The VO-CT compression tweeters are designed to thread into our VO-W woofers for coaxial applications or to be used with a standard PA style compression horn. These drivers cover the frequency range from where our VO mid-range and woofers leave off to the frequencies that send dogs running for cover. The motor uses CnC machined parts resulting in a close tolerance, high magnetic strength motor design. The diaphragm is a highly rigid, pressed titanium alloy connected to a high-temperature voice coil. The VO-CT compression tweeters come with an in-line 12dB/oct crossover. Plug and play high output has never been so good and so easy.
