Hello all, I'm helping a friend set up his new Yamaha HTIB. This is the subwoofer that came with it: http://image.www.rakuten.co.jp/kbest/img1039920477.jpeg You'll notice that there is a hole on the right side of the unit, with the front having the Yamaha logo, and the contol panel being on the opposite side of the unit from the logo. The bottom is open, as you can see, and there is a conical opening underneath. Now with the current setup we have in mind, this hole on the right hand side will be facing a wall and will be very close to it (within 6 inches). Should I turn the subwoofer sideways, so this hole is facing forward into the room, or doesn't it matter? Thanks for your attention.
