DESCRIPTION:Loudspeakers are fundamental to maintaining the fidelity of sou
 nd in radios\, TV\, and theater\, and aficionados have debated the reprodu
 ction quality of different types of loudspeakers and their associated elec
 tronics for decades. The goal of the early loudspeakers was to modify and 
 suppress acoustic radiation from the rear of the speaker-driver. Further w
 ork on such speakers concentrated on materials that could suppress selecti
 ve radiation from the rear diaphragm. However\, in 1984\, a class of louds
 peakers was introduced by Bose\, designated &quot;acoustic wave speakers&quot;\, whi
 ch are more generically called transmission line (TL) speakers. Rather tha
 n suppressing the acoustic energy from the rear of the driver\, a means wa
 s engineered to use standing waves to constructively sum radiation from bo
 th the front and the rear of the driver. This allowed exceptional bass res
 ponse in a small volume. The TL speaker&#39;s science and operation in the Bos
 e radio context will be described. Analogies between antennas and the acou
 stic wave system will be used to help frame the analysis in electrical eng
 ineering terminology.\n\nCo-sponsored by: Antique Wireless Association\n\n
