The SL-Series. Directivity has a new drive.

The SL-Series are the only modern line array systems to offer full broadband directivity control. The debut of the KSLi System extends this sonic advantage into new territory: permanently installed audio.  The KSLi System is a no compromise solution that unifies the unparalleled headroom, clarity, and control of the SL-Series with the most powerful installation platform in the d&b range: the 40D amplifier.

Predictable dispersion behavior, enhanced high frequency resolution and built in efficiency from start to finish. Out on tour or fixed in place, there is a complete SL-Series package for any performance.

On the road.

A seamless combination of GSL and KSL answers both the sound reinforcement and noise control needs of any mobile event. A complete package of accessories, transport touring solutions and an efficient rigging procedure teams with the d&b infrastructure for planning, control, routing and cabling. Unparalleled flexibility meets unrivaled scalability, venue after venue.

Off the road.

The KSLi System represents the first no compromise audio solution designed expressly for use in medium to large scale fixed installations. Inheriting the same performance characteristics that give the SL-Series its sonic advantage, KSLi can be precisely fashioned to satisfy individual project requirements. Special construction, weatherization, and aesthetic features can all be designed by the d&b Custom solutions team. The result? A complete dedicated installation solution with broadband directivity embedded in its DNA.

The technical details.

The GSL, KSL and KSLi Systems employ a combination of techniques to achieve full bandwidth constant directivity pattern control. All SL-Series loudspeakers are constructed using a 2-Way active design. This features a low frequency geometry using cardioid technology along with a driver and port layout to produce directivity matched perfectly with the coaxial arrangement of a high efficiency midrange horn and the waveguide mounted high frequency drivers.

SL-Series loudspeakers are complimented in the very low frequencies by a range of cardioid subwoofers including SL-SUB, KSL-SUB and KSLi-SUB, with variants available for ground stacked applications. While GSL and KSL are driven by D80 amplifier, the 40D amplifier reaches new performance heights within the d&b installation range and sits at the heart of the KSLi System package. 

The ability to address such a breadth of application scales and styles, both indoors and out, facilitates high return on investment from wide ranging venue utilization and flexibility of deployment in both mobile and installation situations.

Getting to know the SL-Series.

In the videos below, Werner “Vier” Bayer, Product Manager, and Matthias Christner, Head of R&D System Design, explain what’s inside the box, the acoustical targets, the evolution of the applied techniques and enabling technologies as well as the ‘full’ SL-Series Mobile package.

A step by step guide on the SL-Series rigging methods and modes can be found in Video tutorials. d&b will also offer technical training on the SL-Series. These workshops can be found in the Education calendar.



Designed for use in medium to large scale installations, the KSLi System conquers new performance possibilities with a complete package that includes the most powerful installation amplifier in the d&b portfolio and a range of customization options.
