Dear Mr. Griffin-
Thank you for your interest in Bose Corporation.
We appreciate the difficulty that consumers face when choosing loudspeakers. Information provided by manufacturers can often be confusing, and it may suggest a basis for comparing speaker performance that is unrelated to the speakers' performance in your listening environment. Furthermore, a speaker's response in a lab (or even a calibrated living room) does not always suggest that you will achieve that response in your room.
There is a great deal of variety in response-measuring techniques. Most of these techniques neglect how a listening room and the speakers' placement in that room can affect the response. On top of that, there is no clear and easy methodology for comparing responses. Our feeling is that response curves are a poor customer tool for comparing two speakers. For this reason, Bose (R) elects not to publish curves.
Bose recognizes that listening to a speaker in an audio store can only approximate the performance that a customer might achieve at home. Only when a speaker is installed in a listening room can the customer learn what its actual performance is. That's why Bose designs speakers using a combination of laboratory measurements and real-world evaluation methods in homes that represent a broad range of sizes, shapes, and constructions. We want to ensure that our speakers sound good in the listening environment that really matters; yours.
Taking a car for a test-drive cannot tell you what it will be like to live with that car. Similarly, a brief audition of a speaker can only begin to tell you what you might experience in your home. The common thread is that you are the customer, and you are the one seeking an enjoyable experience. You can compare speaker specifications and read reviews, but this will not tell you what you will experience in your own home. You can ask your friends what they like, or read testimonials from Bose customers to learn about their experiences and this may suggest that your experience might be similar.
Ultimately, your ears are the only equipment that can adequately compare speakers for you. We can only do the best we know how, using proven research and decades of design experience. We are confident that our speakers' performance compares favorably with the many high-quality speaker products available today. Our customers have consistently expressed their satisfaction with, and enjoyment of, Bose speakers and systems over the years. We hope that you will have an opportunity to reach the same conclusion.
Please let us know if there is anything else you need.
Thank you for contacting Bose Corporation.
