The introduction of the revolutionary Bose® 901® speakers in 1968 redefined the phrase high fidelity. For the first time, a speaker was capable of reproducing music with much of the impact, clarity and spaciousness of a live performance. Today's 901 speakers incorporate some 350 enhancements over the acclaimed original. 901 speakers work by reflecting most of the sound off walls and other flat surfaces, instead of aiming all the sound toward you, as conventional speakers do. With Direct/Reflecting® speaker technology, anything you listen to, from the latest DVD audio to your favorite vintage records, acquires lifelike realism, because the speakers reproduce the natural concert hall balance of direct and reflected sound. The result is what we call Stereo Everywhere® speaker performance, stereo performance that is clear and lifelike everywhere in the room, instead of in just one "sweet spot." You'll experience balanced sound throughout the listening environment, no matter where you sit or stand. Just as you enjoy beautiful music reproduction from these speakers, you can also experience thrilling home theater effects from your home theater components. These speakers are an appropriate choice for use with your surround sound receiver, and can be used in conjunction with other Bose home theater speaker options.
