Introduction
Congratulations on your purchase of the Sonance
®
Architectural Series™ BPS-1 Bandpass Subwoofer
System. The BPS-1 system will add deep, powerful
bass impact to any audio system that includes
Sonance Architectural Series speakers. The BPS-1
cabinet remains completely hidden from view,
delivering its bass energy through a Sonance
Architectural Series Panel Bracket and Architectural
Finish Component that is a discreet complement to the
surrounding architectural space.
The complete BPS-1 Bandpass Subwoofer System is
comprised of a BPS-1 bandpass subwoofer cabinet,
an Adaptor Baffle, a dedicated Sonamp
®
A150 power amplifier, an Architectural Series Panel Bracket and
an Architectural Finish Component, all of which are available separately.
Design and Features
• Delivers powerful, room-filling bass through a small grille that complements the room’s architectural
design.
• Trimless and truly flush-mount installation — the plane of the subwoofer grille is perfectly aligned with
the plane of the ceiling.
• Available Adaptor Baffles allow the BPS-1 to be used with any size round or square Architectural Series
Panel Bracket (even 4”) to match other Architectural Series speakers in the audio system.
• The 8”
woofer driver features a felted paper cone with a rubber surround that should provide years of
reliable high-power operation. This allows the BPS-1 to be installed in a location that will have limited
or no access.
• The very efficient 4th-order bandpass enclosure produces high output over the subwoofer’s entire
frequency range.
• Adaptor Baffles are heavily flared to minimize port noise during high-volume passages.
• The BPS-1 can be used with any separately available Architectural Series Finish Component:
metal (with or without trim) or cloth (with or without trim).
• Sonamp A150 power amplifier (required, available separately) delivers 150 watts of power and
provides flexible connections that integrate the BPS-1 system into any audio system.
A built-in limiter
prevents overdriving the BPS-1’s woofer driver, even when using a single A150 to drive two BPS-1 subwoofer
cabinets.
• Front-panel amplifier controls (volume, crossover frequency, phase) let you fine-tune the woofer’s
performance to match a variety of listening environments and personal preferences.

Installing the BPS-1 Cabinet In New Construction
1. Determine the location for the
Architectural Series Panel
Bracket/Grille and install it
according to its instruction manual.
2. Determine the location for the
BPS-1 cabinet.
IMPORTANT: THE CENTER OF
PANEL BRACKET’S SPEAKER OPEN-
ING SHOULD BE APPROXIMATELY
12” FROM VENT TUBE END OF BPS-1
ENCLOSURE (SEE
FIGURE 2
).
MAINTAINING THE VENT TUBE’ S
PROPER LENGTH IS INTEGRAL TO THE
BPS-1’S ACOUSTIC PERFORMANCE.
LENGTHENING OR SHORTENING
THE VENT TUBE TO FIT A DIFFERENT
DISTANCE WILL ADVERSELY AFFECT THE BPS-1’S PERFORMANCE.
2. Attach the included Mounting Hole Drilling Template to the ceiling joist at the BPS-1 mounting location
(see
Figure 3
). Make sure that the template is placed high enough so the BPS-1 cabinet will not
contact the ceiling material after installation. (Contact can cause buzzing during operation.)
3. Drill eight
5
/
16" holes through the joist at the locations indicated on the Drilling Template (see
Figure 3)
.
4. Screw the two Temporary Installation Brackets across the underside of the joist bay at the locations
indicated on the Drilling Template (see
Figure 4
). The Temporary Brackets have two sets of pre-drilled
holes: One for 24” center-to-center joist spacing, and another for 16” center-to-center joist spacing.

5. Remove the Drilling Template from the joist.
6. Place the BPS-1 cabinet on the temporary brackets, aligning its mounting holes with the holes drilled
through the joist. (Insert shims underneath the cabinet as necessary to bring its mounting holes in
alignment with the holes
drilled in the joist.)
7. Screw the eight included lag
screws through the holes in
the joist and into the holes in
the side of the BPS-1 cabinet,
as shown in
Figure 5
. Use the
shorter lag screws for I-joist
construction; use the longer
lag screws for standard joist
construction.
8. After confirming that the
BPS-1 cabinet is securely
attached to the joist, remove
the temporary brackets from
the underside of the joists.
Selecting the Proper Adaptor Baffle
Sonance has BPS-1 Adaptor Baffles available that mate the BPS-1 to every size round and square
Architectural Series panel bracket. The Adaptor Baffles provide proper acoustic performance without
creating port noise or buzzing during operation.
Select the Adaptor Baffle that fits the particular size and shape Architectural Series Panel Bracket you
installed. BPC8R/S fit 8” Panel Brackets, BPC6R/S fit 6” Panel Brackets, BPS4R/S fit 4” Panel Brackets
(see
Figure 6
).
The Adaptor Baffles include Allen screws, an Allen wrench and Locktite.

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.
NOTE : MAKE SURE THE HOLES ARE HIGH ENOUGH ON THE JOIST SO THAT THE WOOFER CABINET WILL NOT
CONTACT THE CEILING MATERIAL. (CONTACT WITH THE CEILING MATERIAL CAN CAUSE BUZZING DURING
OPERATION.) THE ONLY CONTACT SHOULD BE BETWEEN THE CABINET’S GASKETED MOUNTING SURFACE AND
THE MOUNTING JOIST.
• Once the BPS-1 cabinet is attached to the joist, complete the installation by following the instructions in
the
Selecting The Proper Adaptor Baffle, Connecting The Vent Tube And Adaptor Baffle, Speaker
Connections
and
Installing The Architectural Finish Component
sections on pages 3 – 6.
