An O-Line module uses a line of five custom-designed dome tweeters, with a spacing of only 21mm between each element. The result is sidelobe-free vertical dispersion from the high frequency section. The ‘cones’ of the two custom-designed LF drivers are sculpted from an ultra-light, stiff material and precisely follow the ideal contour of the HF horn walls (patent pending). This provides constant horizontal directivity from low mid, right up to extreme high frequencies.

Rather than applying DSP to a traditional column, O-Line’s vertical beam-forming is achieved by physically articulating individual array modules to curve the array. The actual array configuration for a specific venue is determined by powerful, patent pending optimisation software, which makes intelligent judgements about the ‘goodness’ of the array’s SPL distribution against objective target functions.

O-Line arrays are constructed by simply connecting individual modules together in column lengths of 4 to 24 units as determined by the software.

O-Line modules are finished in a neutral light grey and combine to form aesthetically pleasing, variable length arrays, of outstanding audio quality that will enhance even the most demanding architectural environment.
