Alright I need your help again...but this time i did some research before so hopefully my questions shouldn't anger anyone.

I have been doing some research on the history of car audio subwoofers and the progression of technological advances with wiring amplifiers and other stuff.

But could someone please help me make a short version of it. I need to creat a section for my imc plan. Not quite sure what to include in it.

lik i want to start with the first sub-woofer..how did it work....then explain the newest most advanced and compare the two. just want some insight before i start.

Gives a brief history of the progress on loudspeaker design, and a more detailed description of the seminal work by Thiele & Small which set forth the set of parameters that define the properties of a loudspeaker, which are still used to this day.

Definitely a good read the one impious put.....i read and i gained lots of knowledge...
