True 2.1 System: The subwoofer employs a 2-way, 12db crossover at 200Hz, so it uses all frequencies below 200Hz and sends all frequencies above 200Hz to the satellite speakers. Heard Not Seen: With the body of the subwoofer and the speaker wires buried in the ground, the system fills your yard or patio with great sound, while maintaining a low profile that doesn't look out of place in your yard. Easy Install: Rather than needing to run separate wires from the amplifier to each speaker, only a single, 4-conductor wire needs to run from the amp to the subwoofer, then a shorter pair of 2-conductor wires run from the sub to the satellites. Modular: The system is designed to be extended by using additional subwoofers and/or satellite speakers. Need more bass? Add another subwoofer. Need more coverage for a large room? Add another pair of satellite speakers. It doesn't get any more simple than that. Great Sound in the Ground: Enjoy rich and full sound in your yard or patio. T
