The T20i is a consequential transformation of our users requirements. A compact, 30 cm slim 2 × 10“ / 1.4“ top in a symmetric construction, perfectly suitable for use in upright and crosswise applications.

Thanks to the sophisticated driver arrangement and passive crossover the T20i has a constant directivity, horizontally as well as vertically. Particularly installations where low ceilings are an issue and conventional two-way loudspeakers are a mere compromise, the T20i shows its true potential.

The T20i comes standard with a rotatable 90° × 50° horn. With the optional 60° × 40° horn thus there are four different dispersion angles possible.
