STADIA STSUB-215 is the companion subwoofer for Stadia & Arena Series, featuring the same ‘OutSide’ weatherproofing system and extending the applicational usefulness of the Stadia/Arena Series still further.

The enclosures are constructed from birch ply finished with ‘outSIDE’, an extraordinarily tough and waterproof elastoplastic coating which interacts with the cabinet material to provide extreme levels of long-term protection. The front grille is treated with an epoxy and polyester-based thermosetting powder paint and matched to an acoustically transparent waterproof sheet, so protecting the components from moisture and other contaminants, while amplifier connections are recessed so that a weatherproof plate with cable retention can be fitted.

The STSUB-215 modules are all fitted with eight (8) M10 rigging points made of corrosion-resistant anodized aluminium alloy (Ergal) allowing plenty of mounting options.
