Found on one site:
"Leave the psychoacoustics to Dr Armar Bose. He's been fooling the public for many years and I'd hate to take that crown away from him!"

27. Why doesn't Bose publish full system specifications for L1 systems?

A. While some specifications add value when comparing two otherwise similar products, they're mostly meaningless for a product as fundamentally different as the Cylindrical Radiator® loudspeaker and the L1 system. In addition, most specifications used to describe sound systems can be very misleading. They suggest relatively complex physical or perceptual properties can be condensed to a single or small set of numbers that defines overall quality or performance. In many cases these numbers only loosely relate to what you would experience in a real-world application.

There are also several variations in how a specific measurement can be carried out, making number comparisons useless. We believe it serves our customers better to describe L1 systems in terms they can relate to more directly. We also encourage customers to experience an L1 system personally, either at a demonstration or in actual real-world trials they conduct themselves.


YEAH, RIGHT...
DO NOT LOOK BEHIND THE CURTAIN!
WE ARE THE GREAT AND POWERFUL BOSE...
