The new V-Series combines the best of modern technology while getting back to what made KRK an industry standard in professional studios for the past 30 years running. KRK V4 is a two-way, full-range studio reference monitor with professional performance and accuracy for recording, mixing and mastering. It features a 1″ KRK designed Kevlar tweeter and 4″ lightweight KRK designed woven Kevlar woofer. Using Kevlar for both the woofer and tweeter these KRK monitors give you extremely smooth midrange definition without colorization and pristine high-end with tight, controlled low-end, as well as a wide sweet spot and beautiful imaging. An 85W KRK designed, bi-amped Class-D amplifier delivers superior transient speed and up to 110 dB of SPL. KRKs optimized front-ported bass reflex enclosure design avoids boundary coupling to allow flexibility in room positioning. 49 different DSP driven EQ presets deliver superior control for room/desk correction as well as personal taste. The solid aluminum front-baffle and EVA foam pad is like having a built in stabilizer that improves transient response and imaging. Included in the box is the protective grille to be installed for the mobile user.
