You can see my individual subwoofer measurements below to give you an idea of what my setup looked like. That means that you’ll need to take some preliminary steps before you start the EQ process. Instead of calibrating each subwoofer individually, most room correction systems will play all the subwoofers together and then apply the necessary EQ. ![]() One would think that all you need to do is setup the microphone, run the calibration and you’re done. Most room correction systems (ARC included) need some special attention when setting up a dual, triple, or quad subwoofer setup-regardless of how many subwoofer outputs are located on the pre-pro or receiver.

So a 7.1 system is seven speakers and one subwoofer and a 7.2 system is seven speakers plus two subwoofers, etc.īefore we start, I wanted to provide you with a graph (courtesy of SVS) of the anechoic measured response of the SB-13 Ultra subs. x always refers to the number of subwoofers. ![]() ![]() I’ll be using dual SVS SB13-Ultra subs, which are in for a forthcoming review, as the subwoofers in a 7.2 home theater setup that I’ll be referring to in this article.
