This Bundle contains a Pair (2) of KRK VXT6 Powered 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 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.
