SoundTube speakers deliver more intelligible sound through Broad-Beam dispersion technology, which distributes the higher frequencies of sound in a wider, more effective pattern than conventional speakers. This allows for wider spacing of speakers and fewer speakers overall, without sacrificing intelligibility, with the added benefit of reduced installation time and associated costs.

Perfect for sound systems in shops and restaurants as well as entertainment venues, schools and colleges.
