Placement
Contrary to popular belief, subwoofers are sensitive to placement. Experimentation is the key to finding the best arrangement in your listening environment. Generally, a subwoofer should be located in the same horizontal plane and along the same wall as the main speakers. Low frequencies produce long wavelengths and thus interact with room boundaries significantly. Placing the subwoofer nearer to a room boundary (walls, corners) will tend to increase its bass output, but may result in “boomy” or “muddy” sound. Conversely, placing the subwoofer farther away from room boundaries will tend to decrease its bass output, but may result in improved articulation and clarity.
Position the subwoofer so that it does not radiate sound directly into a wall or floor, and ensure that it faces into the room, unobstructed by large furnishings. If you are using two subwoofers, the greatest improvement in low frequency response is achieved by placing the second subwoofer on the opposite side of the room from the first. Avoid placing the two subwoofers symmetrically in the room (such as in two corners). As the SW3S is not magnetically shielded, do not place it in the immediate vicinity of a television, or picture discoloration may occur.
Connections
The SW3S Subwoofer is designed for use with an external crossover and a monaural amplifier. The SW3S does not have an inter- nal crossover, so it should not be connected to any other amplifier or integrated amplifier unless it has a
