Step 3Locate Spikey Feet and Add Weights
iImage Information

The spikey feet come in a set of 4, 2 for each speaker. They require a 3/8" drilled hole. Note the feet and internal hardware must clear the back of the installed speaker driver unit. The feet are mounted 60 degrees apart. Measure the circumference of the cylinder with a tape measure, divide by six, and measure and mark half of the result on each side of the centerline (the container label has a centerline). I ultimately mounted the feet with the nubby ends facing out, to minimize surface scratches. Due to the weight of the driver units, the speakers are front heavy and flop forward. To counteract this, I added 4 lead fishing weights in a duct tape "package" taped to the back of the speaker.
