Boston Acoustics A-150 (c. 1987)
Not much is documented about the Boston Acoustics A-150. The clearest record is a new-product note in HI-Fi-Stereo-Buyers (December 1987, p.15), which introduced the A150 Series III as a three-way floor-standing speaker system. Per that listing, the changes over the earlier A150 Series II were a 10-inch woofer with a copolymer cone said to improve transient response, and a 3½-inch midrange driver that also used a copolymer cone. A broad baffle design was said to ensure accurate tonal balance in a variety of room environments and placements.
The A-150 was rated for amplifiers of 15 to 125 watts per channel, with frequency response given as 39 to 20,000 Hz ±3 dB. It sat in Boston Acoustics' A-series speaker line, alongside models such as the A-100, A-200, and A-250. Past the 1987 listing, the record goes quiet. No original price, dimensions, or production span are documented, and the full scope of the Series II-to-Series III revisions is not recorded.
