Room placement is flexible; however, for best bass performance place
your Core Sub close to a wall or in a corner, leaving 3˝ to 4˝ (5 cm – 8
cm) of space between the Subwoofer and the wall (as shown below).
Bass is a personal preference, so we encourage you to experiment to
find the placement that best suits your listening tastes.

separate Subwoofer pairings within the same house.
Example of a Multi-Room Network
If you have a TV in the family room and another one in the living room,
or a bedroom, or basement, you simply select different channels for
each pairing so that all groups (speaker and subwoofer) operate
independently and without interfering with each other.
You can have up to 4 separate Core speaker and subwoofer pairings
throughout your home, with each Core speaker playing with its own
Core Sub.

as a pair on the network:
On your Core speaker (powered on}: Press and hold the
POWER l0 and VOLUMEG keys for 5 seconds.
The top LED will flash green, once, confirming pairing
with your Sub.
3. Press the MULTI-ROOM key cJ on the Core speaker.
Your Core speaker will now always remember the Sub it is
paired with, even after powering off.
To unpair the Sub from your Core speaker, press and hold
the POWER l0 and VOLUME 8 keys, on your Core speaker,
for 5 seconds or until
the top LED flashes red once.

functionalities. Once
the Sub is wired, its LED indicator will turn to
white {line-in}.
