USIng the SUPPlIed SPIkeS

Four metal spikes are supplied for use when you place the subwoofer on a
carpeted surface. Using the spikes decouples the subwoofer from the oor
and prevents unwanted acoustic damping.

TO INSERT THE SPIKES:

Gently turn the subwoofer upside down on a soft, nonabrasive surface.1.

Unscrew and remove the rubber bumpers from the subwoofer’s feet.2.

Screw each spike into the threaded insert in each foot. Make sure all 3.
four spikes are screwed in completely for stability.

NOTE: NEVER drag the subwoofer to move it, as this will damage the
spikes, the feet and/or the subwoofer cabinet itself. Always lift the sub­woofer and carry it to its new location.
