The BAS Speaker

The BAS Speaker is the Boston Audio Society's journal, published nominally 4 times per year and distributed to paying members. (To become a member, click HERE )

Since 1972, the Speaker has provided a steady diet of substantial articles about audio topics.

The Speaker's perspective generally reflects a working knowledge of the scientific and engineering background of sound recording and reproduction, and an ongoing interest in music, recordings and music performance. The BAS Speaker is the main publication of the society, and is only supplemented by this website.

Some earlier BASS issues, previously available only directly by mail, are now available online, below, HERE .

Show your appreciation for the immense amount of dedicated work that went into both the original writing, gathering, editing and printing, PLUS the more recent scanning and conversion to PDF format, by joining the Society, HERE !
