Easy to install 165 mm / 6.5” speaker system – GZRC 165AL-IV


With the introduction of the brand new RADIOACTIVE series GZRC 165AL-IV Ground Zero starts with a full line of easy-to-install speaker systems on the basis of the well known GZRC 165AL.


The upcoming models will be identified by the ending “IV” in the product name indicating the installer version. Each of these systems will contain a pair of slant tweeter housings in black rubber finish as well as separated crossovers for high and low pass signal simplifying the installation significantly.


The 25 mm / 1” GZRT 25T tweeter with black machined aluminum housing and titanium dome is responsible for the high frequency range while the matching midwoofer GZRK 16AL with an aluminum cone handles the lower signal section featuring a high efficient 3 Ohm copper voice coil with a diameter of 25 mm / 1”. The crossovers of the system capable of handling up to 120 Watts of RMS power include high quality MOX resistors, MET and Elko capacitors as well as a PTC element to protect the tweeter from damage and offer a three-stage tweeter level adjustment.
