US Bank Stadium

Morris Light & Sound chose d&b audiotechnik’s GSL line array for audio support of the Final Four held at U.S. Bank Stadium in Minneapolis.

Big Game, Big Sound

After deploying GSL for Kenny Chesney at the venue in 2018, Morris knew that the only loudspeaker that could solve the complex audio challenges of the stadium and event would be d&b audiotechnik’s GSL. The big brother in the well-regarded SL-Series, the GSL system, is unique in that its 2-Way active design features two 14″ LF drivers, two side firing 10” LF drivers combining in a geometry that creates unprecedented low frequency headroom which couples towards the front to increase the LF output and cancels towards the rear by applying cardioid techniques.

The symmetrical arrangement of the neodymium LF drivers around the centrally mounted coaxial MF and HF components allows for a smooth overlap of the adjacent frequency bands in the crossover designs. With the 14” LF drivers being driven from one amplifier channel, all other components are able to be passively crossed over and driven from a second amplifier channel. The horizontal directivity pattern of the GSL is seamlessly maintained down to 45 Hz.

Sporting Event



“The GSL system provided rejection on the court that couldn’t be achieved with any other product. The cardioid properties of the box were able to dramatically reduce excess noise and provide unmatched audio intelligibility.”

All About The Set Up

Surrounding the temporary video board, d&b’s GSL was flown in 8 hangs of 10 cabinets in the round. Additionally, 8 Y10P’s were used on a separate feed as competition speakers to cover the floor. D80 amplifiers were flown on two separate platforms and controlled using the d&b R1 remote software. These elements combined allowed Morris to provide consistent sound across the coverage area from a trim height high above the video board.

A Team Effort

Morris applauds Avant Acoustics, who they worked with throughout the three-day event. “John Hodgson, Robert Ledo and David Wetzel were top professionals.” Haskell said.

“David Haskell and the Morris team are recognized and well respected by the stadium operators,” Day said. “Morris is known as a production company that puts a lot of effort into making these stadiums work for their production. They brought that same experience and effort to help make our events a success.”


Expectations were high after hearing the GSL rig in setup and tech rehearsals- nice high frequency detail, smooth overlap zones and very good direct-to-reflected sound. The system performed very well and delivered PA, music and sound effects for each of three big games. The system had a lot of gas left in the tank while delivering 105dBA and fueling crowd excitement.
