7-300/A8/32 Hex

7-300/A8/32 Hex


A classic woofer/midrange speaker with a phase plug for 2 way loudspeaker boxes. Its special sound characteristics are based upon this technology and the herewith combined front open construction. The sound that above all provides for a special charisma in the upper midrange, suits perfectly with all tweeter systems with wide room image. An effective box construction allows the listener literally to dip into the music. We recommend a combination with the air motion system ETON ER4 using a dipole construction
