularly between the studs.

Failure to do so may result in the clamps

being unable to swing out far enough to

seat the speaker properly.

5. Using an electric screwdriver with the clutch at a low setting, tighten each clamp

screw until the clamps are just snug against the ceiling surface. Once all four

clamps are snug on the ceiling, the four clamp screws should be tightened with

the next clutch setting or with a hand screwdriver. Do not over-tighten

clamps.

6. Before installing the grille, make sure you have selected the proper power setting

on the front panel rotary switch. Refer to the Selecting Power Levels section for

instructions on selecting the power level. Install the grille as indicated in the

Speaker Grille Installation & Removal section.

Mounting clamps extend to joists.

14-1/2 Inches between ceiling joists.
