Description:

This superlative low/mid range transducer features a synthetic loaded paper cone optimised for minimum delayed resonances with a smooth mid range roll off which eliminates “out of band” effects. Neodymium technology ensures superb versatility in situations in which a conventional ceramic magnet transducer is unsuitable on grounds of portability or ease of installation. The PDN.12MH25 excels as a high efficiency transducer perfectly suited to direct radiating or horn loaded mid/high applications. This transducer perfectly compliments our 15” and 18” neodymium transducers in a three-way system.
