8. the Curves Our new RoKit has radically curved surfaces for a reason it sounds better Traditional rectangular speakers suffer from diffraction as sounds leaving the edge of the cabinet are reflected back into the sound field causing phase distortion The Generation 2 RoKit series virtually eliminates diffraction and provides a wider sweet spot with radically engineered curved surfaces Waveguide Design Your Mixes Should Be Three Dimensional Not Flat When attempting to create a mix that has the proper panning depth and frequency response it is crucial to have excellent imaging with proper phase characteristics The waveguide surrounding the tweeter is critical for this purpose A good waveguide provides high frequency pattern control and focuses the sound outward away from the cabinet not along the plane of the cabinet where waveform interaction can cause phase problems with increased diffraction At KRK we pride ourselves on our waveguide designs as being one of the most critical components to our award winning performance but our good looks don t hurt either Port Design Don t Get Bitten From the Rear Take a look at competitive monitors and you ll find ports on the back of the cabinet These rear firing ports tend to create bass coupling with walls and corners amplifying low frequency information which will color your mix talk about junk in the trunk The superior design of the KRK Generation 2 RoKits include front firing p
