Mechanical and Acoustic Power,mechanical-plus-acoustical power. Next are offered acoustic power relations to kinetic-energy effects, followed by the distribution of energy and power over the driver’s operational AC cycle. Calculations of power losses and key driver parameters, including overall efficiencies as a function of driv

Related Parameters and Measurements,plitude. From these, the SPL (sound-pressure level) is calculated. Next, a significant analysis of the . (motor) parameter is detailed and related to the back-EMF. A careful first-principles lab measurement of the . force is then offered, along with a detailed technique required for accurate results

Circumventing Efficiency and Bass Extension Limitations,ch gained commercial fame in the 1970s and 1980s in multiple audiophile speaker systems produced both by the Watkins firm and also by Infinity Systems of Chatsworth, CA. The revolutionary technique was granted U.S. Patent 3838216 in 1974 and was further documented in a landmark article by the same n
