GROUND ZERO GZNK 165SQ-K 165 mm / 6.5″ SQ midwoofer SQ

Equipped with many of the special features of the high-end PLUTONIUM line, GROUND ZERO still managed to position the products of the NUCLEAR line at an attractive price level. Nevertheless, the amazingly sounding speakers are partly “Made in Germany”. The subwoofers are suitable for high-performance audio setups as well as SPL competition. The solidly built and equally impressive sounding mono amplifiers deliver outstanding top performance.

In order to put together an individual sound quality setup, the speakers in the NUCLEAR line are available as components in pairs.
