Can Adjusting Phase Help with Calibrating Your Dual Subwoofers?

In this video, I experiment with the phase setting, along with adjusting the parametric equalizers, on my PB-3000s. I used Y cables to reconnect the Definitive Technology BP-8080STs to work along side with SVS PB-3000s and show how I use a combination of the REW acoustic software and the SVS app to perform EQ. With this, the home theater will now be using all 4 subwoofers. The more the merrier.
