The modern stereo system

Modern stereo systems have moved far beyond the original goal of the accurate reproduction of sound. Many years ago I taught a section on audio in my high school electronics classes. One part of the curriculum covered the range of human hearing and how different audio components covered each portion of it. I’d recommend anyone wanting to put a comprehensive sound system in their car to do some research on the frequency range of various audio devices. Speakers, cross-over circuits, filters and enclosures are all part of any comprehensive audio system. At one time high-end audio installers would do an acoustic analysis of homes and cars using pink noise. I think you would find the research into all this quite enlightening. It would also help you understand proper placement of the various elements of an accurate sound system. Tweeters, for instance, are highly directional and work best at ear level, which is why you see so many of them mounted on windshield pillars or on stands in a home environment. You might do some reading on why most professional musicians prefer tube amplifiers and avoid non-analog devices. In my opinion, modern audio systems, whether in homes, cars, boats, etc., have succumbed to a fad of exaggerated bass at the expense of everything else. It’s a reflection of modern musical tastes, but it doesn’t mean they provide good, or accurate sound. Just my opinion. My hearing these days pretty much signs off above 4kHz, but I still enjoy hearing good music, even if I can’t hear all of it. If you are young, think about that. Loud things can be fun, but come with a price if you don’t protect your hearing.
