Ground Mount Without Security Plate
If you choose to mount the SAT300
loudspeaker in the ground without the
security plate, be sure the ground is
compact enough to hold the speaker and
stake securely in the ground. Gently drive
the ground stake into the ground using a
rubber mallet and follow instructions from
step 4.
