DESCRIPTION
Eliptical waveguides
Full range models feature a 90° x 60° Elliptical Waveguide
In real-world terms this means that the higher frequencies can be heard with definition at 90° in the horizontal plane, and 60° in the vertical.
All full range models in the Impact-X series use this same elliptical waveguide design which makes for controllable coverage when using multiple Impact series loudspeakers.
