The Electro Voice ZLX 12 G 2 is a 2-way passive speaker with drivers developed by
A horizontal dispersion angle of 90° enables a wide sound distribution sideways, while a vertical dispersion angle of 60° distributes the sound upwards and downwards in a more limited area. In addition, the speaker can be set to a 23° kickback position for better directivity and increased clarity on stage. Two speaker twist connectors on the rear are used to connect the speaker cable and to loop through the audio signal. Last but not least, three carrying handles on the top, bottom and left-hand side make it easy to transport the robust speaker.

When wiring amplifiers with loudspeakers, the type of loudspeaker plays a decisive role in the choice of cable required.
Passive speakers require a specific, two-pole speaker cable for connection to an amplifier. This cabling is necessary because the amplifier and the speaker are physically separated from each other in a passive setup. Depending on the connectivity of the amplifier and speaker, "speaker twist" or 6.3 mm jack plugs (speaker cable - not instrument cable) are usually used.
