803 D3 Speaker

True sound comes home

The 803 D3 is the first of its kind: a full-range, studio-quality speaker built for the home, and the most compact headed unit we’ve ever produced. While this elegant speaker comes in a living room-friendly size, it shares the same revolutionary technologies and design features as its larger siblings, including our turbine head and reverse-wrap cabinet.
