PRE-INSTALLATION
Unpacking the BW-20

provider for repair; therefore, it is recommended that you save your original packing materials. If this unit is

Finding the right placement for the BW-20
The BW-20 is designed as a Boundary Woofer. For the best performance the recommend placement is as close
as possible to boundaries, for example in a room corner or close to the wall. The best placement is inside a
wall cavity with the BW-20 woofers front-firing, in-line with the in-wall speakers. If the BW-20 is placed in the
room, the best placement is with the woofers back-firing, facing the boundary. The BW-20 can also be placed
with the woofers front-firing into the room.

Required space for the BW-20 in the room
If the BW-20 is placed back-firing to a wall, leave a minimum of 50 mm / 2 inch to the wall to allow for the
woofer excursion and soundwaves to emit.
If the BW-20 is placed front-firing into the room, place it as close as possible to the wall. Leave a minimum of
10 mm / 0.4 inch space to the wall so the BW-20 is not making contact, in order to avoid mechanical
resonance. Leave an extra 30 mm / 1.2 inch space in front of the BW-20’s own cabinet to allow for the woofer
excursion.
Required space for the BW-20 in-wall
If the BW-20 is placed front-firing in a wall opening, the minimum space required including mounting feet is:

INSTALLATION
Connect the Loudspeaker Cable
Remove the supplied speakON cable connector inserted at the BW-20 cable port.
Attach and tighten a speaker cable to the speakON cable connector. Make sure the cable ends are securely
tightened and no bare wire is standing out. Plug-in and turn the speakON connector back to the BW-20
speakON connector port.
Place the BW-20
Bring the BW-20 to its upright position in the selected location. Once upright, adjust the four spike feet to
level the BW-20 and achieve optimal stability.
Using the feet of the BW-20
You can either use the attached black floor protectors over the spikes to prevent scratches on the floor, or use
the spike tips to make a firm, almost fixed contact to the ground. Be careful with the spike tips to prevent
damages or injuries.
