(requiere suscripción). «The key difference in the Rice and Kellogg design was the adjustment of mechanical parameters so that the fundamental resonance of the moving system took place at a lower frequency than that at which the cone’s radiation impedance had become uniform. Over this range, the motion of the cone was mass controlled, and the cone looked into a rising radiation impedance. This in effect provided a significant frequency region of flat power response for the design.»

Consultado el 29 de diciembre de 2009. «The D2 is unlike traditional speaker technology because it uses a very high powered magnetostrictive smart material as the driver instead of a moving coil. The material was originally developed by the US military for sonar applications and is now de-restricted for commercial use.»

Consultado el 5 de octubre de 2009. «The cone-shaped speaker system is 95 mm in diameter and 90 mm high. It features an actuator using a magnetostrictor that extends and shrinks in line with magnetic field changes. The actuator converts input sound into the vibration and conveys it to the tabletop thus rendering sound.»
