Subwoofer measurements

Independent testing of subwoofers allows buyers to evaluate them on a level playing field. Typically they are conducted outdoors using the ground plane method.

Things to look for in the results:

1. Extended bass response
2. Suitable max SPL
3. Low compression
4. Low distortion above 40 Hz and acceptable distortion below that point, with less attention paid to low orders of distortion (2nd and 3rd) and more to higher order distortion products
