The T930 II was a slight revision of the original T930. The 930 was introduced around 1987-88. It was a 10" 3-way acoustic suspension speaker , with a 6 1/2" midrange and a 1" soft-dome tweeter.
BA's design/engineering was extremely competent at that time, and the 930 was a very good, straightforward design. It had a gutsy, ever-so-slightly forward sound quality, solid bass into the mid-40's, and a relatively benign impedance that ensured good compatibility with mass-market receivers.
The Series II was identical to the original, except that the Series II inverted the tweeter and midrange (mid on top, tweeter below in the II), to improve its lobing characteristics. The Series II was intro'd around 1990, and stayed in the line until the VR20-30-40 floorstanding speakers replace the T Series (T830, T930 II, T1030) in 1994.
