7.1 NHT Speaker System with Acoustic Research S 112 PS Subwoofer & Subwoofer Cable. From a non-smoking, no pet household. Speakers are in excellent condition, some near-mint or better. The Acoustic Research Subwoofer, also circa’98-’99 was among the most sought after among audiophiles. My Pioneer Elite receiver is from 1997, and may sound a bit dated, but the speakers are stellar! 2 X NHT Super Zero. 5 X NHT Super One 1X NHT Center Channel Speaker 1X Acoustic Research S 112 PS. 1X Subwoofer Subwoofer Cable.
