Andertons Music Co published video from Guitar Summit 2025 in Mannheim showing the Line 6 Helix Stadium XL, the larger of the two Stadium floor units, with Line 6 chief product designer Eric Klein¹. The videos were published on September 27 and 28, 2025²¹.

Klein described the Agoura modeling methodology as "the biggest pivot that Line 6 has made in our 30-year history at this point," and said the company first modeled the HX models from its 3.8, 3.7 and 3.6 updates to test the process¹. He said version 1.0 has 40 Agoura channels¹. Klein described modeling as digitally recreating a product at component level, "down to the capacitance of the length of wire"¹.

Features Klein and Andertons' Lee Anderton discussed include an 8-inch touchscreen, capacitance-sensing footswitches, a Focus view that morphs between five zones of an amp or effect, a search tool, preset info pages, a built-in matrix mixer with separate control of quarter-inch, XLR and headphone outputs, and a Showcase playback engine with eight stereo tracks¹. Klein said Proxy, Line 6's capture technology, is not out yet and is committed for release in 2026, and that it is cloud-based¹. He said the XL arrives at the end of 2025 and the non-XL in early 2026¹.

Line 6's announcement put U.S. advertised prices at $2,199.99 for the Helix Stadium XL Floor and starting at $1,799.99 for the Helix Stadium Floor, with reservations from June 25 and availability in Fall 2025 and Winter 2025 respectively³⁴. Guitar World listed a launch price of $2,199 and specifications including Bluetooth, WiFi and MIDI, four effects loops (or two stereo), stereo XLR and quarter-inch outputs, S/PDIF in and out, USB C and USB A, dimensions of 19.4 by 10.1 by 3.6 inches and a weight of 11.5 lbs⁵. Line 6 said existing Helix and HX presets can be loaded into Helix Stadium³⁴.
