Ceiling Subwoofer Model CSUB Installation and Use Manual © 2008 Bogen Communications, Inc. All rights reserved. Specifications subject to change without notice.
Product Description Thank you for choosing Bogen’s CSUB Ceiling Subwoofer. Please familiarize yourself with the product by reading and reviewing the descriptions and diagrams in this manual. Bogen’s CSUB delivers unsurpassed performance and value. This subwoofer can be installed either in suspended ceiling structures or hard surfaces (such as drywall). It is ready to install with swinging arm clamps that take the place of a tile bridge for installation in suspended ceilings.

Speaker Placement The low frequency capability of the CSUB allows great flexibility in its placement. While full-range speakers will typically be installed throughout the ceiling in an evenly spread pattern, the CSUB can be placed wherever it is most convenient. This usually means where the subwoofers best meet the needs of the overall sound system, or may sometimes mean where they best fit into the ceiling.
Installation The unique clamp-mounting system of the Bogen CSUB not only allows mounting in most types of ceiling surface thicknesses, it takes the ease of installation two significant steps further: 1. NO TILE BRIDGE IS REQUIRED. Because the mounting clamps are extra-long and very durable, they can suspend and support the CSUB across the 24" span of a suspended ceiling. This eliminates the need for the separate tile bridge required for nearly all ceiling speakers. 2.
Installation (cont.) SUSPENDED CEILINGS: 1. Remove the ceiling tile from the ceiling grid. Cut a 14-1/4" circular hole in the ceiling tile. Use the included template as a guide. 2. Put the CSUB face down on a workbench or on the floor without grille installed. 3. Place the ceiling tile over the CSUB, making sure the ceiling tile is facing out.
Installation (cont.) DRYWALL OR OTHER HARD SURFACES: 1 Be sure you know the location of the ceiling joists before cutting the speaker opening. Cut a 14-1/4" circular hole where the CSUB will be installed. Use the included template as a guide. 2. Make electrical connections to the snap-lock input connector and then plug it into the CSUB (see Speaker Wiring section). 3. Install terminal cover using the supplied screws. If using conduit, refer to the Terminal Cover section of this manual.
Speaker Wiring All wiring should be done prior to installation and then plugged into the rear of the speaker. Wiring is terminated at a snap-lock input connector. There are two positive and two negative terminals to accommodate daisy-chaining of speakers in a system. Daisy-Chaining The snap-lock input connector allows for easy daisy-chaining of speakers by providing a second terminal of each polarity. See the figures to the right and below for correct wiring for daisy-chaining of terminals.
Selecting Power Levels The front-mounted selector switch is used to set the appropriate power level or impedance for your system. Using your fingers or a flat-blade screwdriver, turn the knob until the arrow points to the power level you require. 70V Systems A power setting scale for 70V systems is labeled on the switch. Six settings are available, from 2 to 64 watts. 8-ohm Systems The fully counterclockwise position of the setting switch is the 8-ohm position.
