Design
NHT products 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 product
undergoes rigorous testing and quality control at the factory to ensure you years of listening pleasure.
The NHT SA-2 Subwoofer Amplifier is a powerful and versatile monaural low frequency amplifier. The SA-2 and
SW2Si passive subwoofer together comprise the SW2Pi Powered Subwoofer System. Additionally, the SA-2 is
designed to power the subwoofer sections of NHT tower speakers when connected in biamplified
rations.
The SA-2 is optimized for powerful low frequency reproduction, with a host of convenience features and
sufficient high output capability to drive up to two subwoofers. Its discrete Class G design enables cooler
operating temperatures, employing a massive power transformer and dual-rail power supplies for high output
and low distortion. Only high-precision, low-noise componentry is used in the crossover circuits, for seamless
blending with any loudspeaker.

Placement

The SA-2 amplifier's stand-alone design allows it to be placed either with other electronic components in the
system or on top of the SW2Si subwoofer enclosure.
Note: To prevent the SA-2 amplifier from overheating, always be sure to provide adequate space for
proper ventilation.
