OWR-05049 SERIES MINIATURE RECEIVERS

A NEW FAMILY OF EFFICIENT DRIVERS

Ole Wolff is pleased to present a brand new series of receivers using the Deep Drawn Diaphragm Technology™.

This technology offers

  • very high performance
  • very high sensitivity
  • very small form factor for flexible placement inside earpiece

The OWR-05049T receivers are the first on the DDD-technology™ platform.

More variants based on same platform are being developed, completing a full range of receivers optimized for earphone applications.

DEEP DRAWN DIAPHRAGM TECHNOLOGY™

 

The OWR-05049 series  has a very unique diaphragm construction which virtually uses the receivers' full outer diameter
giving it a SPL gain of 4dB compared to a conventional receiver of the same size.

This technique is Patent Pending, PCT/EP2016/059402.

A FAMILY OF THREE

The OWR-05049 series consists of three variants:

  • OWR-05049T-50A, woofer, 50 ohm
  • OWR-05049T-50B, LF boost woofer, 50 ohm
  • OWR-05049T-38A, full range, 38 ohm

RESOURCES

Upon request Ole Wolff can supply Thiele-Small data, 3D CAD drawings and Comsol™ lumped models of the receives to help you in the design process.
