Steinway & Sons

LS Concert


The LS series is the number one choice for larger rooms and spaces with rows of elevated seats. The series features an innovative line source approach incorporating floor-to-ceiling stackable speakers and boundary woofers. This allows sound to propagate over long distances, thus ensuring tonal consistency by reducing echoes, especially in large rooms. Line source technology means that every seat in the listening space has the same volume level and offers the same sound experience, from the front to the rear of the room.

Floor-standing speakers

The in-room LS speakers blend the dipole technology first introduced in the flagship Model D with the innovative line source technology from the LS. At over 8 and 6.5 feet tall, the open baffle LS speakers are for very large rooms where a sound system must sound – and look – impressive. The series consists of two full range floor-standing dipole speakers, the LS Concert and LS Studio, which emit sound from both front and back.

Integrated system approach

All Steinway & Sons products can be combined for individual Steinway & Sons sound systems and follow our integrated system approach. The chosen loudspeakers are programmed into the processor, and amplifiers are connected reliably using our own digital signal connection. RoomPerfect™ will further acoustically calibrate the loudspeakers to the room. With this integrated system approach, we can guarantee the legacy of absolute perfection that comes with the Steinway & Sons partnership. A perfection which can never be attained mixing products “off the shelf” from different manufacturers.

This loudspeaker can be combined with the following models, depending on the room and customer wishes.
