What is Mylar?
Mylar is a common name of cone material that is widely used in small to middle size loudspeakers. Mylar is also known as polyethylene terephthalate, or PET, which is used in a water or soda bottle. A major advantage of mylar over untreated paper as a cone material comes in applications where moisture or humidity are considerations. While untreated paper tends to absorb moisture – affecting the mass of the cone, with a resulting shift in resonance – mylar is relatively immune to this. It is also easily and consistently moldable, making it a cost-effective solution in these applications.
