Step # 2
After cutting the floor opening
(approx 4” x 12”) where desired, measure and mark
beam for mounting vertical brackets as shown. Ideal
spacing between brackets is 16” -19”. Be sure that
bottom of bracket plate is about ½” above bottom
beam edge.
Step # 3
Install vertical brackets using (4) #6 drywall
screws. Note: Vertical brackets mount to the outside
of the beam and are directly across from one another
allowing for a clear span on the inside. Install across
beams 1 pc of angle iron. Push onto the threads.
Use (1) 5/16” washer, (1) 5/16” lock washer and
(1) 5/16” lock nut per side. Do both sides.
Thread securely.
Step # 4
Slide the UTF subwoofer, foam side up, into place and install second angle
iron as above. Tighten all 4 nuts progressively until the front side foam compresses
about 1/8”.
Step #1
Cut the opening in the floor to fit your desired floor vent grille.
The floor opening must be at least as large as the size of the UTF port:
Step #2
Port Opening Dimensions:
UTF 10 – 2.5” h x 11.5” l
UTF 12 / UTF 12 LE – 2.5” h x 12.5” l
Step #3
