Rubber Feet & Adjustable Floor Spikes

Rubber feet and adjustable floor spikes are included  
with your LSiM floorstanding loudspeakers to anchor  
and stabilize the speaker on any type of floor. However,  
you may wish to tilt the speaker backwards or forward  
a tiny bit in order to optimize your listening area. This  
is a subtle change you can experience that optimizes  
imaging in your setup.

To Adjust The Floor Spikes

The floor spikes can be adjusted with the use of the  
supplied 5 mm hex (Allen) wrench. Most floorstanding 
speakers are adjustable only from below and require  
two hands. The LSiM floor spikes are adjustable  
from above.

Note:

 If the speaker is stable on the floor, no adjustment  

is necessary.

If the speaker is unstable, follow these steps:

1.

 

The speaker will be inclined to settle on three of the  

  four spikes leaving one spike slightly off the floor.

2. 

Determine which spike needs to be adjusted.

3.

 

Use the supplied hex wrench and turn it clockwise  

  to lower the spike or counterclockwise to raise it. 

4. 

The threaded portion of the spike is coated with  

  a locking compound, so the spike may offer some  
  resistance when you turn it.

5.

 As the spike contacts the floor, it will become  

  more difficult to turn. At that point the speaker  
  should be stabilized.
