And donвЂ™t forget that you must have parallel walls and floor/ceiling. So the seating placement determined by the mode chart isnвЂ™t necessarily the right spot to put that chair. The distance from the walls is going to determine reflections that will mix in with the direct signal either in or out of phase, causing dips or peaks in the response. Here we apply the knowledge acquired last month. This works for many home theaters but obviously not all. The charts also assume that the speaker is against the front wall. You can always add some membrane absorbers placed strategically once the room is scoped out (future article). Studio designers also use this technique although I feel the safest bet is to build your walls as stiff as possible so they donвЂ™t flex. Another factor is, that depending on how your walls are built, they may vibrate and absorb some of the frequencies. Or maybe you need the isolation from your neighbors or airplanes. Now, this doesnвЂ™t work too well if you have neighbors who are getting all the bass you just let out of your house without a license. Some studio designers even use this idea to let some of the bass escape so that they can control it. It all depends on how stiff and dense your walls are.

These wavelengths that escape are not going to bounce back into the listening area out of phase to haunt you (cancellations).

Of course you will be subject to the first peaks and dips of the wavelength, but some of these frequencies (starting with the lowest) are going to pass right through walls and windows and just keep on going. The less contained a room is, the more low frequencies will pass through the walls. The room mode charts are based on some assumptions that wonвЂ™t always apply to your room.ДЇirst and foremost, the assumption is made that your room is infinitely contained i.e. So letвЂ™s not beat a dead horse, but letвЂ™s talk about an aspect that rarely gets mentioned. And you probably already applied some of that mode info you gathered when you first set up your room. Even the guys who angled their side walls. I know if you care about this stuff enough to read this article, youвЂ™ve probably already read a bunch of other articles about room modes. What we are trying to achieve is contiguous linear bass and you can do that sliding speakers on the floor. Even with my high resolution gear, I canвЂ™t measure any difference in frequency, phase or coherence with or without spikes. For instance, did I remember to tell you it would be much easier if you removed those speaker spikes first? No? Shame on me! Those spikes will have an audible effect on the low end but you donвЂ™t need them for the initial placement.

ThatвЂ™s okay because you canвЂ™t give all of the necessary information in just one article. I know itвЂ™s a daunting task and some of you are probably still procrastinating. And when finished he realized that he had improved his room more than buying any new piece of gear could have. So, when we last left our hero he had moved his speakers all over the room until he found the spot where they sounded best. Modern Home Theater, May 2003 вЂ“ by Bob Hodas
