Step
Install the rear suspension point bracket to the back side of the
yoke using the supplied nut and bolt. Note that the bracket can
be installed in a variety of positions along the vertical axis of the
yoke. This permits the cabinet to be tilted as needed for precise
aiming.
SPEAKER STAND ADAPTER
A third mounting option permits the speaker to be installed onto
a standard tripod speaker stand or third-party mounting bracket
using the supplied stand adapter.
Step 1
Remove the mounting yoke from the loudspeaker by removing the
bolts on the top and bottom of the enclosure.
Step
Insert the stand adapter into the bottom of the enclosure and
secure with the bolt removed in step 1. Re-insert the bolt removed
from the top of the enclosure.
Step
Place the loudspeaker onto the stand and tighten the positioning
screw using the plastic handle. Hand tighten only.
CONNECTION & OPERATION
All models are fitted with NL4 style power input sockets for con-
nection to power amplifiers. NL4 connections are recommended
for all applications, whether permanent installation or portable
application. In addition all models except for the Forum 8M and
Forum 15M are fitted with barrier strips for direct termination of
wiring. On models equipped with both NL4 and barrier strip
connectors all connections are paralleled between the two
connector types.
Multiple speakers may be wired in parallel providing that the
resulting impedance is not below the minimum rated operating
impedance of the power amplifier. Refer to the amplifier installa-
tion manual for further details. Note that all Forum speaker models
are supplied in 8Ω configuration, except for the Forum 12Sub and
Forum 15Sub, which are also available in 4Ω versions.
The following table shows the net impedance when several 8Ω
speakers are combined in parallel.

NOTE: Never connect more than two 4Ω speakers in parallel on
one amplifier channel.
Always ensure that sound sources are set at the minimum level
before powering up the amplifier or powered speakers, for the
first time. Apply signal and increase the level slowly, verifying that
the signal is reaching the speakers and that the sound is clear and
free of distortion.
