Unpacking & Installing the L150i
Your new Wisdom Audio Sage L150i in-wall speaker is a substantial piece of
equipment. Please exercise caution when unpacking your L150i to ensure that
you do not strain yourself from its (perhaps unexpected) weight.
Caution! Do not attempt to lift your L150i by yourself. Unpacking these
speakers is easy for two people, but it is unwise for a single person to
attempt doing so.
Do not attempt to lift your L150i while bending or twisting from the
waist. Use your legs for lifting, not your back.
Always stand as straight as possible and keep the L150i close to your
body to reduce strain on your back.
The loudspeaker comes “telescoping” boxes (two five-sided boxes, one of
which fits snugly inside the other). Gently roll the box over so that its bottom is
facing up. Then carefully cut the tape along the bottom of the box on all four
sides. Roll the box over again so the bottom is on the floor, and lift off the top.
With one person at each end, carefully lift the speaker components out of the
box and lay them on a soft surface (carpet or similar).
There are three major pieces involved in a single L150i loudspeaker:
• the Uni-Grip™ in-wall mounting systems (two included)
• the high operating pressure bass module
• the planar magnetic midrange/treble module
Note that the two Uni-Grip™ frames for the L150i are not interchangeable, due
to differences in the pattern of threaded holes used to attach the planar and
woofer speaker modules to the frame of each Uni-Grip™. Pay close attention to
the labeling on each, which indicates “Planar Section, Top” or “Woofer Section,
Top” respectively.
In most cases, the planar magnetic section of the L150i will be inside of the
woofer sections. In addition, the two sections must be within approximately 5”
of each other and should typically flank either side of a stud.
Because of the magnitude of the bass energy of which the L150i is capable, it is
strongly recommended that the walls into which the L150i is installed are rein-
forced and as strong as feasible.
In new construction or remodeling applications, we recommend framing in
dedicated spaces that are between 10-11 inches wide for the woofer sections,
just slightly wider than the 9.52 inches required by the Uni-Grip™ frame. If the
wall is going to be skim-coated with plaster after construction, consider using
3
⁄
4
-inch plywood or MDF for the wall for superior strength. (This approach is
advantageous for the woofer sections; the reaction mass of the planar section is
extremely low, and does not require this level of reinforcement.)
1. Determine the area for the speaker installation and locate the
cutout guide using push pins to secure it in place. Ensure that the
template is plumb using a bubble level or similar. Note: Make cer-
