Audiophile-Grade Wireless Speaker
  • The W9 is Definitive Technology’s flagship audiophile-grade wireless speaker. Created for audio aficionados with unrelenting performance expectations, the W9 delivers exceptional dynamic range and extraordinary bass response. Transducers on the front baffle and on both sides of the enclosure create a “Tri-Polar” dispersion pattern that radiates sound off of the surrounding walls.
What Obsession Sounds Like
  • There’s a fine line between loving music and being obsessed with it. When it comes to making music sound the best it can sound, we have a hard time believing that good enough is acceptable. It has to be flawless. Perfect. Uncompromising. In short, we think it would be crazy to give music anything less than everything it deserves.
Definitive Technology Apps
  • The free Definitive Technology App allows you to mix-and-match speakers with the open PlayFi™ Technology standard and future-proof your home music solution. The Definitive Technology Utility App provides extended functionality, including product firmware updates, source selection (if applicable) and EQ settings for the W Amp.
