Precision Econowind, Inc. is a privately owned American company that manufactures custom coils for the loudspeaker, medical, aerospace, and many other industries.  Loyal Tingley, Jr. and his son Terry started the business from a one-car garage in Bokeelia, Florida in 1972. Today Precision Econowind, Inc. is owned and operated by Terry Tingley and Dean Wiant. Precision has become one of the world's premier custom coil manufacturer that supplies many of the largest companies around the world in many different industires.

At Precision our goal is to consistently provide the highest possible quality, at a competitive price, with on-time delivery. Our specialty has been voice coils for the loudspeaker industry, and we are very proud that our coils are used in speakers made by companies worldwide. Since then times have changed as we have branched out in to other industries from our core business of voice coils for loudspeakers to high quality custom voice coils for medical, OEM, Aerospace and just about any other industry that uses custom voice coils in their products. Specializing in voice coils has given us experience in winding precision layered coils using bondable wire. This skill is the foundation for many of our other custom coils, especially freestanding coils that require the most efficient possible use of space, which can best be accomplished using precision layered winding with no bobbin or core.

We occupy 32,000 square feet of manufacturing space in Southwest Florida. Our winding machines and tooling are custom designed by us and built by our own machine shop specialists. For coils requiring high temperature resistance we coat our own wire and form material with high temperature adhesives.
