3.5 Orientation
It’s strongly suggested to place the uniK plus vertically. Do not place them horizontally.
3.6 Additional Comments
Please also make sure to not place any obstacles that may block the flow of air or that could
generate sound reflections (especially highly reflective material including glass or metal) in front of
the monitor. Also, don’t put plants in pots on top or too close to your monitors.
If possible, avoid placing the speakers into the corner of a room as this may cause reflections from
both sides, which may alter the sound. It is best to place them with a 90° or 0° angle in reference to
the closest wall. If this cannot be avoided, it might be advisable to close the vent port with the
included ESI Bass Port Plug
TM (see below under 3.7).
3.7 ESI Bass Port Plug
TM
for vent port
uniK plus has a vent port that is conveniently placed on the backside of the unit, making sure that
air does not get blown into your face when you listen in a near field situation and to make sure that
parasitic frequencies from the inside of the cabinet are sent out through the rear. When uniK plus is
placed too close to the wall or especially when placed angled in a room corner, low frequencies
could get emphasized a bit too much. As vented speaker systems have this issue more than closed
speakers, it can be better to have a closed speaker system when they are used in small rooms, in
corners or very close to a wall – while when placed into a larger room, obviously the open system
with the vent port is better.
Because of this, ESI developed a truly unique feature: uniK plus are shipped with an ESI Bass Port
Plug
TM . This plug made from a special acoustic material allows you to turn uniK plus either in a
completely closed system (ESI Bass Port Plug TM inserted into the vent port) or a regular open bass
reflex system (vent port is open):
