AI ten2 S4 Plus specifications & manual

The Basics

The Series 4plus product line consists of a two channel amp head and three speaker cabinets. The head mounts in the cabinets using our exclusive Cabrio Docking System to form three different combo amps. The Clarus amp head uses a class-D power amplifier with a switch mode power supply and a sophisticated, sensitive two channel preamplifier. The speaker cabinets have a 1×10 or 2×10 speaker configuration. The features of the speaker configuration define the specific combo model.

  • The Coda combo has a 1×10 speaker configuration with a poly cone woofer.
  •  The Corus combo has a 1×10 speaker configuration with a paper cone woofer.

Both have a 5 inch extended range driver with presence control in addition to the woofer.

  •  The Ten2 combo uses a 2×10 speaker configuration (one downfiring, one front firing) with poly cone woofers in conjunction with a 2.5 inch tweeter.

Each cabinet type is also available as an extension speaker in either a “Cabrio-ready” configuration or as a fixed extension cabinet (Coda EX, Corus EX or Ten2 EX).
