803 Diamond
A Legend Reborn
The 803 Diamond might look almost as imposing as the 802 Diamond, but thanks to its smaller footprint and more traditional cabinet design, it will fit more easily into a home environment. With three Rohacell 7” bass drivers it delivers almost as much bass as the 802 Diamond, filling even the largest of domestic rooms with rich, lifelike sound.
