!Design

NHT speakers are designed to deliver refined, musical sound from attractive and affordable packages. Our efforts are guided by the study of human hearing and are optimized for real-world use. Every NHT loudspeaker undergoes rigorous testing and quali- ty control at the factory to ensure you years of listening pleasure.

The SW2Si Subwoofer features a custom-designed 10” polypropylene woofer that is capable of accurate low frequency repro- duction to 27Hz, with high output and low distortion. The SW2Si, when combined with the NHT SA-2 monaural subwoofer ampli- fier, comprises the NHT SW2Pi Powered Subwoofer System. For a flatter overall low frequency response and increased clarity, two SW2Si subwoofers may be connected in parallel to the NHT SA-2 subwoofer amplifier, which is designed with enough high current capability to drive two subwoofers (for more power, you may substitute the SA-3 amplifier). Alternately, you can use an external crossover and a monaural amplifier of your choice to create your own powered subwoofer system.

!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, unob- structed 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 symmetrical- ly in the room (such as in two corners). As the SW2Si is not magnetically shielded, do not place it in the immediate vicinity of a television, or picture discoloration may occur.

!Connections

The SW2Si Subwoofer is designed for use with an external crossover and a monaural amplifier. The SW2Si does not have an internal crossover, so it should not be connected to any other amplifier or integrated amplifier unless it has a low-pass filter. Using the SW2Si without a low-pass filter will not damage it, however the resulting sound will be undesirable.

Before connecting the SW2Si to the SA-2 (or any amplifier), it is very important that you turn off the power to the ampli- fier. Proper wiring of the subwoofer is essential to good sound. NHT recommends a minimum of 14 AWG wire to connect the
