What makes DIYMA different from so many other car audio forums and information sites is not only our DIY approach to mobile audio accuracy, but the testing methods and research we conduct for our community. We own several pieces of equipment that we use to test the accuracy and distortion levels of various loudspeakers. The most valuable data we collect is from our Klippel unit which is used for the measurement of the mechanical vibration and the geometry data of cones, diaphragms, panels, and enclosures.

These tests are done by Neil Middlemiss and are published on our website and discussed in our community forum. This is information you will not be able to find from any other 12 volt website or forum and truly makes DIYMA stand out from the crowd. In many cases, after we test the drivers, speakers or subwoofers we give them away to members of our forum, where they are then reviewed again, but the winning participant.
