This allows the speaker to respond quickly to audio signals, making it suitable for both dynamic bass reproduction and detailed midrange performance. With a usable frequency range of 40 Hz to 5 kHz, the GZNK 165SQ-K can be flexibly used in high-quality 2-way or 3-way active systems\u003c\/strong\u003e\u003c\/span\u003e.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eFor the driver, Ground Zero relies on a neodymium-ferrite hybrid system. This is complemented by a 38-mm CCA voice coil and a copper cap to linearize the impedance.
