The SB loudspeaker is a compact device designed to perform in a wide range of public address and sound reinforcement applications. It is a 2Way passive system, consisting of two proprietary 5-inch low frequency driver and one 1-inch high frequency dome tweeter loaded with a horn, housed in a vented enclosure.

The enclosure is black, white or any RAL (on option) epoxy painted and fitted with M8 screws on top and bottom and on each side. On the back, two Speakon connectors allow easy parallel connection.
