Mini tweeters are of great use as they can be placed in areas where space saving is essential. These devices are also placed in portable audio devices such as earphones and Bluetooth speakers as well as in car audio systems that have limited space. Regardless of their small size, engineers try their best to make sure that a mini tweeter gives the best possible output. The use of powerful neodymium magnets and diaphragms that are both light and stiff allow for greater achievement of advanced technology. In automobiles, these can be placed on the dashboard or door corners which will make listening to music in cars more pleasant as these locations will give greatest high frequency sound response.
