Monoprice Outdoor 2.1 Speaker System with 8-inch Subwoofer and 2.5-inch Satellites (3 piece) - Sycamore Series

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
