Installation of the GTO620 and GTO630 as shown in Figures 4a, 4b,
4c and 4d. The GTO620 and GTO630 use JBL’s patented Intermount II™
mounting system. Intermount II provides for easy installation of these
speakers in many standard and nonstandard locations
that will accommodate a 6-1/2" speaker.
Important: When using the steel mounting rings, you
must use the sheet metal screws with undersized heads
that are included in the hardware pack and make sure
that the ring is mounted to a completely flat surface.
