Hold the speaker on the outer bezel edge as shown. Do Not put fingers into the tweeter material in
the center of the speaker.
WARNING! Denting or deforming the tweeter dome will change the acoustics of the speaker.
Insert the connected speaker into the ceiling hole and with a #2 Phillips screwdriver tighten the four
(4) Dog-leg screws (clockwise) until the Dog-legs open and clamp the speaker to the ceiling. If
using a power drill or electric screw gun use the
lowest
torque setting.
Over tightening may cause improper fit of the grille, damage to drywall, damage to speaker and or
cause improper fit of the grille.
Adjust the Tweeter position to your ear area at the “Sweet Spot” by slighting pushing on the inner
edge of the tweeter with your thumb.
NOTE:
If you have blown-in insulation and/or a potential rodent problem I suggest you install the SpeKap.
It is a breathable membrane that will keep rodent droppings, debris, and insulation from entering the back
of the speaker that could change the performance of the speaker. See figure on next page.
NOTE:
The R70VT transformer adapts any Current Audio 8 Ohm speaker for use with multi-speaker
70 Volt commercial distributed public address and sound systems. The CS65 and CECS series have
stand-offs for direct mounting the R70VT. It features a high power, low insertion loss, wide frequency
response quality line matching transformer design.
The transformer has multiple primary taps of 30-16-8-4 watts with the secondary at 8 Ohms. See figure on
next page.
