I've read here and there that placing the 2 subs in the same corner would be optimum. ...but I can't do that. Due to the room I have and the way the doors are arranged, (12w x 33l x 8h) I'm going to have 1 16-46pc in the front left corner, near the front left main and, the other SVS in the right front corner, near the right main. TV and center channel in the middle. Both are sealed corners, meaning there are no openings nearby to affect the subs. My equipment rack is going to be about 20 feet from the left main and sub, and it will be about 30 feet from the right main and sub. How big a deal is phase relationship going to be if I use the same subs, both in near identical corners? Is the distance going to come into play? I've also thought about getting a pc+ instead of another pc but, I was a little worried that with 2 different subs with 2 very different capabilites, that the phase would have to be absolutely perfect or else there would be so much cancelling out each other that I'd be better off with 1 sub. Wouldn't phase be less of a problem with 2 identical subs? Is 1 16-46pc+ more powerful than 2 16-46pc's??? Any help is appreciated. I'm getting close to finishing my new home theater room. The addition of a 2nd SVS is one of the last things left to do.
