An introduction to Bose 901 speakers: A classic design, updated several times since its introduction in May of 1968, and still in production 45 years later. There are detail differences among the various versions, chiefly the cabinet and grille styling and the internal structure of the cabinet. Most have a wood or wood-looking cabinet; a few were built having a glossy 'piano black' finish. There was a (now discontinued) version of the Series VI that came with its own amplifiers--and a $3500 list price.

Series I----1968 to 1973, acoustic suspension (sealed cabinet), drivers use 4 fasteners each to hold them in place Series II---1973 to 1976, acoustic suspension, improved high frequency response.

Series VI--1988 to present, Acoustic Matrix, drivers use 3 fasteners. This is current production, as of April 2013 its $1,398.95 list price includes two speakers and an active equalizer, with shipping and sales tax additional, of course.

Bose has periodically put the speaker system on sale for about a hundred bucks off, and some eBay vendors are not charging tax and shipping, which helps a lot. Amar Bose practically built his company on the reputation of these speakers. Although he now seems to concentrate on selling tiny speakers, headphones, and expensive table radios which DON'T sound all that good, the 901 series is a different animal in that sound quality was a real, driving force in the design and development of the speaker system. Since the current production is the Series VI; and it has been since '88 (TWENTY FIVE YEARS!), I suspect that there is presently z-e-r-o engineering effort expended on the 901 series speakers, Bose finding much greater profit in the cheap and tiny stuff. There are several things that make the 901 series speakers so special. The unique Direct/Reflecting design of the speaker causes most (89%) of the sound produced to be directed to the rear of the cabinet, away from the seating position.
