The V221-S is a very high-output bass reflex subwoofer. The system is equipped with two advanced 21” RCF precision woofers mounted in a front-loaded configuration. This new high power design marks the latest refinements in RCF experience in compact subwoofer design, resulting in a fast and controlled reproduction of the bass frequency range. The two transducers couple to achieve tight and maximized output, while the subwoofer design ensures an efficient acoustic response down to 25 Hz.
