Newport Test Labs first tested the in-room frequency response of the Triangle Borea BR03 and if you look at the result they measured in Graph 1 you won’t need me to tell you that it’s outrageously good. The first thing to note is that the response between 150Hz and 7kHz is spectacularly linear, but indeed the entire response is linear, with the graphed response extending from 70Hz to 20kHz ±3dB.
The second point to note is the spectral balance is perfectly
