Using Your 901® Series VI Speaker System

Adjusting the sound

Adjust the sound using the MID-TREBLE and MID-BASS sliders and BASS control on the 901® active equalizer. Use the tone controls on your receiver only after the MID-TREBLE and MID-BASS sliders have been set according to the procedures below.

Using the MID-TREBLE and MID-BASS sliders

These controls let you make adjustments to compensate for the effects of speaker location, room acoustics, and program quality.

1.Select a familiar musical piece.

2.Set your receiver tone controls to the center (flat) position. If it has a loudness compensa- tion control (marked LOUD or LOUDNESS), set it to the OFF or OUT position.

3.Set the MID-TREBLE slider on the equalizer to its center position.

4.Play the selected music through the 901 speakers at normal volume. Move the MID-BASS slider back and forth several times and listen to the effect. You should hear a significant change in the fullness of the sound. If you do not, the active equalizer may not be en- gaged. Refer to Playing your speakers on page 14.

5.When you are familiar with the effect of the MID-BASS slider, set it to the extreme left. Start the musical passage again and slowly advance the MID-BASS slider to the right until the sound is rich and full, without excessive heaviness.

6.Replay the musical passage, this time moving the MID-TREBLE slider back and forth to become familiar with its effect. You should hear a significant change in clarity of the sound.

7.Set the MID-TREBLE slider to the extreme left and play the passage again. Slowly advance the MID-TREBLE slider to the right until the sound is clear and detailed without excessive shrillness.

Using the BASS control

The Bass control provides an alternate bass equalization. It is not a bass enhancement switch, and it is not intended to boost the bass output of the speakers.

Press the BASS control IN (to position 2) to engage an alternate form of equalization that changes the way the speakers handle low-frequency information. For example, you may prefer pipe organ music with the alternate equalization. The control can also be useful in eliminating feedback or rumble from a turntable.

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.
