As for the lower end, IS series is comprised of two passive subwoofers, respectively equipped with a 1×8″ or a 1×12″ woofer.
The compact size of both boxes is ideal when it comes to integrate a low-end extension cabinet in a venue, without dragging too much attention to it.
Needless to say the keyword here is: ease of installation and unobtrusiveness. That’s why each single system in IS series comes with a smooth design, Phoenix or Speakon connectors, black or white version.
*Available in black or white finish.
