BEYMAHaut parleur BEYMA 605 ND

• Exceptional power handling: 125 w AES

• High sensitivity: 100 dB

• 1.5. (38.5 mm.) edgewound aluminium ribbon voice coil

• Aluminium basket

• High efficiency: 3.3 %

• Excellent dispersion control due to the use of a phase plug

• Low harmonic distortion

• Linear frequency response


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.
