PNW 57 by Audiocontrol Description
The PNW 57 from Audiocontrol is an innovative 5"x7" coaxial system equipped with advanced features. This model is characterized by a edge-reinforced steel frame for additional structural strength and a black anodized voice coil former for excellent heat dissipation. One of the special features is the linear double roll surround for precise cone movements and the complex, FEA-calculated motor for efficient operation. In addition, the stiff, polyglimmer-coated cone provides optimized sound reproduction. This is complemented by a rear-damped hybrid silk dome tweeter for extended frequency response and a concentric point source design for smooth sound transition.
