electronic loudspeaker

It is widely accepted that the loud- . speaker is the weakest link in the high-quality audio chain. This is particularly the case at the lowest working frequencies due to the difficulty of providing a useful air- load for a radiating diaphragm that has dimensions small compared to the sound wavelength. This compels the manufacturer to adopt clever but more or less expensive constructions for the loudspeaker unit and its enclosure. The manufacturer has the resources and facilities to tackle the problems at the mechanical-acoustical stage. This article explains that the do-it-yourself approach that provides the best results at the lowest price is invariably the "electronic loudspeaker".
