Hey guys! I'm working on a project for school using the instructions found at http://www.josepino.com/other_projects/index.php?homemade-hifi-speaker.jpc . I made two of the speakers, one with a foam plate and one with a paper. Now, after testing, I found that the foam plate DOES work better than the paper one. My question is WHY. I'm thinking that it's either lighter and moves easier, or something about deflecting sound. I can't find any information online, so I'm asking here.
Thanks. :]
You are correct the lighter the material used the easier and less power it will take to move...... sound is really nothing but waves of air....at different speeds and our ears pick up it gets complected to explain after this
many reasons many manufacturers in high end use anything built paper cones is efficiency's..and clarity...no flexing of paper vs whatever material they may choose......paper cones are much more dense and can take more power to move...but there are advantages to them depending on uses
