Building Acoustics Speaker
A powerful sound source designed for in-situ building acoustics measurements per ISO 16283-1:2014. The source provides uniform sound radiation. When used with the power amplifier Nor280, the high sound power level ensures accurate descriptors in measurement conditions that include high background levels, high sound insulation properties and large room volumes.
Nor275 is designed for placement on the floor and uses the floor as a mirror for emitted sound. The loudspeaker is designed to operate at full power for more than one hour continuously.
The Nor275 is designed to be used with the Nor282 power amplifier (Nor280 power amplifier) only. Using other amplifiers may damage the speaker and will void the warranty.
