ISOGROOVE TECHNOLOGY EXPLAINED

• IsoGroove uses (3) main technologies in combination. It was developed by a team that developed components for Cambridge SoundWorks, A/D/S and JBL.
• The first and most significant is the speakers are arrayed such that the basic mechanical vibrations cancel each other.
• The surface was analyzed for vibration patterns. Strategically placed bracing minimize the vibrations even further.
• Lastly, a DSP (digital signal processor) is utilized at low frequencies to ensure that low frequencies are always balanced to provide maximum vibration cancellation regardless of musical content.
