Echo studios and sub

[thcdru2k]

I have two Echo Studios and an Echo Sub in a spare bedroom. In the Alexa app, I set Bass to -2, Midrange to -1, Treble to 0, and turned Spatial Enhancement off. I then connected a laptop to the TV and ran REW measurements.

My takeaway is that psychoacoustic smoothing is useful for judging broad tonal balance, but it can also hide important raw behavior. The Echo setup can look surprisingly balanced after psychoacoustic smoothing, while the raw response still reveals the complexity of a DSP-managed multi-driver smart-speaker/sub system.


w/ smoothing: surprisingly balanced

raw: not so pretty

Use 50dB scale for the charts, it's easier to compare with the rest we post here.

MMM measurements with VAR smoothing will give you a better idea for in room measurements.

Don't even need Var smoothing at that point.

MMM does a good job smooting (spatially averaging) the response on its own.
