The Signature Elite ES55 is a floor-standing loudspeaker with three drivers, the largest measuring 6.5 inches. It is Hi-Res Audio Certified and is intended for movies, music and gaming, with the aim of filling a room with wide, cinematic sound and strong low-frequency output.

The design combines a Dynamically Balanced acoustic array with precision crossovers, and uses Power Port technology to enhance bass response. These elements are described as working together to give an even tonal balance across the range.

The speaker is listed for medium and large rooms and belongs to the Signature Elite series, which sits alongside the ES50 and ES60 towers. It is offered in black, white and brown finishes, and in new or refurbished condition. Connection details such as terminals and impedance are not given.
