Every component in the crossover is carefully selected for their audiophile quality and the crossover in the PHANTOM E-60 S is designed especially for this model.
The PHANTOM E-60 S includes PTC (Polymeric Positive Temperature Coefficient device) safety function. This safeguards the driver components from overheating if played at very loud volumes over a long period. Install speakers are often played to fill more than just the room they are mounted in, so If the listener is in another room the volume can accidentally be turned up to extremely high levels, and therefore permanently damage the speakers. The PTC system will prevent this for happening, since it acts like a fuse if the current get to high.
All internal wiring is optimized for the speaker design and is placed and secured to eliminate the possibility of rattling. The terminals are placed directly on the crossover for the shortest possible signal path, and the spring loaded grip ensures the best possible long lasting connection to the speaker wire.
