🔊 Invisible Bass, Maximum Impact

With the GSB12’s in-ground design, only a small canopy port remains visible, allowing the subwoofer to disappear into landscaping while still delivering rich and dynamic bass. Its discreet profile makes it perfect for professionally landscaped gardens, pool areas, restaurants, rooftops, resorts, and theme parks. Unlike surface-mounted subwoofers, the GSB12 maintains a clean visual aesthetic while dramatically enhancing the low-end presence of your outdoor audio system.

Pair it with JBL Control 85M or Control 88M satellite speakers to create a seamless, immersive full-range audio experience in any open-air environment.
