The KRK Rockit 6 is a solid addition to your home studio or professional setup. You can use these without subs in a small room. There’s no distortion at all and the high end is very clear. These powered speakers do not require amplifier or receiver. You will need a specific cable such as a 1/8th AUX to Phono RCA component to hook these speakers directly to your speaker.

ROKIT 6 Powered Monitor – Generation 3

KRK’s ROKIT 6 G3 (Generation 3) powered studio monitors offer professional performance and accuracy for recording, mixing, mastering and playback. The system consists of a 1” soft dome tweeter and 6” glass-Aramid composite woofer. It delivers high frequencies up to 35kHz, vocal clarity and extended bass response. The proprietary bi-amped, class A/B amplifier grants SPL up to 107dB. The ROKIT waveguide is designed to ensure detailed imaging in the listening position. The front-firing bass port reduces boundary coupling to allow flexible positioning in the room while the engineered surface reduces diffraction distortion. Multiple input connections ensure the ROKIT 6 G3 will easily integrate in any system configuration.

In larger rooms, where smaller monitors might not provide enough headroom, the ROKIT 6 G3 provides enough backup for even larger set ups.
