The Arcline 8 is versatile, portable and intuitive to use. This is made possible by a host of new technologies that dramatically improve the perceived sound quality and definition. An all new advanced rigging system also reduces setup time and obviates the need for more than one person to rig multiple enclosures.

The Arcline 8 delivers a true 110 degree dispersion and results in a highly uniform polar pattern that allows all of the audience members to experience uniform sound quality across the entire sound field. Traditional high frequency driver spacing and path length compensation among line source enclosures has almost always meant a compromise in high frequency performance, so a new design of high frequency horn was developed

for the Arcline 8. Extensive FEA modelling was used both to evaluate and optimise the waveguide. A new phase shading device has also been implemented to allow multiple Arcline 8 enclosures to form a true cylindrical wavefront by splitting two acoustic sources into four, with the acoustic centre positioned optimally for coupling in both the horizontal and vertical planes.

The lightweight 15 mm (5/8”) birch plywood enclosure is finished in a textured TourCoat polyurea finish, and features a unique flying system that allows rigging angles to be pre-selected before the flying the system. Two Neutrik speakON™ NL4 connectors provide input and link through connections.
