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

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.

WARNING

DO NOT ATTACH THE BPS-1 TO AN I-JOIST THAT HAS NOT BEEN ADEQUATELY BRACED. DOING SO CAN CAUSE COLLAPSE, RESULTING IN INJURY OR DEATH. CONSULT WITH THE JOB’S GENERAL CONTRACTOR BEFORE ATTACHING THE BPS-1 TO AN I-JOIST.

NOTE: DO NOT USE NAILS TO ATTACH THE TEMPORARY BRACKETS — THEY WILL BE REMOVED AFTER THE BPS-1 CABINET IS ATTACHED TO THE JOIST.

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.
