TECTONIC BMR TEBM46C20N-4B
Speaker Driver Full Range Paper 20W 4 Ohm 86dB 150Hz - 20kHz Ø 7.6cm
Tectonic's BMR range consists of wideband loudspeakers designed to cover a very large part of the audible audio spectrum. Thus, the TEBM46C20N-4B has an extended frequency response from 150Hz to 20kHz and a wide directivity. In addition, Tectonic combines flexible wave technology and piston operation to ensure high audio performance despite a very small speaker format.
