KRK V4S4 Active Studio Monitor

The KRK Series 4 continues KRK Systems' industry standard line of award-winning studio monitors, meeting the needs of professional audio engineers and musicians around the world. The V4 S4 is a compact, 4" near field monitor ideal for home, bedroom and small-room monitoring applications where accuracy and detail is paramount.

A versatile active monitor, tuneable to any workspace

The V4 Series4 features a Class D, bi-amplified 2-way design. Following in the footsteps of the Rokit and VXT series monitors, with a front ported bass reflex design for improved accuracy in smaller room setups. The iconic yellow KRK cone is a custom designed Woven Kevlar woofer, capable of consistent, reliable performance even at lower SPLs, paired with a custom designed 1" Kevlar tweeter. The V4 S4 also ships with a protective grille for mobile broadcast applications.

Fine-Tuned Mixing

With an unrivalled array of EQ settings and Level Attenuation available on the back panel, you can fine tune the output of the V4S4 to your personal preferences or optimise them for any size room. No longer does an irregular mixing space or control room become an issue to get a reliable mix.

The V4 delivers everything you'd expect from a world-class studio monitor - low distortion at high SPLs, amazing clarity and imaging alongside precise room controls to find the perfect balance.
