Invisa® Series Owner’s Manual
5. For In-Wall Mounting:
• For optimum performance, loosely place two pieces of standard fiberglass insulation in the wall,
one just above the hole and one just below. An 8" x 10" piece should work well, R-12 for a 2x4 wall,
R-20 for a 2x6 wall.
• Also place a half-thick piece of fiberglass insulation cut to the height of the speaker in the wall right
behind the mounting hole.
6. For In-Ceiling Mounting:
• For optimum performance, loosely place one piece of standard fiberglass insulation, cut to fit the
joist size, above the speaker and extending about 15" or more beyond the speaker;
• For taller joists, also place fiberglass insulation against the joists on either side of the mounting hole.
7. Pull the speaker wire out of the hole and connect the speaker as follows:
• Your Invisa ® speakers are equipped with a set of high-quality push spring connectors that can be
used with bare wire. Make sure all wires are firmly fastened. Always use high quality speaker wire
of the correct rating (see above) and sufficient gauge for the distances you are running (see your
dealer for assistance).
• Strip 1 /
2
" (12 mm) of insulation from each of the two conductors to expose the metal, twist the
strands of each into a single un-frayed strand.
• Hold the speaker up to the cutout and connect the speaker cable. Proper polarity (or phase)
is critical for proper stereo imaging and bass performance. Connect the red(+) terminal of your
receiver or amplifier to the red(+) terminal of the Invisa loudspeaker and the black(-) terminal
of your receiver or amplifier to the black(-) terminal of the Invisa
loudspeaker (See Figure 3). Most speaker cables are either color
coded or have some indicator (ribbing or writing) on one of
the conductors to help maintain this consistent polarity. It is
essential that all speakers be connected in the same way
(in phase) to its own channel of the amplifier. If you experi-
ence a great lack of bass, it is
likely that one speaker is out of
phase(+ and – reversed) with
the other.
• Push down on the top of the speaker’s push terminal to reveal
the wire hole in the post. Insert the wire into the hole and release
your pressure on the terminal.

Turn your amplifier/receiver OFF before performing any connection steps, in order to prevent
accidental damage to your amplifier.
If you plan to use multiple speakers per amplifier channel. The minimum impedance of ONE Invisa
in-wall/in-ceiling speaker is 4 ohms per channel.
