The V4S4-NA from KRK represents the 4th iteration in their V series of powered reference monitors. This two-way monitor sports a 1" Kevlar tweeter and 4" woven-Kevlar woofer—both of them custom designed by KRK—as well as bi-amped Class-D amplification to engender an accurate transient response. It's capable of delivering 85W total (55W from the woofer, 30W from tweeter), and delivers a frequency range of 50 Hz to 24 kHz at an SPL of up to 110 dB. A front-ported bass-reflex enclosure design protects against boundary coupling, providing you options when it comes to room placement. Compounded with 49 user-selectable DSP-driven EQ options, a solid aluminum front-baffle, and a built-in EVA foam pad, the monitor gives you many options in preserving frequency transparency and transient response in many less-than-optimal room scenarios. You can route signal to these monitors through its Neutrik combination TRS/XLR jack, and even stay current with future updates and features via USB.
