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:
| Depth | Height | Width | |
|---|---|---|---|
| BW-20 | 95 mm / 3.7 in | 585 mm / 23 in | 290 mm / 11.4 in |
Cables
- Recommended minimum up to 8m / 50ft : AWG 14/2 or 2-lead 2mm2
- Recommended minimum from 8m / 50ft and up : AWG 11/2 or 2-lead 4mm2
- Recommended maximum : AWG 10/2 or 2-lead 5mm2
INSTALLATION
Connect the Loudspeaker Cable
Remove the supplied Neutrik speakON cable connector inserted at the BW-20
cable port (underside).
Attach and tighten a speaker cable to the speakON cable connector. The Neutrik speakON connector allows a wire diameter between 1.5 – 4 mm² / 16 – 12 AWG, to be screwed or soldered. On the cable’s amplifier end, any connector type can be used
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
Lyngdorf Audio BW-20 Installation manual 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..
