Voy a poner algunos consejos del foro de REW de AVSForum (en la propia página de REW hay un enlace):

TIP: ALWAYS MEASURE FULL RANGE, IE: 10HZ – 20000HZ AS YOU CAN MANIPULATE THE GRAPHS LATER TO ONLY SHOW THE PORTION YOU WANT. NEVER LIMIT MEASUREMENTS TO ONLY 10HZ – 200HZ FOR EXAMPLE, AS IT ONLY TAKES A FEW MORE SECONDS TO DO A FULL MEASUREMENT SWEEP AND THAT DATA CAN BECOME INVALUABLE LATER

TIP: DO NOT RELY ON ROOM CORRECTION SOFTWARE FOR THIS AND ALWAYS MEASURE WITHOUT ROOM CORRECTION ENGAGED!

The preferred axis for ALL subwoofer graphs is:

VERTICAL = 45dB-105dB
HORIZONTAL = 15Hz-200Hz.


The preferred axis for full range graphs is:

VERTICAL = 45dB-105dB
HORIZONTAL = 15Hz-25,000Hz.

These values are defaulted into REW, but can easily change and must be set back to these axis for posting graphs.

Waterfall aka Cumulative Spectral Decay – This is a much more important graph than a simple frequency response and one we’ll surely be talking about it more detail. It’s also much more important we get this one right when sharing it with others as just like the frequency response, almost any waterfall graph can be made to look good, but we want the real scoop and not pretty graphs to sell acoustical treatments.
