Three Position Treble Adjustment
The High adjustment slide switch on the front of the speaker allows you to adjust the
tweeter level - 3 dB or +3 dB from its 0 dB middle position. If you are mounting the
speaker in a “live” room with many reflective surfaces, you may want to attenuate its
treble response. Conversely, if you are mounting the speaker in a “dead” room with many
absorbent surfaces, you may want to boost its treble response.
Installing Precision Architectural Loudspeakers
1. Confirm that there is at least 1 1/2" of clearance between each edge of the planned
cutout and adjacent studs or joints.
2. Fasten the supplied cardboard template to the wall or ceiling with tape or thumbtacks.
Check again for equal distance of both speakers from the wall.
3. Trace around the perimeter of the template.
4. Before making the final cutout, make a small “test cutout” in the center of the penciled
outline. Reach inside the test hole to verify that there are no obstructions in the way of
your planned cutout.
5. Before cutting the hole, first score the drywall with a razor knife and use a keyhole
saw to complete the cut. Remove debris from the edge of the hole.
7. Secure the speaker wire to a stud near the cutout so its weight will not tug on the
terminals of the speaker after it is connected. This also keeps the wire from dropping
behind the wall before you can connect it.
8. Push down the tab on the speaker terminals and insert the speaker wire into the
connector.
9. Insert the speaker into the cutout to make sure it fits easily without forcing.
10. Evenly tighten the mounting screws on the bezel. The mounting “swing-arms” will
automatically swing out 90 degrees. After they swing out, the arms then clamp against
the drywall from behind the wall. Avoid using excessive force to prevent deforming
the drywall or cracking the speaker’s mounting frame.
11. We recommend that you add a “blanket” of sound absorbing material such as ceiling
insulation behind the woofer to reduce sound transmission into the adjoining room.
Additionally, any sound leakage from behind the molded frame can be blocked with
foam weather-stripping directly behind the plastic speaker bezel.
