Belgian loudspeaker manufacturer Audiofocus will reveal the latest additions to its touring and installation subwoofer ranges at ISE 2026 (stand 7F100).
115SG is an all-new ground stacking design built around a single 15” LF transducer and utilises Tetracoil double voice coil technology to achieve tighter control, greater power, and enhanced transient response. The loudspeaker achieves a peak SPL of 131dB and covers a frequency range of 35Hz to 100Hz.
In addition to the passive 115SG, the new subwoofer is offered in two self-powered variants: the 115SGa, optimised for sustained performance in demanding applications such as EDM, and the 115SGaDUO, which adds a pair of speakON connectors for plug-and-play powering of top speakers. 115SG can be driven by Audiofocus A series amplifiers, with Powersoft Armonia presets also available.
“As well as being the sub of choice for our Isolde AP108 and Cyris CX8 point source cabinets, 115SG will be a crucial building block for multiple future Audiofocus systems,” explained Audiofocus CEO and founder Ann Leroy. “For this fifteen-inch range we have applied all the lessons we learned with our popular 118S subwoofers, retaining the winning formula of Tetracoil transducers and a focus on high SPL in a compact footprint.”
All 115SG variants are available now and are built to order at the Audiofocus facility in Belgium.
