Loudspeaker Nor283
The new dodecahedron loudspeaker Nor283 is a small, lightweighted, yet powerful and rugged dodecahedron loudspeaker designed for the most demanding field and laboratory applications.
It supersedes all previous Norsonic loudspeaker designs and performs impressive sound power level at low frequencies compared given the small physical size.
The output level when powered by the battery-operated power amplifier Nor282 is an impressive 123 dB LW.
