Building a Speaker....New member ok, well firstly let me introduce myself; I am a new member here, I am by no means a physics/engineering person...but I got myself stuck in grade 12 physics and I am almost through the semester. Now we've got this assignment to build a speaker or headphones from scratch. Me and my partner spent the last 5 hours trying different things and researching all over the net with no success. Anyone got some clear(fool proof) ideas?? Thanks Zack.
