HiWave HIBM85C20-4/DD 4" BMR Full-Range Square Speaker 4 Ohm
HiWave's HIBM85C20-4/DD Balanced-Mode Radiator (BMR) features extended frequency response and wide dispersion compared to that of a conventional drive unit. It combines the benefits of HiWave's bending-wave technology and pistonic modes of operation. It is ideally suited for compact audio applications that require a full-range, high performance acoustic solution. A rare-earth, neodymium-based motor is combined with special cone dampers to ensure a small size that outperforms conventional drivers, especially in off-axis performance.
