Using damping feet
The damping feet are suitable for hardwood, tile and multilayered floors. The damping
properties of the material reduce vibrations which can propagate through the floor. The
four damping feet included per loudspeaker should be affixed securely, and will balance
any slight surface unevenness without scratching the floor.
Mounting the damping feet:
1. Bring loudspeaker to its assumed position and place it carefully on its back.
2. Screw in the damping feet (four per loudspeaker) using a hexagon socket screw
wrench and tighten each properly.

Distance to back and side walls

Every loudspeaker not only disperses sound energy directly into the room, but also to the
side and even backwards. As a result, time-delayed reflections occur and add to the
original music signal. Thus, when loudspeakers are positioned too close to walls, the
sound quality can be restricted.
The Sapphire loudspeaker was developed to be placed free-standing, and therefore it
reaches its optimum performance when positioned as clear of any walls as possible.
To reduce possible influences from the back and sidewalls, the distance to these
boundaries should ideally not be less than 0.5 meter.

Adapting the bass reflex port

To minimize low frequency reflections, which will be heard as a thickening of the sound,
the loudspeakers can be adapted to the room's acoustic character by using foam plugs in
the bass reflex port. This will essentially attenuate the room-induced boost in the low
frequency range by dampening the deep frequencies, yielding a more clear and tight
sound and minimized backwave reflections when the loudspeaker is positioned near rear
walls.
Fully insert the foam port plugs packed with your loudspeaker into the bass reflex tube,
to attenuate the bass output (if required).
