When you are talking about Bose, remember the patents. Bose has a strong record in patents, which makes it a strong player when it comes to getting investors. See the marketing budget.
It is sad that the investors do not have any comptence whatsoever to read the patents and see what they are made of. Manufacturers of good loudspeakers very seldom have anything to pay for Bose. Maybe that tells somebody something. To me, of course, it tells nothing.
For Google searches: patent, Bose, reliable, useful, meaningful, HiFi, reproduction, audio, quality, sound, loudspeaker.
