Bass is omnidirectional, so it's not a real problem. Ordinarily you would place it in one of the four corners of the room, however this will give you a 3-6db bump in the bass and you don't know if you need that without analyzing the room first. Some rooms are bass deficient because of their shape and/or the furniture that they contain. Others are just the opposite. I'm assuming that you don't have any testing equipment to test where you're going to mix down, so you'll need to use your ears, which unfortunately is a last resort kind of thing, but it will get you in the correct ballpark. You'll need to get some sort of a pink noise generator and play it through the speakers while you're setting up the woofer. As you play the signal, move the woofer along the side of your wall until it is approximately the same volume as the mids and highs. However, don't do this for the first 10 minutes of listening to the pink noise, as your ears and brain will try to try to make some sense out of the noise and fool you. You should adjust to the pink noise after the first 10 minutes or so, but don't play around with the volume. As you move the woofer closer to the corner you'll notice the woofer as getting louder, depending on how your room is set up this could be good, or bad. Pay attention ONLY to bass intensity against the intensity of the mids and highs. Don't confuse intensity with volume. Most square rooms should end up with the woofer around a foot away from the corner, BUT your room may vary, so trust your judgment Kurt. You're doing the mixing, you're ears are being used, so it has to sound good to your ears alone. If someone comes in your room and tells you it sounds bad (which they might) then just ignore them. Most people think that accurate sound doesn't sound good, which is why God invented tone controls for those people. If you don't have pink noise then in a pinch you can use white noise. An AM radio tuned to static can be used for this. Also remember that after you find where to place the woofer you will want to second guess where you placed it. Some songs are mixed with more bass than others. This doesn't mean that you placed the woofer in the wrong place, it simply means that the song has more bass energy than other songs. Also, if you normally have someone else in the same room where you do your mixing, then make sure that someone else is in the room when you adjust the speakers. Otherwise their presence will throw off the accuracy of the room. Make sure there's no talking while they're in the room and you're analyzing. Hope that helps.
