This model was originally designated with a factory Part Number: FC152F01TC as part of the Sovereign Range, it fits tidily above the Sovereign 12-250TC, so has now been renamed the Sovereign 15-300TC. Some stock may bear part numbers of the original factory part number.
The Sovereign 15-300TC features a triple concentric cone design for extended high frequency response up to 15 kHz. Offering well defined full-range characteristics and vocal presence, the Sovereign 15-300TC performs well in standalone, single driver cabinet configurations for smaller applications. It can also be used effectively as part of larger configured systems with supplementary support from additional sub bass.
