Use NHT's super-powerful, super-clean SA-3 to drive your passive subwoofer or the built-in subs in your biampable main speakers, and get ready for soul-stirring, audiophile-quality bass!

This versatile amp has plenty of power in reserve to push both of the bass drivers in a biampable stereo pair. Or use 2 SA-3s for even more impressive bass, and stereo subwoofer performance. The SA-3 is a perfect solution for biamping NHT's VT-2.4 Home Theater Series or 2.9 Music Series towers.
