High Density Phinolic Resin
High Density Phinolic Resin (HDPR) Fiber-Board The use of various materials have been disputed and advocated for years in the audio industry. Through our testing, we have found the following to be true; Fiber and layer compositions are better than solid woods (soft and hard). But this is were the real arguing begins, there are many who prefer birch ply, and others proponents of fiber. After testing we chose to begin working with fiber compositions as we could then manipulate additives, density, fiber mixes, etc. We finally acquired the right formula that gave a very “dead” response and had very low resonance properties.
