criteria, optimize the setting of HP frequency control, which 
establishes the low frequency limit of your L & R speakers. Note 
the setting.

23.  At this point in the process, it is instructive to measure the 

acoustic response of the combined L & R system a second time, 
but this time with the addition of the subwoofer. Compare the 
results of this measurement with your prior measurements 
made without the subwoofer. Document these new measure-
ments. You should now clearly observe more output below 40 
Hz as well as good linearity.

24.  Now is a good time to experiment with different filter slopes. 

Simply follow the same procedures as above, being careful to 
note all settings. This second experiment can then be com-
pared with the first, using music and measurements. Pick the 
approach that gives the most satisfying musical results. 

To EQ Or To Not EQ

Using equalization (EQ) in order to optimize the performance of a loud-

speaker is somewhat like a medicine that, while useful, has serious potential 

side effects. Carefully and minimally used, it can moderate some serious acous-

tical problems, with little or no down side. However, applied injudiciously, it will 

cause more problems than it will cure.
