Model S-15


The Model S series has been installed in hundreds of high performance home cinemas and living rooms all over the world. It is petite and so discreet it can be installed without compromising décor, but don´t let the size fool you. The Model S-15 is an incredibly powerful speaker recognized with numerous awards and accolades, making it the clear choice for those seeking perfection at a competitive price point.

Logic-defying performance

The performance of the petite Model S is nothing short of extraordinary. The reason is partly due to the innovative design of the Steinway & Sons Model S-15 speaker. Because the Model S-15 relegates bass duties to boundary woofers, it reproduces only high and midrange frequencies, and it does both with incredible volume capabilities and zero distortion. Its legendary performance makes it a perfect match for medium-sized high-performance home theaters.

Ambience enhancing radiation

A key feature of the Model S-15 speaker is its innovative AER (Ambience Enhancing Radiation) dipole tweeter design. This design disperses the highest frequencies, which produces a spacious and live effect throughout the listening room, similar to the effect you get from our flagship Model D speaker or a live instrument.

The smallest of the grands

The Steinway & Sons Model S speaker is named after the smallest of the Steinway grands, the Steinway and Sons Model S piano. This design was introduced in the 1930s to invite the majesty of the Steinway sound into almost any space.
