Enhancing Loudspeaker Efficiency and Bl(x) Symmetry with Virtual Voice Coil, Part 2

This is the second article detailing the design and simulation possibilities of the SpeakerLAB software and its Virtual Voice Coil (VVC) module for speaker designers. This simulation includes complete temperature management involved in loudspeaker calculus. The article also expands on audio transducer parameter prediction such as maximum SPL, analyzes key design components such as the magnetic circuit, and analyses the resulting simulated metrics that could help determine the highest efficiency.
