The purest and most tangible audio experience



The special and simple design of the RB3 of the Sonic Message Series (SMS) is probably the most important reason for the pressure produced by this ribbon loaded enclosure. The recent development of SA UltraCode was inspirational to the creation of the SMS RB3. The RB3 is designed to cope with very high levels of (inaudible) sound between 15kHz and 22kHz, the frequency bands SA UltraCode and Sonic Notify based signals uses.
