I've been researching how to properly place and setup subwoofers, and I came across the following article: Stereo Subwoofers: Why Every Man Needs Two
I'll quote the relevant parts of that article below, but I'm interested in finding out what TV shows and movies have directional bass. I thought I'd check the lists of bass in movies--lists that exist on AVSforum--and I just finished reading about how to read waterfall charts--but I now realize that it would be hard for people to measure the bass content of movies and TV shows from each speaker in their setup, instead of or in addition to measuring it from their main seating position, because if you wanted to measure a movie that has a 7.1 soundtrack, ideally you'd do it on a 7.1 setup, and you'd have to play the movie 8 times, measuring the bass sound one channel at a time, and then optionally measure it with all channels active. So, I'm not expecting to see any charts that have charted each channel individually.
Nevertheless, I am still interested in finding out whatever information I can about directional bass in TV shows and in movies. Here are some things that the article that I linked to says:
"The 5.1 system adds one subwoofer purely for very loud "booms" as a special effect for telling stories as a part of a motion picture. Each of the other five channels also has low bass, and movies today have a lot of multichannel bass information if your system can reproduce it. [...] While 5.1 SACDs may have 5.1 channels, all of those five main channels are full-range, and each deserves a big speaker — or use five + one = six subwoofers! That's how it's monitored in Hollywood. [...] Bass has been released in stereo ever since 1982 on CDs, DVD-As, SACDs, and even in 5.1 movies, and we can hear the difference. [...] Even if we can't hear the direction of the lowest 32 Hz fundamentals themselves, we very much can hear the difference in phase between the two channels, and in stereo recordings, out-of-phase bass information would be summed to zero in a single subwoofer. With stereo subwoofers, any out-of-phase bass information in a true stereo (acoustic) recording is reproduced properly at full level, adding immensely to the perceived width and depth of the room in which the recording was made.
If you sum the bass to mono and try to squeeze it through just one subwoofer, all the out-of-phase information cancels, and reduces the level."
If we're going to have discussion about the topic of directionality of bass in movies, perhaps we should have that discussion in a separate thread in order to keep this
thread on-topic, and we'll expand it to include discussion of TV shows and other forms of recorded video content as well.
Edited to add: The article that I linked to is a bit sexist; sorry about that.
