The Q14 loudspeaker, launched in 1967, was the first in a line of Sinclair speakers that eventually gained a fairly solid following, even if the products' quality was occasionally questionable. With the addition of the Q14 to the Sinclair range, consumers could now buy a complete mail order stereo system from Sinclair, apart from a record player or the tape deck. (The other components were the Z12 amplifier, PZ3 power supply unit and Stereo 25 pre-amp control unit, sold separately).
