The TrAx80 is among the latest in a long series of high performance Terra installed loudspeakers. It incorporates our most powerful satellite woofer, an 8-inch ACAD fluid cooled driver combined with a 1-inch co-axial, fluid cooled aluminum tweeter. This high frequency driver is mounted using a tiltable/aimable socket assembly to optimize performance even if the system must be installed in a less than ideal location. The TrAx80 is designed for those who want the best in sound indoors or out with deeper bass and higher output than the TrAx60. *IP67: Meets or exceeds MIL-STD-810G standards (speakers must be sealed under the flange for the waterproof rating).
