Wisdom Audio spikes are reversible for use on either hard or carpeted floors.
The sharp end of the spike is designed to penetrate the carpeting and couple
to the floor beneath, for excellent stability and improved sound. When on tile
or hardwood floors, however, use the blunt end of the spike instead to avoid
floor damage. In either case, you can adjust the height of the individual spikes
to compensate for slightly uneven floors. When this fine adjustment has been
made, tighten the large black nut snugly against the bottom of the base to pre-
vent them from further movement.
Note: If you fail to tighten the black nuts that secure the spikes, they may
rattle a bit when playing music or movies. This rattling can sound
like speaker distortion. Fortunately, a quick tightening of the lock
nuts on the spikes will eliminate the problem.
After you have determined the final locations of the L75 speakers, enlist the
assistance of a friend to safely tip the speaker to provide better access to the
adjustable spikes to maximize stability (even with uneven floors). Tilting it even
as little as 15°-20° provides access to the threaded holes for the spikes without
straining your helper. Reverse the spikes if you are on a carpeted floor. Once the
first two spikes are securely in place, switch sides and repeat the process on the
other side. Fine-tune things until the speaker is both solidly stable and plumb.
