Product Details

Tectonic Elements TEBM65C20F-8 3-1/2" BMR Full-Range Speaker 8 Ohm

 

Tectonic Elements TEBM65C20F-8 Balanced-Mode Radiator (BMR) features extended frequency response and wide dispersion compared to that of a conventional drive unit. It combines the benefits of Tectonic Elements Elements 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 such as a soundbar. An advanced ferrite-based motor is combined with special cone dampers to ensure a small size that outperforms conventional drivers, especially in off-axis performance.
