[QUOTE="Joseph7195, post: 8481112, member: 633259"] I am about to build up some old Fosgate motors, and it had me wondering. How can I make the most informed decisions on the components to build my subwoofers? How does cone weight affect the sub? Does magnetic gap and voice coil length change characteristics of the sub substantially? What affects do the materials and stiffness have on the spiders? What I would really like is someone to explain to everyone, how changes to a subwoofers many components, can change its characteristics, and how someone could use this knowledge to build a subwoofer to fulfill all of one's needs. I know all the Thiele-Small parameters, and their meanings, but how can they be changed to benefit us in the real world. Maybe someone could tag some builders like Jacob at sundown, Dave flstrongman, or Spl Cory. [/QUOTE]
