Genelec's G Series active two-way speakers have a seamless design that flows gently from the woofer to the tweeter. Genelec chose the smooth design to reduce acoustic reflections that can interfere, or diffract, the sound. Specifically, the tweeter is surrounded by a Directivity Control Waveguide (DCW), and it's designed to match the frequency response and directivity characteristics of both drivers. The goal is smooth frequency response both on-axis and off-axis. <iframe width="640" height="480" src="//www.youtube-nocookie.com/embed/WxPsWsWFOGQ" frameborder="0" allowfullscreen></iframe> Read more about the Genelec G Series Speakers and F Series Active Subwoofers.
