5-302/C8/25HEX

A midrange speaker with phase plug technology that is based on the 5-300/A8/25 Hex. Equipped with a kapton voice coil it is able to naturally reproduce fastest impulses in the lower basic sound range even at high amplitudes. On the other hand the upper midrange is reproduced more softly. A front open construction provides for the typical “open” and “airy” sound
