REW instructions to test subwoofer compression on burst tones

[o2so]

Hello,

could anyone kindly point me to some laymen-level instructions to use REW to check if my subwoofer is compressing burst tones at my typical listening volume? I do not mean long-term (swipe-like) compression, I already know it compresses a fair bit in the long term test. But will it compress also on burst tones?
Thanks!

What do you mean "compress"?

If you turn the volume up 10dB does the output increase by 10dB or not. See section "Dynamic Range (Instantaneous Compression Test)" in reviews such as:

There isn't an equivalent section in the subwoofer tests there though.

REW’s Signal Generator can provide the windowed tones for this. I would look around 20dB above typical listening levels.

Look for the differences between output and input over a small range of tones covering the bandwidth of your subwoofer.
