Description

The BW-3 is designed as a high bandwidth subwoofer with the objective of reproducing optimal dynamics and precision. This is reflected in the frequency range of the driver reaching up to 800 Hz in bypass mode, in contrast to traditional subwoofers, which are typically limited to 120 Hz.

Powerful and compact design

The internal amplifier is Lyngdorf Audio’s Class-D design based on more than 15 years of experience in designing audiophile Class-D amplifiers. With an output of 400 watts, it can deliver ample power to control the powerful 8” driver – even at high levels. The BW-3 is equipped with a long-throw driver mounted in an extremely compact enclosure. For the driver to work in such a compact cabinet, with only 7 l of internal volume, a custom unit was designed. The 8” woofer features a massive “motor,” which has an extremely fast response and high efficiency.

Flexibility in installation

The woofer fits into all types of setups, as the amplifier module holds the traditional signal controls as well as a bypass switch for easy and direct connection to Lyngdorf Audio amplifier outputs or to other audio products, which provides full control of the sub-out connection.

The BW-3 is delivered without feet mounted, as the compact cabinet design allows for several ways to integrate the speaker with home décor. With cabinet dimensions reduced to a minimum, the BW-3 can be positioned standing upright or on its side in order to fit into the available space. This construction makes it the perfect match for any setup, as a subwoofer for other speakers in a stereo or home cinema system.
