Bose 901 frequency response
Maybe this will answer some of your question, this was from another inquiry about the same subject from another forum and this is the response the individual received from Bose (if not you can always contact Bose and inquire specifically about frequency response)...............
Thank you for your inquiry. Bose (R) Corporation does not publish frequency responses, simply because they are not accurate and usually will mislead the customer.
Frequency responses are usually measured with testing equipment set up in an anechoic chamber. An anechoic chamber is an isolated room designed so that sound will not reflect off any surfaces. Giving out such frequency response results is terrific- for those people who live in anechoic chambers! Most of us listen to our systems in rooms with very reflective surfaces, such as plaster, brick, glass, and dry wall, so the frequency response that a manufacturer may supply is no longer accurate. Just as no two rooms have the same dimensions, nor are they decorated exactly the same or have the same construction, no two rooms will sound the same when using the exact same
speakers and amplifier.
For example, if you were to place any speaker in a room with no carpeting and wooden furniture, you would hear something completely different than if they were placed in a room with shag carpeting and plush furniture. Perhaps
this can be equated by imagining a single lighted candle placed in a room with completely black floors, walls and ceiling. Obviously, the same candle when placed in a room with white surroundings will appear to be emitting
much more light than when placed in the first room with black surroundings, as the light will reflect a great deal more off the white surfaces. Sound reflects off surfaces, much like light does. The surroundings make the speakers sound different in the same manner, because they actually are able to reproduce different frequencies via sound reflection and speaker placement.
We hope you do not take the fact that we do not publish speaker frequency responses personally. We do not publish our speakers specifications to anybody, whether it be before or after they have purchased a speaker system
of ours. We simply invite our customers to listen to our speakers using the most accurate testing equipment possible- their ears.
