The construction of the M150 is based on the S150, the legendary studio monitor and multi-channel cinema speaker that has been around for over 40 years. For small studios and personal theaters gathered in bustling cities, the needs of customers are consistent: increasingly compact spaces, resulting in increasingly compact speakers, and uncompromising sound quality need. Due to the advancement of unit electro-acoustic technology, the M150 can be further miniaturized without affecting the sound pressure level and other key parameters.
