Description
Ciare SPL CTB25-4 Shallow-Mount Bullet Tweeters
Sale unit: Sold as a pair — two tweeters.
The CTB25-4 is built for high-output systems that need a compact tweeter without giving up sensitivity. Ciare uses a 1-inch aluminum planar diaphragm, neodymium motor and shallow 2.28-inch outside diameter, making it easier to package into custom pods, fairings and panels than a large-format super tweeter.

Where this fits in the build
Speaker choice should follow the listening goal and the location it has to work in. Factory replacement, sound quality, loud daily and high-output builds have different priorities.
