c.
Mark four hole locations for the mounting bracket, based on a. and b. above. Use the bracket as a
template, and make sure that it is straight and plumb by using a bubble level.
d.
Choose appropriate fasteners. The Alpha weighs 65 lbs (32kg), and each fastener will need to be
rated for 30 pounds (15kg) each, to account for vibration. For sheetrock walls, we suggest using
EZAnchors and their associated screws. For Concrete walls, we suggest using good quality wall
anchors and screws. For plywood surfaces, wood screws in a size 10 (6mm) and above will work
well.
e.
Holding the speaker from the top bar and the top lip of the woofer tunnel, pick it up and carefully
place the two bars into the slots of the hanging bracket. Make sure that the speaker is centered and
that the fingers of the hanging brackets are straight.
f.
Speaker aiming: The speaker can be aimed up or down by selecting the right length of stud
between the hanging bars and the speaker back panel (see picture above). Alphas are typically
shipped with a smallest stud at the bottom, and the next size up at the top, for a down angle of 5
degrees, which matches most installation requirements. You can custom-order the speaker angle
setting, or you can change the studs to adapt to the installation conditions. Contact Grimani
Systems to order the studs.
