• The correct four remaining tether bolts for the upper two modules as deter-
mined by the table in Section 8.
• Four expansion spike sub-assem-
blies.
Mounting Procedure
Note: The module’s center of gravity will be
somewhat forward and unbalanced until the
tether bolts are secured. Have an assistant
stabilize them while you install rear spikes
and heads.
The front-to-back location of each mod-
ule, along with the use of the proper length of
rear spike of the upper modules, achieves the
correct propagation delay and axial response
vis-à-vis the listener.
Install the front pair of short (A length)
spikes into the bottom of each module (see Fig-
ure 15).
Install the Lower Midrange Module (LMRM)
The lower midrange module (LMRM) is in-
stalled first. Install the module as follows:
• With the front spikes pointing
down, carefully lower the LMRM
between the alignment wings and
set it on top of the woofer en-
closure (see Figure 16). Ensure
that the tether bolts are protrud-
