Setting Up

Before you begin
Thank you for choosing Bose 141 series II bookshelf speakers. Their quality construction is meant to provide high-quality listening enjoyment in your home. The 4.5-inch full-range driver inside each speaker delivers performance usually associated with much larger, more costly speakers. Please read this owners guide. It will help you set up and use the speakers properly, so they can deliver the finest sound for your listening pleasure. Note: These speakers are not designed for use outdoors or in automobiles.
CAUTION: To avoid danger of suffocation, keep the plastic bags that wrap these speakers out of the reach of children.

Unpack the carton

Carefully unpack the carton. Save all packing materials for possible future use. Carefully peel the clear protective plastic strip from each speakers metallic accent panel. Inspect the speakers. If either speaker appears damaged, do not use them. Instead, repack both speakers in the original carton and notify your authorized Bose dealer immediately. Note: Now is a good time to record your speakers serial numbers. Write them in at the b eginning of this guide and on your warranty card.

Rubber feet

Select locations for your 141 series II bookshelf speakers
Your 141 series II bookshelf speakers are designed to provide full stereo performance while taking up very little space. You can easily fit them on a shelf or table, either horizontally or standing on end. For best performance: Place the speakers at least 5 feet (1.5 m) apart. Position them within 18 inches (45 cm) of the wall behind them. Avoid placing them exactly halfway between the floor and ceiling. To prevent video interference, keep them at least 2 feet (61 cm) from any video screen. CAUTION: 141 speakers are designed specifically for placement on a stationary shelf, table, or stand. On smooth surfaces like marble, glass or highly polished wood, vibrations may cause the speakers to slide. So be sure to attach the self-adhesive rubber feet to the bottom surface of each speaker for added stability and protection.

Connect the speakers

Position the opening on the front of each speaker (its port) toward the side wall of your room. Or set speakers port side down if you position them vertically. As you face the speakers, the speaker placed on your right will connect to the RIGHT SPEAKER channel of your amplifier or receiver.

Choose the cord

It is important to use the proper gauge (thickness) of speaker cord. Standard zip cord (2-conductor, 18-gauge stranded wire) works for most applications. You can find this wire at most electrical and hardware stores. You will need thicker wire if your speakers will be more than 30 feet from a receiver or amplifier. Refer to the wire recommendations under Technical information on page 7, or contact Bose service or your local Bose Service agency for more information. Note: Before running speaker cord through a wall or under a floor, check your local building code requirements and safety regulations. You may want to contact an electrical installer for this information.

Caution: Before making any connections, turn off your receiver or amplifier and unplug it from the outlet (AC power mains). Not doing so may result in damage to your system.

Prepare the cord

Speaker cord consists of two insulated wires. The insulation around one wire is marked (striped, collared, or ribbed). This marked wire is always positive (+). The plain wire is always negative (). These wires correspond to the red (+) and black () terminals on the speakers and the receiver or amplifier. At the ends of each cord, strip approximately 12-inch (12 mm) of insulation from both wires. Twist the bare end of each wire, so loose strands will not touch across terminals. Be sure to connect each wire to the proper terminal (positive to positive and negative to negative). Note: It is sometimes difficult to distinguish wire markings. Inspect both wires carefully.
Caution: Never use broken or frayed wires, which can result in electrical shock or damage.

Make the connections

Just press down the terminal tab on the back of each speaker to insert the appropriate wire (Figure 2). 1. Connect one speaker cord to your right speaker. a.Attach the marked wire to the red (+) terminal. b.Attach the plain wire to the black () terminal. 2. Connect the other end of the same cord to the RIGHT SPEAKER OUTPUT of your receiver or amplifier. a. Attach the marked wire to the red (+) terminal. b.Attach the plain wire to the black () terminal. 3. Connect the second cord to the left speaker and LEFT SPEAKER OUTPUT. Follow the procedure described above.

Setting Up Check the connections English
Check to be sure all connections are made positive to positive (+ to +) and negative to negative ( to ). Make sure that no loose strands of wire touch across terminals. Loose wire strands could short circuit, which can result in electrical shock or damage. Tighten any loose connections before you plug in the receiver or amplifier and turn it on.

Test the speakers
To make sure your speakers operate correctly:
1. Set your receiver or amplifier to MONO (monophonic) and turn it on. 2. Set the balance control to normal (center position). 3. Place the speakers less than 6 inches (15 cm) apart, facing each other. 4. Play some deep bass passages of music through the speaker. The sound should seem to come from a point between the two speakers. The bass should be full and natural. If it is not, your connections may be out of phase. To make them match connections to the amplifier, try reversing the + and connections on the back of one speaker. Then repeat steps 1 4.
Maintaining Your Speakers

To clean your 141 series II bookshelf speakers
Wipe the Model 141 speaker cabinets clean using a soft cloth dampened with a mild detergent. Do not allow liquids to spill into the speaker grilles. No other regular maintenance is required.
