Minidsp You can create different filters for your sub. Highpass for ultra low bass to protect the driver from over extension. Parametric equalization of individual sub frequencies. You can get a umik 1 microphone calibrated by cross spectrum labs and use it with REW which is a free to use program for analyzing your room in any frequency band. After you measure the room you can see which frequencies are over boosted or have a suck out and you can use the minidsp along with room treatments and sub location to even out your bass. It can also be used for time alignment of your subs to your mains if the subs are away from your mains such as to the side or rear .
