99–113 mm / 4" Voice Coils for Professional Woofers

99–113 mm / 4" voice coils for woofers and midrange speakers are used in professional loudspeakers, PA systems, pro audio applications, and high-power drivers.

This diameter is typical for professional woofers and audio systems where high thermal capacity, large winding area, and mechanical stability under heavy load are required. 4" voice coils are suitable for professional repair, recone work, and rebuilding high-performance speakers.

For correct replacement, it is important to check the inner diameter, impedance, winding height, wire material, number of layers, and former type.

Our catalog includes 99–113 mm / 4" voice coils for repair, recone work, and rebuilding woofers, midrange speakers, and professional drivers.
