Lyngdorf Audio BW-20
BW stands for Boundary woofer – a Lyngdorf approach where a subwoofer is designed to be placed near the wall boundaries, for example right in the corner, achieving the best bass impulse response by avoiding delayed bass bouncing back off the walls, instead taking advantage of room acoustics. The BW-20 is the company’s largest BW model, extending the line-up of the compact in-room woofers BW-2 and BW-3.
More than a subwoofer
The BW-20 is a high-bandwidth woofer, reaching down to 19Hz but also up to 500Hz. This allows a seamless integration with any size front speakers and crossover filter type, and avoids any sound performance gap even if the front speakers are not low-reaching full-range speakers.
In-wall, on-wall, in-room
The overall construction with both woofers on one side, closed-cabinet design, shallow cabinet depth and satin-matte finish allow both in-wall and in-room placement. The best performance and speaker integration will be achieved as an in-wall woofer together with in-wall speakers, while the cabinet design also allows placement in the room, used as a free-standing boundary woofer firing into the room or against the wall.
High-performance boundary woofers
BW stands for Boundary woofer – a Lyngdorf approach where a subwoofer is designed to be placed near the wall boundaries to achieve the best bass response. A boundary woofer avoids reflected bass bouncing off the back wall and side walls, instead taking advantage of room acoustics.
Two high-performance 12” woofers are equipped with large vented magnets, double spiders, and aluminum cones. The high-excursion design allows an excursion of +/- 20mm and enables the BW-20 to play the lowest frequencies at a very high volume level.

Bass
90/100
Two 12" long-throw drivers in a 64 L closed cabinet with stated -3 dB down to 19 Hz (EQ dependent) and 118 dB SPL capability point to very strong extension, control and output for a sealed design. Score based on specifications in absence of reviewer measurements.
Dynamics
88/100
Long-throw drivers, 67 mm voice coils, double spiders and 700 W IEC handling plus 118 dB max SPL indicate strong transient headroom and slam potential. Score inferred from driver and power specs rather than listening reports.

Integration
72/100
Passive boundary woofer design and speakON connections suggest placement and amp-matching flexibility, but there is no reviewer outcome evidence about blending with mains. Features ≠ Integration; add outcome evidence or lower Integration.

35 kg MDF cabinet, aluminum cones, double spider and vented magnet motor suggest robust driver and cabinet construction; matte-black finish and Neutrik speakON imply professional-grade build.

Value for Money
72/100
At ~€4,196 (single-unit price provided) the BW-20 is expensive; the price can be justified by build and spec, but no review language asserts exceptional value vs peers, so value score is conservative.
