I’m presently building a dedicated home theater \/ listening room. If I put the false wall for the screen where I’d like to put it, there would only be an inch or two between the original wall and the back of the subs. So I’d like to turn the subs 90 degrees so they’re sitting sideways with the ports facing each other so I can have easier access to the controls (ports and controls are on the same end). Because these subs are down-firing I wouldn’t think the orientation is going to matter except for the three big ports on each one facing each other. These are big subs (18w x 26d x 25h 1st generation SVS PB12+) that emit a fair amount of sound out the ports so I’m wondering how this orientation will affect the sound. I’m not sure if it’ll be an issue at all, or will it make the sound muddy? Or will it do just the opposite and start cancelling waves, or will it add a hump to the frequency response?
