An Active / Passive Bypass Switch on the input panel allows the VTC N4 to operate as a full range cabinet with its internal passive crossover network, making it ideal for repeater and side fill applications where quick plug and play connection to a single amp channel is required. In Active mode, the internal crossover is bypassed allowing efficient bi-amp operation of the N4 for critical monitoring and sound reinforcement applications.

The horn structure is made from high-pressure die-cast polyurethane foam which reduces resonances and vibrations and assures maximum strength. The 60 by 50 degree elliptical shaped horn provides low distortion and a spherical wave-front, avoiding reflections and other disadvantages usually associated with diffraction horns.

An integrated 1 3/8-inch (3.5cm) pole mount adaptor allow the N4 to be used on standard heavy-duty speaker stands for side and center-fill applications where maximum SPL and coverage is required from a compact cabinet source.

Built for touring applications, the 80lb (36.4kg) VTC N4 uses a solid 5/8-inch (15mm) 11-ply Russian Birch plywood cabinet construction, integrated handles and a heavy-gauge perforated all metal grille to protect the speaker components.
