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.
