Product details:

The Morel MDT-12 is a chamberless neodymium design that offers big tweeter performance in an ultra-compact package. Measuring only 3/4" deep, it uses Morel's standard 1-1/8" dome and a powerful neodymium motor for big sound. The ferrofluid in the gap, self-shielded design, and smooth overall response make this tweeter applicable to conventional two-ways and home theater systems.
