Custom Voice Coils

Custom voice coils have been the core of our business at Precision Econowind since we began producing electric coils over 40 years ago. Round, rectangular, D-shaped, flat wire or custom shaped coils can be produced using precision layering practices. Single layer, multilayer, wet wound, dry wound, bifilar, multi-filar, dual, and quad coil configurations are available. Custom manufacturing solutions can be designed for a range of sizes and coil configurations. Copper, aluminum or CCA wire from #16 AWG to #48 AWG can be used to create voice coils with inner diameters ranging from 0.232”-10.0”. Custom inner diameters can be fabricated with custom tooling if required. Tolerances as tight as ±0.001” can be held on inner diameter dimensions.

Coils are wound using our proprietary high-temperature adhesive capable of withstanding operating temperatures upwards of 500°F. This attribute has led customers to turn to us when competitors’ coils have come apart due to adhesive failure. Precision layering techniques and flat winding capabilities allow us to produce coils with the highest possible turn density, providing superior performance and sound characteristics. Winding with flat wire, since we do the flattening in-house, allows us to custom fit a customers’ electrical specifications (DCR, turns) into their physical specifications (ID, OD, winding width) for a much more efficient use of space. Electrical testing including resistance, inductance, and turns count testing can be performed to customer specifications. Standard lead time on voice coils is 3 weeks with additional time for new tooling if applicable. We accept blanket orders and can stock items for customers as part of our commitment to provide the highest quality service available
