5-300/A8/25HEX

A classic midrange speaker that due to its phase plug technology significantly improves its omnidirectional behavior in the upper midranges. An “open” and “airy” sound reproduction is typical for the front open construction. The intensity of this characteristic increases steadily with increasing frequency which makes a homogeneous transition to a wide omnidirectional tweeter much easier.
