The BW-20 stands as a formidable passive subwoofer, perfectly complementing the most advanced Lyngdorf stereo and surround setups. Designed primarily for in-wall installation, it emerges as the premier choice for those opting for a Lyngdorf in-wall configuration, aligning seamlessly with LS or D series installation speakers.

Its unique design, featuring woofers positioned on one side and a compact depth, coupled with a satin matte finish, allows for versatile placement options. While it excels as an in-wall subwoofer paired with similar speakers, its design also supports its use as an independent boundary woofer, projecting sound into the room or against a wall.

Equipped with two 12″ long-throw bass units featuring ventilated magnet systems, dual “spiders”, and robust aluminum diaphragms within a 64-liter, reinforced cabinet, the BW-20 effortlessly handles deep bass at high volumes in expansive areas.

As a passive unit lacking an in-built amplifier, it empowers you to select an amplifier that suits your preferences and system needs. This flexibility extends to adjustments available on the main unit, eliminating the need to adjust settings from the floor, as is common with traditional subwoofers.

The acronym BW represents a boundary woofer, designed for wall-adjacent or corner placement to optimize bass impulse response. Such positioning minimizes sound reflection delays, enhancing the original audio signal’s clarity.

Positioning close to walls, especially corners, leverages the room’s natural acoustics to amplify bass, potentially adding up to 9 dB of dynamic range. This effect can mimic the output of a significantly more powerful amplifier.

While this placement might typically result in overwhelming bass, Lyngdorf’s RoomPerfect digital room correction system manages this effortlessly, allowing optimal use of boundary woofers without acoustic issues. This setup encourages choosing a compatible power stage that best fits your preferences.

Perfect with compact speakers

The BW-20 uniquely covers frequencies up to 500 Hz, supporting both small and large front speakers well into the midrange. This capability makes it more adaptable than standard subwoofers.

For systems with small satellite speakers and a high crossover frequency, deploying two BW-20 units is advisable for accurate sound staging. Lyngdorf amplifiers and processors, integrated with RoomPerfect, are designed for such arrangements, ensuring optimal performance from your BW-20 setup.

Pros

  • Extremely deep, dynamic and precise bass for both home cinema and music
  • 2 x 12” purpose-built long-throw elements
  • Plays perfectly with both large and small speakers (goes all the way up to 500 Hz)
  • Can be hidden in a specially built wall or used freestanding
  • Can be advantageously placed right next to the wall or in a corner
  • Effortlessly matches sound systems right up to the extreme high-end class

Cons

  • Works best in Lyngdorf systems with RoomPerfect
  • Passive construction – needs a separate power stage with associated cables
  • Designed for maximum sound quality – not to be visually exciting
  • Demands its place
  • For “in-wall” installation, the wall must be specially built to the cabinet depth of 27 cm
  • No dedicated front grill
