CCX AND TC X MODELS... WHAT IS THE DIFFERENCE?

CCX models have woofers specifically designed for infinite-baffle applications. In plain english, this means that they are designed to operate without an enclosure behind them. The bass response of the speaker will suffer significantly if placed in a small enclosure.

TCX models are specifically engineered for enclosed operation. This makes them ideal for wakeboard tower systems or other small enclosure applications.

Do not attempt to remove the tweeter from the grille or the grille from the speaker! The tweeter is permanently fixed to the grille and its wiring is permanently attached to the speaker frame. Attempting to remove the grille or the tweeter will damage the speaker and this damage will not be covered under warranty.
