Bose 901 Speaker Placement Guide: Ceiling and Wall Mount Options

Setting Up

Choosing the location for your speakers

Choose locations for your 901® speakers that use the walls to best advantage by reflecting sound throughout the listening room. Refer to the drawing on page 7.

Guidelines for placement

Place the speakers along the same wall (see Figure 3):

•4 to 12 feet (1.2 – 3.6 m) apart, with the V-shaped rear of the speaker between 8 and 18 inches (20 – 45 cm) from the rear wall. Do not aim the V toward a corner.

•18 inches (45 cm) of clear space around the sides, top, and bottom of the speakers.

•at least 2 feet (60 cm) from sound-absorbent furnishings.

•18 to 48 inches (45 – 120 cm) from the side and rear walls.

•18 to 36 inches (45 – 91 cm) from the floor or ceiling. Do not place the speakers exactly halfway between floor and ceiling.

Within these guidelines, remember that the closer the speakers are placed to a reflective surface, like a wall, the more bass is reproduced.

Choose the support for your speakers

You may place 901 speakers on a table or shelf. You may also use Bose® floor pedestals, or suspend the speakers from your ceiling. Refer to Figure 3 on page 7.

To set the speakers on a table or shelf

Although each speaker weighs 35 lb (16 kg), a suitable shelf or table must be able to support 140 lb (64 kg). Keep an adequate distance between the speakers and the rear wall as listed in “Guidelines for placement” above.

To stand the speakers on the floor

Use only Bose pedestals (PS-6) as floor stands. They are designed to provide the proper support and are available through your authorized Bose dealer. Please read the pedestal attachment instructions before making any speaker connections. Four pilot holes on the bottom of each speaker (see Figure 2, hole set A) are pre-drilled for the purpose of anchor- ing the speaker to the pedestal.

To suspend the speakers from the ceiling

Use these guidelines to ensure safe suspension of your 901 speakers. Three steel support chains are recommended. We cannot specify the ceiling attachments. The type to use depends on the type of building construction.

CAUTION: Do not mount on surfaces that are not sturdy enough, or that have hazards concealed behind them, such as plumbing or electrical wire. If you are unsure of your ability to install these speakers, contact a qualified professional installer.

Note: The speakers hang in an inverted position, with the terminal connections facing up. Carefully rotate the Bose logo 180˚ (so it appears right side up) before hanging the speak- ers.

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.
