HiFi Multi-Driver Receivers

Balanced armature receivers for HiFi multi-driver and hybrid earphones — compact mid/high-frequency units with low-impedance options.

HiFi multi-driver earphones are built around carefully chosen drivers. Whether you manufacture universal-fit monitors, custom-molded IEMs or stage monitoring systems, the receiver determines the character of the sound — its efficiency, its frequency balance and its consistency from pair to pair.

Matching the driver to the design

The EWDK and EWDB series offer lower DC resistance options that can be a good fit for designs needing higher output per drive voltage. Non-tube variants give monitor builders direct coupling flexibility inside the shell, while tube variants simplify acoustic channel routing.

Consistency for professional audio

Professional users compare units side by side. Our receivers are 100% tested before shipment and matched pairs can be arranged on request, so left and right channels stay within your tolerance target.

From evaluation to volume

Start by requesting samples of the models below. Evaluate frequency response and impedance against your crossover and amplifier design, then scale up with the same engineering support for custom tuning and production.
