1.  Check ceiling area for concealed obstructions such as wiring, plumbing, heating ducts, etc. 

2.  Use a “stud finder” to locate positions of joists or rafters.  Make sure that your intended locations for your 

speakers is unobstructed and that the hole will be at least 1 inch away from joists or rafters. 

3.  Use the supplied compass or cut-out template/paint mask to draw a circle with the diameter that corresponds 

to the model of your speaker on the chart below, and carefully cut out the hole. 

4.  Remove the grille from the speaker assembly using the included grille remover tool. 

5.  Before installation, turn the “Angle Lug Installation Clamps” (Item A) so they are positioned as in image be-

low.  This way, they will clear the cut out hole for installation. 

6.  Prior to inserting the speaker assembly into the cut-out hole, attach speaker wires.  Make sure to observe po-

larity (the “+” and the “-”).  Speakers wired out of phase will exhibit an apparent loss of bass response.  The 

wires will be held in place by the “Spring Clip Terminals”  (Item B).  Wires should be stripped about 1/2

"

.   

7.  Insert the speaker assembly into the hole and begin to tighten installation screws.  As you start to turn each 

screw, the “Angle Lug Clamps” will rotate outward to engage ceiling material (Item C).  CAUTION:  DO NOT 

OVER-TIGHTEN THE CLAMPS.  Too much torque may snap off the lug, causing the speaker not to seat 

securely.  A snug fit is all that is necessary to assure proper performance. 

8.  If speaker assemblies are to be painted, either before or after installation, use the paint masking template 

(cardboard disc) to cover the speaker driver(s) to prevent damage.  DO NOT TRY TO PAINT THE GRILLE 

AND FRAME ASSEMBLY TOGETHER.  The grille should always be painted separately.  Use thin coats 

taking care not to block perforations with excessive paint. 

9.  If your speaker includes an “eyeball” type tweeter it may be aimed to achieve better imaging.  Tweeter output 

should be directed toward the typical listening position.  USE CARE TO AVOID DAMAGING THE DOME OF 

THE TWEETER DURING AIMING!!
