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.
