Setting Up

Speaker connections

With your speakers in their chosen locations, connect them to the receiver.

Choosing the wire

It is important to use the right thickness of speaker wire. For distances of up to 30 feet (9 m), 18 gauge (.075 mm2) 2-conductor wire works well. For distances greater than 30 feet (9 m), refer to the wire recommendations chart on page 18.

Note: To determine if this wire is suitable for use in a wall or under a floor, check your local building codes. You may want to contact a qualified electrical installer for this information.

Preparing the speaker wires

Examine the speaker wire. Note that it is actually a pair of insulated wires that may be gently pulled apart. The insulation around one wire is marked with a stripe, collar, rib, groove, or printing. Use the marked wire as positive (+) and the unmarked wire as negative (-). These wires correspond to the positive and negative terminals on the speaker and receiver.

Note: It may be difficult to distinguish wire markings. Inspect both wires carefully.

To prepare the ends of each wire:

1.Strip approximately 1/2 inch (12 mm) of insulation from both wires.

2.Twist the bare ends of each stranded wire, to prevent strands from touching across terminals.

Connecting the speakers

CAUTION: Before making any connections, turn off your receiver and unplug it from the

AC (mains) power outlet. Not doing this may result in damage to your system.

Speaker terminals are located on the bottom of each speaker. Unscrew the knurled nut on each terminal and remove one washer. Wrap one bare wire end around the terminal post. Then, replace the metal washer on the screw post and screw the knurled nut firmly back on.

1.Connect one wire pair to the right speaker (the one on your right as you face it).

a.Attach the marked wire at one end to the positive (+) terminal.

b.Attach the plain wire at that end to the negative (-) terminal.

2.Connect the other ends of the same wire pair to the RIGHT SPEAKER OUTPUT of your receiver.

a.Attach the marked wire to the positive (+) terminal.

b.Attach the plain wire to the negative (-) terminal.

3.Following the steps above, connect the second pair of wires to the left speaker and to the LEFT SPEAKER OUTPUT on the receiver.

Note: If your receiver offers a choice of output impedances, use the terminal marked 8Ω or 8 ohms.

901 specifications

The Bose 901 speaker system, first introduced in 1968, has become an iconic piece of audio equipment renowned for its unique design and innovative sound technology. Renowned for its ability to deliver an immersive listening experience, the Bose 901 stands out in the world of high-fidelity audio.

One of the most notable features of the Bose 901 is its Direct/Reflecting speaker technology. This system utilizes nine drivers per speaker, of which eight are angled to reflect sound off walls and other surfaces in the listening environment. This design allows the speakers to create a more natural and spacious soundstage, replicating the listening experience found in live performances. The additional driver faces forward to provide direct sound, ensuring that both reflected and direct sound are delivered in harmony.

The Bose 901 is also equipped with an equalization system that enhances its performance. Each speaker comes with an equalizer specifically designed to tailor the sound output to achieve the best possible audio quality. This equalizer compensates for the natural deficiencies in speaker performance at various frequencies, resulting in a well-balanced sound profile. The equalizer can be adjusted to accommodate different listening environments, allowing users to optimize sound output based on room size and shape.

Another defining characteristic of the Bose 901 is its sleek design. The speakers feature a low-profile cabinet that fits seamlessly into various home decors. The compact yet robust construction allows for various placement options, whether mounted on stands or against a wall. This versatility ensures that users can easily incorporate the speakers into their living spaces without compromising on aesthetic or audio performance.

Durability and build quality are also significant aspects of the Bose 901 design. Historically, the materials used in construction have ensured longevity, contributing to the speaker's reputation for reliability. The fabric grille protects the drivers from damage while contributing to the clean, unobtrusive appearance.

In summary, the Bose 901 is a speaker system that marries innovative technology with thoughtful design. With its Direct/Reflecting speaker technology, unique equalization system, and elegant aesthetics, the Bose 901 has cemented its status as a revered choice for audiophiles seeking an exceptional listening experience. Whether enjoyed in a dedicated home theater or as part of an everyday audio setup, the Bose 901 continues to deliver sound that resonates with music lovers around the world.
