Who is Black Diamond Racing?
"BDR" was founded by DJ Casser to explore the application of advanced composite materials, such as carbon fiber, to alternate structures. Familiarity with these types of materials was first achieved during 30 years of Yacht racing. In this field, maximum performance, virtually regardless of cost, is the goal and measured to hundredths of a knot!  Combined with DJ's passion for audio spanning over 20 years, blending the two seemed a logical choice. What transpired was an R & D effort costing 20,000 hours and a literal fortune.

What was discovered?
It was found that vibration has a far more significant effect on audio than most people realized. BDR's research and testing, including evaluation by some of the best equipment and ears in the world, indicated it was a combination of high rigidity along with high damping rates, that provided by far the best results. As carbon fiber has five times the tensile strength of steel, they found it to be the best material for optimal performance available at this time. What you find here is just a sampling of the BDR product line. Please call or email us with your questions.
