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.
