The RAIV is powered by one single 10mm dynamic driver and the housing is made of a combination of stainless steel and wood. This is also another model of the “JRM” series – JAIB, RAIV and MEIZ.
These three models are assembled in a combination of 3 pieces. RAIV has a bass tone slightly lighter than JAIB and it is more balanced. RAIV is recommended for songs emphasized on atmosphere and live recording than songs that are emphasized on speed and sharpness.
