Installing the Woofer Cabinet: Retrofit
The BPS-1 can be retrofit installed into a ceiling that has an attic or adequate crawlspace above it.
Due to the variety of possible installation situations, it is not possible to recommend a single retrofit
installation procedure. However, in any retrofit situation you should observe the following points to
achieve a safe and noise-free installation:
•
Before installing the BPS-1 in any retrofit situation:
Review the section
Installing The BPS-1 Cabinet In
New Construction
on pages 2 – 3 to become familiar with the installation procedure for new
construction.
• Determine the location for the Architectural Series Panel Bracket and install it first (its location may
be influenced by the locations of other AS speakers in the room). Then establish the location for the
BPS-1 cabinet relative to the Panel Bracket. The vent end of the BPS-1 cabinet should be located 12"
from the center of the Panel Bracket's speaker opening (see
Figure 2
, on page 2).
• When temporarily placing the BPS-1 cabinet in the ceiling bay before attaching it to the joist, take
care to support it so that it does not break-through the ceiling material (The BPS-1 cabinet weighs 46
lbs.)
• Use the supplied drilling template to determine the locations of the mounting holes on the joist.
