Using Your 901® Series VI Speaker System

Equalizer compatibility

The Bose® 901® Series VI active equalizer is designed for specific use with

Bose 901 Series VI speakers. It may also be used with 901 Series V speakers.

WARNING: Bose 901 Series I, II, III, or IV speakers require a substantially different equalization. The 901 Series VI active equalizer must not be used with Series I – IV speakers. For additional information on the active equalizer, please contact Bose Service.

Connecting additional speakers

The type of speakers and how you will use them determines how many amplifiers and 901 active equalizers you will need.

To run other non-901 speakers simultaneously requires the addition of a second amplifier. To use other speakers simultaneously with the 901 speakers requires the ability to isolate the 901 active equalizer signal so that it affects only the 901 speakers.

Adding 901 speakers

You need just one 901 Series VI active equalizer to use a second pair of 901 Series VI speakers connected to a single receiver or amplifier. Connect the additional speakers to the additional speaker output jacks on the receiver or amplifier.

To use extra 901 speakers in a four channel or time-delay music system, you will need a separate 901 active equalizer for each pair of speakers.

Adding conventional speakers

You need a separate power amplifier to play conventional speakers at the same time as 901 speakers. Connect the 901 active equalizer to the amplifier that drives the 901 speakers only.

CAUTION: Make sure the conventional speakers do not receive signals from the 901 active equalizer.

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.
