For the fifteenth Milkshake Festival, held at Amsterdam's Westerpark in late July 2026, production company JUR deployed Alcons Audio systems across nine areas. With eight outdoor districts, one indoor district, nearby homes, and an adjacent road, controlling the direction of low-frequency radiation was a central design concern.
The bass strategy centred on 44 BC543 cardioid systems, each built around three 18-inch drivers. JUR arranged them in purpose-designed directional arrays to steer low-frequency energy toward the audiences while reducing radiation behind the arrays.
The main systems drew on LR15, LR18, LR24, and LR28 line arrays together with RR12, VR8, VR12, and WR20 loudspeakers. BF181, BF362, and BQ211 systems supplemented the BC543 inventory, and 344 channels of Alcons ALC amplified loudspeaker controllers powered the deployment.
The published inventory includes 54 LR18/90, 32 LR24/80, and 44 LR28/80 enclosures among the other models. Almaro and TTM supplied additional stock through the Alcons Ribbon Network. For a second consecutive year, two areas also used WR20 monitors paired with LR18B systems for DJs.
Mix reports that only four noise complaints were received over the two-day weekend. The article does not provide boundary-level measurements or comparable figures from earlier years, however. The directional design is therefore documented in the system configuration, while its effect on neighbourhood noise remains a reported outcome rather than an independently quantified result.
