Gradient 1.2 came on the market in 1988. Although the speaker model was in production for only two years, it was manufactured in fairly large quantities during the economically good times of the late 1980s in Finland. The 1.2 model also had time to undergo several technical changes and gradually took shape as its successor, which was already under development.
Compared to previous 1.0 and 1.1 models, Gradient 1.2 was made an easier load to the amplifier. However, the most visible difference in the 1.2 was in the metal grill of the tweeter array, where the grill is bit deeper at the middle of the tweeters. The previous tweeter element used in Gradient 1.0 and 1.1 was no longer available, so it was replaced with so called second version of the tweeter designed by Knud Thorborg for the Danish Peerless. Since the new tweeter version had a deeper cone profile, four “pits” had to be made in the protecting metal grill to avoid standing waves between the cone and the grill.
A Gradient 1.2 pair is for sale, having just undergone a full factory service. The surrounds of the midrange drivers have been replaced, and the speakers have been fitted with a Seas aluminium-cone bass driver. This particular pair features midrange drivers manufactured by the French company Audax.
