  • 3 x 1″ neodymium high frequency compression drivers
  • Electronic high frequency driver protection
  • Integral flying system


The two-way passive full range Arcline 6 is versatile, portable, and intuitive in use, made possible by the wide 120 degree horizontal dispersion that dramatically improves the perceived sound quality and definition as well as reducing setup time, and obviating the need to deploy multiple enclosures.


Placing the four 6.5″ neodymium low frequency drivers and three 1″ neodymium high frequency drivers on a virtual arc with a true 120 degree dispersion results in a highly uniform polar pattern that allows all of the audience members to experience a similar sound quality. Traditional high frequency driver spacing and path length compensation among line source enclosures has almost always meant a compromise in high frequency performance; and therefore a new design of waveguide was employed for the Arcline 6, with the common virtual feed point generating flat response up to 21kHz, even when multiple enclosures are coupled. The ability of multiple Arcline 6 enclosures to form a true cylindrical wavefront is key to their exceptionally smooth transition from near-field to far-field coverage.


The lightweight 15mm (5/8″) birch plywood enclosure features an integral flying system and textured polyurethane finish, and two Neutrik speakON™ NL4 connectors provide input and link through connections. An optional winch up stand allows two Arcline 6 units to be stand mounted and tilted for optimal coverage.
