KRK VXT4 - Design Features

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

Facilitates the smooth passage of air molecules which reduces port
turbulence at high signal pressure levels. Front ring to avoid wall / corner
coupling.

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.

Woven Kevlar Cone

The inter-molecular hydrogen bonds of Kevlar give the cone high tensile
strength for it’s light weight. Kevlar also maintains its strength and
resilience over a wide temperature range. The lightweight and resilient
properties of Kevlar reduces distortion and delivers extended low-end
performance as compared to cones made from paper or polypropylene.

Proprietary Woofer Design

The aluminum pole and vented formers remove heat and reduce the
effects of power compression ensuring audio performance is consistent
and does not deteriorate over time.

Multiple Protection Circuitry

Thermal, over voltage and over-current circuitry is employed in the
design. There is also a switchable limiter which will protect the unit from
transients in the signal path.

Ground Lift

Allowing the disconnection of the ground terminal to help resolve issues
such as hum and buzz caused by ground loops in poorly congured
power systems.
