Does anyone know what the +/- is on the frequency response that Louis list on his speakers?

i.e. 40Hz - 20Khz, is the 40Hz +/- 3db? 6db?

I’ve actually did some crude in room measurements in the past and my data corresponded to about a -5 decibels on his bottom measurement.

Usually +/- 3dB means -1.5/+1.5 IMO.
But I could be wrong.

I've found that small changes in speaker placement and room acoustics can sometimes make a bigger difference than expected. It's always worth experimenting with positioning before making any major hardware changes.
