Why have the basic laws of electrodynamics been ignored in the design of all loudspeaker operations? A frank exposure of the flaws of voltage drive and a thorough, groundbreaking guide to the only physically justified way of operating electrodynamic loudspeakers - current-drive. The author argues that the sound quality of virtually all existing speaker systems has been severely impaired by the manifoldly indefinite electromotive forces induced in the voice coil, that corrupt the flow of current; and what's dramatic - the measurable evidence is plain and overwhelming! These inherent EMFs in themselves can never be suppressed by any kind of amplifier, but their detrimental effect on current and hence on sonic performance can be eliminated by adequate source impedance. Thus, the secret of valve amplifiers also becomes apparent. Written for all from the academic community to lay hobbyists. Besides new concepts for amplifier and speaker design and demonstrative projects, the book also features novel ideas for modelling, filter design, measurements, and protection; and a useful tutorial on analogue linear systems.
