Subwoofers - crazy upgrade!

The anti-DSP purist for subwoofers has never heard what taming a 12 dB or larger peak in a sub can do.   While there are many ways of taming a peak, not all are available to everyone or are equally effective.  

It's time we treat DSP for room modes like we do mental health and stop feeling ashamed.

How do you set up a Mini DSP for subs only? I have an external X-over.

Hey @tcutter  - Depends on how things are wired up.  The easiest way is to use a sub with line level inputs and put the miniDSP there.  It won't act as a high pass filter, but you still get all the parametric EQ goodness.  

If you want to keep DSP and filters out of your main audio chain, you can make things a little easier by plugging any ports on your main speakers.  This will naturally raise their cutoff point.   Otherwise, a single capacitor in line with your main amp is an effective 6 db/octave high pass filter. 

If I haven't suggested this before, the AM Acoustics room mode simulator and visualizer is fantastic.  I encourage everyone to use it even as just a learning exercise.
