The MSP3A uses a 2-way bass reflex system with a 3.9-inch (10 cm) woofer and 0.9-inch (2.2 cm) tweeter, and a built-in 22W power amplifier optimized for speaker characteristics. In addition, this cabinet has a similar size to the previous model "MSP3", and it has been significantly lighter (10.7 - 7.5 lbs (4.4 - 3.6 kg); more portable, and can easily handle changes in the installation location. In terms of sound quality, it faithfully inherits the "MSP Series" reference sound while being compact, and can be used in small private studios and post production, as well as for electronic instrument monitors and surround systems.
