Speaker Stands
Some speaker stands are hollow and have access holes that can be used to
fill in with sand, lead shot, or some other heavy material. These filler
material make the speaker stands more stable (because the center of
gravity will be close to the floor) and offer solid reference to the
mechanical moving parts of the speakers, thus provide better vibration
isolation and damping effect. In this general results in overall improved the
sonic performance over the speaker's dynamic range.
Speaker Stands with height ranging from 18
＂ - 26 ＂ is recommended, you
should note that the optimum stand height is the one that places your ears/
seating height approximately 1
＂
above the top edge of speaker.
Many speaker owners use adhesive material; such as, Blu-Tack (Bostik
Brand) / Sticky-Tack to attach the bottom of the speakers to the top of the
stands. This reduces the chances of the speakers being accidentally knocked
off the stands thus damaging the speakers. If adhesive is used, place a
small piece of adhesive under each corner of the speaker where it makes
contact with the speaker platform.
Caution: Removing speaker from the speaker stand or removing adhesive
from the speaker may cause damage to the surface of the speaker. Do so
with great care.
Speaker Placement
The JAS Orsa speakers can produce excellent sound in any location.
Therefore you should use these guidelines as a starting point and make
minor adjustments to the position of the speakers and other objects in the
room until you find the combinations that sounds best to you.
As a general rule, the distance between the front plane of the speakers and
the front wall of your listening room should be approximately 20% of the
total length of the room; the distance from each speaker to the closest side
wall should be about 20% of the total width of the room. The distance from
the listener＇s chair or couch to the wall behind the listener should be about
the same as the distance between the speakers and the front wall.
