Directivity control and cardioid technology enable loudspeaker systems to focus acoustic energy exactly where it’s needed: on the audience. This minimizes unwanted sound in other areas, reducing reflections that can blur clarity and ensuring compliance with increasingly strict environmental and noise regulations. For event organizers, system designers, and local authorities, this means fewer complaints, easier regulatory approval, and a better experience for everyone involved.

At d&b, our “Democracy for Listeners” philosophy is built on the belief that every audience member deserves the same sound, no matter where they are seated. Our obsession with directivity and cardioid control has led to innovations that deliver precisely defined dispersion patterns across the widest frequency range, including the challenging low frequencies. 

Experience the technology

Find out more about the latest in broadband directivity and cardioid technology:

• SL-Series (GSL, KSL, XSL): The first fully integrated large-format loudspeaker systems to deliver true broadband directivity, including low-frequency cardioid behavior.
• CL-Series (CCL): Bringing directivity to more venues, CCL makes “cardioid magic” accessible for theatres, houses of worship, corporate events, and more.
• 24C Column Loudspeaker: Compact yet powerful, with precise dispersion for challenging spaces.

Join us for the d&b Directivity Day and explore the benefits of broadband directivity control and low-frequency cardioid behavior. Expect a deep dive with short theory sessions followed by listening sessions - all free of charge.
