Designed for discreet in-ground installation, this compact subwoofer features a powerful 8-inch (200mm) long-throw driver engineered to deliver impressive low-frequency response down to 38 Hz—perfect for patios, gardens, walkways, rooftops, and other open-air environments where full-range audio is essential but space or visibility is a concern.

Whether you’re upgrading a private outdoor lounge or building a high-end distributed system in a commercial venue, the GSB8 delivers the deep bass and clean design needed for truly immersive outdoor sound.

🔊 Discreet Low-End Performance, Engineered for the Outdoors

The GSB8 is designed to be buried in the ground, with only a small canopy-style port exposed above the surface. This allows it to blend seamlessly into landscaping while still delivering robust bass reinforcement across your outdoor listening area. Its compact form factor makes it ideal for smaller areas or installations where visual impact must be minimal without sacrificing sound quality.

Pair it with JBL Control 80 Series satellite speakers (like the 85M or 88M) to create a complete 360-degree outdoor sound field that enhances everything from ambient background music to energetic entertainment.

🏡 Tailored for Luxury Outdoor Audio Environments

The JBL GSB8 is a favorite among system designers looking to deliver high-quality bass in smaller or design-sensitive environments. Whether installed at private homes, boutique resorts, rooftop lounges, or upscale cafés, the GSB8 enriches the listening experience with tight, well-controlled bass that fills the space without visual distraction.

🔗 Flexible Installation & Commercial-Grade Reliability

The GSB8 supports both standard 8-ohm low-impedance setups and 70V/100V distributed systems, thanks to its integrated transformer. This makes it suitable for a wide range of applications—from standalone patio systems to large, zoned commercial audio environments. Its compact form is especially helpful in installations where space is limited or underground depth must be shallow.

It’s also designed with security in mind: the low-profile port discourages tampering while the underground housing protects the internal driver and wiring from weather and wear.
