Sonance Architectural Series
BPS -1 IN-CEILING SUBWOOFER
I N S T A L L A T I O N M A N U A L
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, a
Bandpass Connector, a dedicated Sonamp
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 Bandpass Connectors 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. Bandpass Connectors are heavily flared to minimize port noise during high-volume passages.
• The 8"
woofer driver features a felted paper cone with a rubber surround and Kapton
that
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.
• 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.
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.

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.
- Page 3 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.

Pass the speaker wire through the BPS-1’s built-in wire tie, and route the wire’s end to the speaker connector panel (see Figure 12). - Page 6 “–” to speaker “–”. 5. Once you have verified that the connections are correct, tighten the wire tie to secure the speaker cable to the BPS-1 cabinet. This will help prevent the speaker from being accidentally disconnected in the future.

Page 7: Specifications
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. - Page 8 Sonance will (a) at its option and expense during the warranty period, either repair the defect or replace the Product with a new or remanufactured Product or a reasonable equivalent, and (b) arrange at its reasonable expense to re-install the Product and prepare the surface of the speaker and/or mounting platform for finishing and nothing more.
