The ES-290 Biradial Horn is a direct competitor to the classic Yuichi A-290.  The ES-290 takes all that's great about the much loved A-290 and improves many aspects to it's overall performance.

ES-290 Flare Geometry 

A-290 Flare Geometry 

The complete wrap-around geometry drastically reduces edge diffraction off the horn mouth.  This improves time domain performance such as spectral burst decay for lower noise floor, improved high frequency detail retrieval, and off-axis performance. 

No Throat Adapter

The traditional throat adapter from round to square has been eliminated.  This transition now occurs over the entire depth of the horn which provides a very smooth physical transition.  Also, the horn throat angle is matched to the compression driver for a smooth transition between driver and horn. 

No Dispersion Fins 

Superior off-axis performance is achieved by virtue of the ES Flare geometry eliminating the need for dispersion fins.
