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.

Flipside brings new life to London’s bars with TW AUDiO

Promising a “modern day pub experience built on traditional values”, one of the UK’s most innovative venue operators, The East London Pub Co., has brought fresh inspiration to two equally historic but radically different London venues, The Lock Tavern in Camden and The Gun in Spitalfields.

St. Leonard Catholic Church Steps Up To TW AUDiO

Realizing that the old sound system was entirely inadequate to their needs, the parish selected AV and lighting systems integrators Sven Pro to design and install a new TW AUDiO sound system.
