You said you want high Sensitivity
..................here some drivers
This 6.5” mid frequency loudspeaker has been designed on the basis of the 6MI90 with the purpose of improving the efficiency. The new one includes a high-energy neodymium magnet that increases it and reduces the loudspeaker net weight. Thus, the 605Nd is 3 dB louder and 30% lighter than the ferrite version. By the other hand, this loudspeaker is mounted with an special cast aluminium basket that reduces mechanical vibrations and increases thermal dissipation. All these improvements combined with the 6MI90 excellences (low harmonic distortion and extended frequency response), result in a superb transducer for sound reinforcement applications.

This compression tweeter is designed for use in multi-element loudspeaker systems in sound reinforcement applications that require high output, narrow controlled dispersion and long throw. This model produces a very high output level with flat response and excellent transient attack. This unit features an aluminium voice coil diaphragm assembly, which is field replaceable without soldering.
