Eminence APT50 V3 35W 8 Ohm Supertweeter (APT-50 Mk3)

Developed for totally Eminence loaded cabinets, or as upgrades to existing devices, Eminence HF drivers achieve extraordinary levels of audio performance with the same unrivaled durability you demand from Eminence bass and midrange transducers. From the field-proven series of APT tweeters, through the 1" throat neodymium and ceramic based 1" throat compression drivers, to the workhorse 2" throat PSD 3006, you'll find an HF device to meet your specific power handling, frequency range, weight constraints, price and performance needs.

The APT50 Mk2 high-power super tweeter possesses extraordinary sensitivity thanks to a phenolic diaphragm, which has unique properties of stiffness and damping. By fluid cooling the voice coil, increased power handling and controlled low frequency behavior are assured.
