Price unknown (1 unit, released in 1976)
The most compact and low-cost speaker system in the Bose lineup at that time.
The feature is that the high band is attached diagonally to the outside.
The unit has a 20 cm cone type unit for low band and a 7.5 cm cone type unit for high band.
By changing the angle of the deflector in front of the obliquely mounted tweeter, sound energy in the middle and high range can be controlled according to room acoustic.
The crossover network employs a dual flexible crossover network with two transition frequencies.
Because the woofer and tweeter share a common playback band for more than one octave in the middle range where the fundamental part of the instrument is concentrated, a flat and smooth frequency characteristic is obtained for all bands.
