LD Systems Stinger Sub 18AG3

The LD Systems Stinger Sub 18AG3 is a powerful 18‑inch active subwoofer built for events that need tight, controlled low‑end without the bulk of a full concert rig. It delivers deep, punchy bass that pairs perfectly with our powered speakers, making it a great choice for DJs, live bands, corporate functions and outdoor events.

This sub is designed to handle real‑world hire situations — solid build quality, reliable performance and enough output to comfortably fill medium‑sized venues. Whether you’re running a DJ system, a live music setup or a full PA system, the Stinger 18AG3 adds the low‑frequency impact that smaller speakers can’t deliver on their own.

If you’re building a complete sound system, this subwoofer pairs exceptionally well with our:

• LD Systems Stinger 15 A G3

Well-braced bass reflex enclosure

The Stinger Sub 18AG3 is a real workhorse throughout. You can use it in both horizontal and vertical orientation. As a result, you can use multiple subwoofers and stack them together. In order to offer the user extraordinary strength and durability; the Stinger Sub 18AG3 is made from a rigid 18 mm birch ply and coated with ultra-tough polyurea. It further sports a steel front grille, M20 threaded pole insert, stacking recesses and ergonomic handles for easy transportation. The Stinger Sub 18AG3 will truly deliver professional sound reinforcement and additional accessories to facilitate live and installed applications.

Rear Panel

On the rear panel of the Stinger Sub 18AG3, you will find 2x balanced line inputs that use an XLR / 6.3 mm jack combo. These are line inputs for both the left and right channels. When using both inputs; the signal will be summed as Mono. The use of unbalanced cables (e.g. mono jack) is also possible, however, balanced cables are preferable due to the greater noise immunity. 2x balanced THRU line inputs are also present. These also use 3-pin male XLR sockets. Aside from the rotary encoder for the total volume you also have several mode switches available. These modes offer 80 Hertz, 100 Hertz, 120 Hertz and Cardioid. Lastly, there is a Power IN, Power OUT and Power Master Switch on the rear of the subwoofer.
