There is a small 8x6 mechanical room in one corner of the space so the shortest of the longer walls is approximately 32 feet.
Mounting speakers in corner of wall.
I intend to mount the speakers on this 32 foot wall but could mount one on the mechanical room wall so that one would be on the base and one on the leg of the l shape created by the connecting walls.
Ideal speaker placement for the front left and right speakers is 6 to 10 feet apart and positioned at seated ear level.
These anchors require 5 16 inch holes.
To help you decide how far to put the speakers from your wall use one of the three options given in this guide.
Try to locate the speakers at least 3 feet from a corner to avoid boomy bass from boundary effects.

When mounting the speaker bracket to drywall or paneling use toggler tb hollow wall anchors also included in the panavise hardware kit.
Odds are that the left and right will straddle a flat panel or screen and the center will go in just below or sometimes above.
