About OSD

OSD started in 2003 with a small line of outdoor rock speakers sold direct, and grew into a full custom-installation catalogue - landscape satellites, in-ceiling, in-wall, distribution amplifiers - on the same argument: cut the distribution layers and the same product costs less.

Notable models: AP series outdoor speakers, Nero amplifiers, landscape satellite kits.
