Harman International is one of the few companies who puts out loads of white papers, research papers and info on their products and works to disseminate their ideas on audio and acoustics to the public. I like that they do that. It means we get more info and can be more informed about what to look for in selecting an audio product – whether it’s one of their products or anyone elses.
For example, they have a video here showing how they test iPod docks and are able to compare several different units quickly and easily and with proper scientific rigor. They’re also able to test larger speakers and other products using this system. For stereo setups I think they have a larger room that can move pairs of speakers around. I’d love to check out their system in person sometime and see how my ears compare against their trained testers.
