The XTernal12 is a 500W in-ground subwoofer designed for both commercial and residential environments. Designed with durable, weather-resistant components, the XTernal12 is buried underground with only the vent peaking from the surface. Installation is relatively simple, but considerations should be taken on placements and wire run.

For optimal performance, connect the XTernal12 series subwoofer to a mono subwoofer amplifier like the SMP500 and combine it with our landscape satellite speakers. Additional system configurations can be created for up to eight pairs of speakers using multi-channel amplifiers and/or series-parallel wiring, meaning you get rich audio with clear, deep bass every time you step outside. The XTernal12 is also ideal for theme parks, shopping malls, restaurants, resorts, gardens and other outdoor spaces where bass can enhance the audio experience.

Installation Tips:
For optimal performance, place the subwoofer within 20 feet of the general listening area. To blend the unit in with your outdoor environment, place it near landscape lighting, water fountains, open planters, or swimming pools. Use speaker wires of equal length to maintain balance in sound volume and quality.
