"The SW2Si Subwoofer features a custom-designed 10” polypropylene woofer that is capable of accurate low frequency reproduction to 27Hz, with high output and low distortion. The SW2Si, when combined with the NHT SA-2 monaural subwoofer amplifier, 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."

both items are in perfect working order. The amp has a small section where the paint chipped off on the top cover. The amp has some minor scuffs and scratches that don't even come up in the pictures. The sub's speaker cover shows wear. 

I would prefer local pick up and am willing to meet halfway, but can ship anywhere in the US at buyer cost.
