Definitive’s Disappearing™ series feature near invisibility. This is due to their small diameter, hidden flange design and low profile grilles. Installation of the DI 5.5BPS is incredibly straight forward and just as simple as any traditional wall speaker.

The bipolar sound dispersion is ideal for rear or side sound dispersion, or anywhere extremely broad sound dispersion is desired. These speakers also feature some of Definitive’s most advanced technologies such as pivoting tweeters for spectacular audio performance. Thanks to these technologies this speaker also offers the bass output and dynamic range of a larger driver.

The DI 5.5BPS have been designed to disperse sound over a wide area, whilst maintaining a natural and well-balanced sound. Furthermore, the adjustable tweeter means that the DI 5.5BPS can be aimed to a specific position.

Overall this speaker offers great audio performance and looks sleeker than traditional ceiling speakers.
