After more than 30 years of developing speaker systems for top OEMs in the automotive and aviation industries, the breakthrough has arrived. The world first and game changer, the RMD= Ring Mode Driver speaker is the ideal point source. Whether long, oval or round, extremely flat (max. 18 mm), no surrounds, no spiders. The design, industrialisation and processes are simpler than with other speakers. Significant weight and cost savings: no grilles, no adapters, environmentally friendly and recyclable. Unique worldwide, RMDs are integrated into surfaces, with the membrane surfaces directly covered with flexible materials, layers and screens. This makes the RMD completely invisible without compromising audiophile performance – a dream come true for every designer and architect. The acoustic off-axis behaviour and transients are exemplary across 8 octaves up to 35,000 Hz, with no disruptive resonances, partial vibrations, etc. typical of normal sound transducers.
