• BW-20
• 4 x mounting feet with spike / floor protector
• 1 x Neutrik speakON cable connector

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:

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..
