Pro Sound Web: Visceral, deep, percussive, tight, punchy – just some of many words used to describe bass response. A prominent low end forms the foundation for many styles of music and helps get the audience moving.
Subs are specialized loudspeaker cabinets, typically operating somewhere inside the range between 20 Hz and 150 Hz, and they usually cross over into the full-range mains around 100 Hz.

From my limited experiences working in sound, I’ve learned that low sounds evoke a wide range of emotions, whether or not we're consciously feeling them. For instance, if you hear a high-pitched screech, your instinct is to feel pain and discomfort, though you know that nothing is physically touching you (that you can see). With lower sounds, we, all of the sudden, may be feeling scared or soothed or what have you, without really knowing why we feel that way. Another reason why we as humans connect with the bass sounds is that we can actually feel them. When you're right next to a speaker stack at a concert, you can feel the bass radiating through you since the waves are so far apart that you can physically distinguish them. When incorporating bass into a design, especially bass of this size, you have to consider the physical response you'll get from the audience because they're going to feel it if you're putting 18-inch bas drivers in your system.
I have been interested in sound since the beginning of my high school career. It is something that has always fascinated me and I would always find myself messing with various speaker combinations in my school’s theatre group. I never really appreciated the true experience of a sub until I went to my first concert, and the music literally moved me. Soon after coming home from that concert, I purchased a 10-inch 50-watt subwoofer for my home theatre room. Although it is relatively small, it still packs a punch and completely changes the experience when watching/listening to something. My favorite thing to do is close the doors and crank the sub and feel all the emotions that are created. The entire house proceeds to shake and drives my mom up the wall—she experiences very different emotions from the sound. Without a sub, the experience that you get while listen to something will have far less of an impact and you won’t realize what you are missing.
