Ground Zero GZRC 165.3SQ-ACT
Ground Zero's Radioactive SQ series is new for autumn 2019. The series' goal has been to provide the best possible sound quality in its price range. The design has taken advantage of Klippel optimization, which allows the speaker element structure to be refined to the last detail.
The collection is based on the previous Radioactive AL collection, in the design of which Ground Zero's Finnish importer Audioimport (now AI Group) has been heavily involved. The elements work excellently in typical car installation locations. The midbass works better in door installation instead of enclosure without building separate enclosures.
The mid-woofer has an aluminum cone and rubber suspension. The lower-than-normal 3 ohm impedance helps extract more power from your instrument or amplifier. The mid-woofer has a neodymium magnet and a composite cast body. Thanks to these, the installation depth and magnet size are suitable for most cars. The tweeter has a silk dome tweeter. Speaker grilles are included in the package.
Also available as a 2-way separate set Ground Zero GZRC 165.2SQ and a passive 3-way separate set Ground Zero GZRC 165.3SQ. Separate tweeters Ground Zero GZRT 25SQ, midrange drivers Ground Zero GZRM 80SQ and midbasses Ground Zero GZRK 165SQ complete the range.
