PK Alliance member BNE Productions anchored the main stage of Bass Canyon 2025 at Washington's Gorge Amphitheatre with a massive Trinity Black / T10 robotic line source system, maximizing the impact of sets by Sullivan King, Wooli, ATLiens – and festival founder Excision himself.
Set on a cliff above the Columbia River, the Gorge is among the most breathtaking venues on Earth, and Bass Canyon its heaviest annual test. Since the festival's inaugural 2018 edition, PK Sound systems have delivered its signature low-end – a partnership rooted in Excision's decade-plus history with the brand.
The 2025 deployment, with FOH and system engineering by Aaron “Zipper” Zuber, used PK's patented Multi-Axis Robotics to focus coverage on the amphitheatre's sweeping bowl while protecting the campgrounds and surrounding areas from spill.

The Gorge is as difficult as it is beautiful. Its bowl is asymmetric and vertically extreme, dropping steeply from the lawn to the pit with the river canyon open behind the stage – geometry that a fixed rig can only approximate. Answering it in the air, by re-articulating the arrays to the terrain rather than rebuilding the hang, is what lets the system stay even from the rail to the last row of grass.
It follows an equally monumental 2024 edition, where PK Alliance member Logic Systems fielded more than 200 PK modules: main hangs of 18 Trinity Black over three T10 per side, 16 flown T218 subwoofers per side, a 50-box G218 sub wall, and extensive out-fills, delays, and front fills.
“PK's ability to control vertical and horizontal dispersion remotely while the arrays are in the air is a game-changer that ensures the best possible listening experience for the audience,” the Logic Systems team noted in FRONT of HOUSE Magazine's coverage of the festival. In the A1's blunter summary, the subs “absolutely stomp.”
Between BNE on the West Coast and Logic Systems in the Midwest, Bass Canyon has become an annual demonstration of the PK Alliance's depth – different partners, the same uncompromising result.
