I want to learn how to build a speaker...mostly out of interest. The thing that i always wonder is people talk about speakers like "it hits those high's very well but can go deep very full sounding" and stuff like that when all i hear from people who build speakers is making a box and putting the drivers in. Im interested to know what makes a speaker sound the way it does, is it how big the drivers are and the shape of the box or is it little articulations in the drivers the developers built. Aslo, impedence, power handling, sensitivity..i know what those are but how do you get them there? Examples: What in a speaker makes it 8 ohms and why are some speakers 8 ohms instead of lower ohms so they can get more power? power handling, how do they even come up with that number and how would a person come up with that number if they were building a speaker? Sensitivity, what makes sensitivity...sensitivity i guess. I recently took a part a bookshelf i had to look at it, basically the the sub had 2 black and 2 red wires goin into it, 1 red and 1 black went to the tweeter and 1 red and 1 black went to the positive negative thing on the back. What in the a driver makes the sound i was lookin at it and i saw a copper coil in there, a magnet and the rest i couldnt describe and the tweeter looked skinny. Im really interested in the sound question cause i dont want someone to say "this thing here, thats what makes the sound" or something liek that i want to know how indetail i wanna know how speakers work. I was hoping for people to post sites of some sort, maybe that could help me out, what i would really love to see is pictures of speakers that somebody built themselves and stuff or sites on there speakers. Thanks, im a pain in the neck.
