The main design considerations behind the Arcline 6 were versatility and ease of use. Portability and a sophisticated rigging system that requires no specialised knowledge by the user were also high on the list.
In order to avoid the use of multiple enclosures, yet ensure a wide enough horizontal coverage pattern, the Arcline 6 was conceived with a 120 degree dispersion in the horizontal plane. This dramatically improves the perceived sound qual i t y and definition, as well as reducing setup time by eliminating the need to hang multiple columns to achieve the needed angle of coverage.
Placing all the components on a virtual arc with a true 120 degree dispersion has resulted in a highly-uniform polar pattern that allows all of the audience members to experience a similar sound quality.
Traditional HF spacing and path length compensation among line source enclosures has almost always meant a compromise in HF performance; thus a new design of waveguide has been employed for the Arcline 6. The new waveguide and common virtual feed point allows a flat response up to 21 kHz, even when coupled with multiple enclosures. The ability of the Arcline 6 to form a true cylindrical wavefront when used in multiples is key to its exceptionally smooth transition from near-field to far-field coverage.
