KRK VXT 8 Pair Powered Monitors This Bundle Contains: Two (2) KRK VXT 8 Active 2-Way Studio Monitors. ABS (Acrylonitrile Butadiene Styrene) Foam Enclosure. High density / low resonance material giving improved structural integrity and rigidity resulting in an extended low-end response. Allows the internal design to have complex shapes and non-parallel walls, increasing rigidity and reducing internal nodes. ABS also has extremely high impact resistance and excellent damping characteristics which reduces cabinet resonance. Front Firing Radiused Non-parallel Ports Radiused Enclosure Edges. Eliminating diffraction and phase distortion results in improved imaging characteristics as well as a wider sweet spot at the monitoring position. Silk Domed Tweeter The domed tweeter is comprised of true silk for fast transient response. Silk construction reduces ear fatigue and the tweeter waveguide geometry ensures HF directivity.
