i guess that some people don't understand why many of the technical technicalities can be very important to some other people.
not everyone only uses or needs good speakers at home to listen to music, or use a home theater/entertainment suite.
some people work with music, either in sound engineering, production, or are themselves musicians.
in which case they need speakers which are suited to them, and need to know WHY those particular speakers are suited to them, so they can recreate this wherever they are (obviously within the context of the average spaces they intend to do it in, even if they intend to use hired gear, it is wise to have even a basic understanding of all of this).
some musicians for example play acoustic instruments, and when they need amplified for some spaces, then generally certain set ups work much better for them.
other musicians may work purely electronically/digitally (like a techno music musician) so certain other set ups may suite them.
and you will find this will be similar for their home,perhaps, in that their domestic set up may reflect their work. although some of us like to leave work at work!
other folk need audio gear for research purposes and may be buying it on behalf of their university department so certain criteria may need to be fulfilled in various qualities.
i was quite impressed by how much detail the written stuff linked to from this page was, despite much of the language as yet being a bit over my head. but liked how it gave me a load of terms to look up and become familiar with.
although the algebra took a few reads through to grasp, it actually was not too difficult and was on a level with secondary education (middle school in U.S.?) and online calculators can help, or any basic calculator that has "scientific" settings on it.
my main interest at the moment is in deciding shapes and proportions with which to build cabinets for a slightly large sound system for mainly outdoor use, so i will need a little maths to work out the best proportions to get the best out of the materials used.
then that whole minefield of resistance, amps, etc etc etc, to get it all clean and efficient (with all of those taken into account and sorted, then even a 1500watt setup can rip the back-side off a much larger setup up, and save money, and weight.)
i think i will enjoy being a member of this forum!
