Criterion TCD 310 speakers . The smallest and slimmest floor-standing speaker in the TCD series. In spite of its small stature, the TCD 315 S constitutes another fully mature speaker with a very long transmission line, which is folded several times within the cabinet. The two 15 cm bass units with low natural resonance are matched accurately to the transmission line and their extremely hard, embossed carbon cones generate very low accurate bass, even at high pressure.
