The flat setting is great for most environments, but low, mid, and high frequency presets can be adjusted to help compensate for common trouble spots in different sound environments. Matching drivers Made with Kevlar ensures the same sonic integrity on every single frequency, minimizes listening-fatigue, and offers an incredibly balanced listening experience. A scientifically designed high-quality speaker enclosure and newly-designed Front-Firing port offer exceptional low-end extension, punch and flexible room-positioning.High density iso-foam pads decouple the speaker from the surface for improved clarity while fluid mechanics fully tuned to the entire system result in a deep and dynamic listening "sweet-spot" with incredible Imaging and 3D soundstage. A new custom designed efficient class D power amp reduces operating temperatures to retain better audio integrity while a built-in brick wall limiter automatically engages at maximum amp-level to maintain a balanced sound, protect the system, and offer better and wider dynamics. Although truly affordable, price isn't even in the rokit conversation-professionals choose rokits for their time-tested and reliable results. The new rokit generation 4 line actually is rokit science.
