Seoul Sound deploys massive K Series concert sound system to complement water effects\u00a0requiring 130-metre throws across nine-city stadium tour<\/em><\/p>\n\n\n\n

\n\n\n\n

SEOUL, South Korea – September 2025<\/strong>\u00a0– When PSY dropped “Gangnam Style” in 2012, he didn’t just break the internet\u2014he redefined what a global cultural phenomenon could look like. The track became the first YouTube video to hit one billion views, sparked flash mobs worldwide, and turned the South Korean artist into an international icon who bridged K-pop with mainstream Western\u00a0audiences\u00a0years before BTS and Blackpink followed suit.<\/p>\n\n\n\n

His annual Summer Swag tours have become legendary in their own right, drawing 35,000-capacity crowds across South Korea’s biggest stadiums for water-soaked celebrations that blur the lines between concert and festival. This year’s nine-city tour presented audio provider Seoul Sound with their most ambitious challenge yet: delivering pristine audio coverage across massive venues filled with elaborate water cannons and sprinklers, while accommodating surprise guest appearances from K-pop royalty including Ros\u00e9, G-Dragon, and J-Hope\u2014each bringing their own unique sonic requirements.<\/p>\n\n\n\n

Water Meets Wattage: Solving Stadium-Scale Audio Challenges<\/strong><\/strong><\/p>\n\n\n\n

PSY’s Summer Swag concerts are renowned for their four-hour water play spectacles, but all that H2O creates serious headaches for sound engineers. Traditional delay towers would interfere with the water effects that define the show experience.<\/p>\n\n\n\n

“The artist and tour producers specifically requested K1 as the main system to achieve 130-metre throws without requiring any delay towers,” explains Soonil Yoon, FOH Engineer at Seoul Sound. “With water cannons and sprinklers occupying much of the audience area, we had to rely entirely on the main hangs to provide uniform coverage to the entire audience.”<\/p>\n\n\n\n

Seoul Sound, working with sister company Klausys, an L-Acoustics Certified Provider, turned to Soundvision 3D modelling software to optimise each venue configuration. The tour demanded unique setups for varying capacities, weather conditions, and the integration of water effects with live sound reinforcement\u2014all while accommodating PSY’s diverse musical palette spanning K-pop, rap, rock, EDM, and intimate ballads.<\/p>\n\n\n\n

The Summer Swag 2025 rig featured main left-right arrays of 16 K1<\/a> and four K2<\/a> per side, with eight K1-SB<\/a> subwoofers flown behind each hang. Side-fill extension hangs of eight K2 boxes per side handled wider audience coverage, while 14 pairs of Kara<\/a> enclosures provided front-fill across the stage width. Fifteen SB28 subwoofers per side were concealed beneath the stage deck to maintain powerful low-end response while preserving valuable ground space for water-play effects. The entire flown system runs on LA12X<\/a> amplified controllers, with ground subs and side-fills powered by LA8<\/a> units via AES\/EBU network protocol.<\/p>\n\n\n\n

“Sometimes the ‘less is more’ principle plays a big role for shows like this,” notes Soonil. “Shows are already complex enough. With L-Acoustics systems, you can challenge yourself to provide massive sound coverage through a relatively minimal, simple straightforward<\/p>\n\n\n\n

Weathering South Korea’s Summer Extremes<\/strong><\/strong><\/p>\n\n\n\n

South Korea’s brutal summer conditions added another layer of complexity. Hot, humid days gave way to temperature and humidity swings between day and night, while rain and show water effects turned load-ins into logistical nightmares. The production team adapted by scheduling all setup work during nighttime hours, while the K Series equipment’s robust construction proved reliable throughout the demanding outdoor environments.<\/p>\n\n\n\n

Recognition from a Perfectionist<\/strong><\/strong><\/p>\n\n\n\n

PSY, known throughout the industry for his exacting standards, publicly acknowledged Seoul Sound’s exceptional work during the Daejeon show. He gave special recognition to FOH engineer Soonil Yoon and the entire crew, crediting their outstanding audio delivery throughout the tour\u2014the result of extensive rehearsals before the trek kicked off.<\/p>\n\n\n\n

The tour’s success demonstrated how strategic constraint management can lead to superior results. By eliminating delay towers, Seoul Sound not only addressed the water effects challenge but streamlined the entire production workflow, proving that innovation often comes from working within limitations rather than around them.<\/p>\n\n\n\n
