Boundary woofers

For the optimal coupling to the room

The basic principles underlying Steinway Lyngdorf boundary woofers demanded a fundamental re-thinking of the overall concept of high fidelity bass reproduction. Conventional subwoofers are designed to generate maximum output below 100 Hz. To do so, they typically incorporate very big drive units in large enclosures that are incompatible with convenient, room-friendly installation.

Steinway Lyngdorf developed innovative boundary woofers more than twenty years ago for use in the finest music systems where speed and musical timing are main priorities. The drive units are designed to start and stop as quickly as possible. Generating massive bass output is not really hard work, the true challenge lies in making it precise and tight – not boomy.

Steinway Lyngdorf’s self-powered, high bandwidth boundary woofers focus on dynamics and precision, with seamless integration in any contemporary interior. Based on specially designed, long-throw bass drivers, featuring a massive magnet, voice coil and cone assembly for vertical or horizontal placement close to floor and walls, the compact system reduces cabinet resonances and allows optimal coupling to the room. For the ultimate transformation, we recommend a pair of boundary woofers, ideally placed in the front corners of the room and calibrated with RoomPerfect™. This takes full advantage of their extended bandwidth, for bass that blends seamlessly all the way up to 800 Hz.

In a Steinway Lyngdorf system employing boundary woofers, you will experience a quality of bass as never heard before from regular subs or speakers.

Woofer placement

To take maximum advantage of their capabilities, place the Boundary woofers in the corner and on the floor. Results in increased efficiency and reduction of reflections.

Boundary woofer recommended placement options:

Layout of boundary woofers with side-mounted drivers (minimum distance from the woofer to the front and side walls = 4 cm)

Side-firing in-room woofers

Layout of boundary woofers with rear-mounted drivers (minimum distance from the woofer to the front and side walls = 4 cm)

Rear-firing woofers

In-wall woofers

(Sub)woofers can be positioned in the corners of the room – this position will offer better time-response (tighter bass) as well as improving the overall output with more than 6dB. RoomPerfect™ will subsequently integrate the subwoofer(s) with each speaker in order to have a perfect performance from each channel.
