The Ground Zero GZRC 165.2SQX-IV from the RADIOACTIVE series was developed for discerning music lovers who value exceptionally precise and natural sound reproduction. The high-quality 165-mm SQ low-midrange driver with a black aluminum cone delivers clean midrange reproduction, controlled bass, and high dynamics. The system is complemented by a vented 25-mm silk dome tweeter that reproduces finely detailed highs without harshness.

Thanks to its efficient 3-ohm design, this speaker system is suitable for both high-powered factory radios and external amplifiers. Separate high-pass and low-pass filters ensure clean frequency separation and enable balanced sound tuning with high detail reproduction—ideal for high-quality audio systems.
