Overview & Specifications
The Signature 903 offers all the qualities of the 900 series in a compact format. It is therefore predestined for use in smaller rooms, where there isn’t much space or as a surround-sound add-on for home cinema applications. The Hi-Res Audio-certified tweeter module is used here together with a 170 mm woofer featuring a ceramic-aluminum diaphragm. It shares the exquisite black piano lacquer or Macassar veneer finish with the other models in the range.
