bassics
Refers to da simple facts and properties of subwoofers.
One of da bassics of setting up a household stereo system is to consider da auditory comfort of other nearby humans when determining how much power to have in your amplifier, especially if you have large loudspeakers and/or love "heavy-thumpy-thump" music like rock or country... remember how da natives in da jungle would communicate with large drums because low-frequency sounds carry very well over long distances. Dat's why you can hear a hot-rodder "'way down da road" if he's got da volume on his in-dash stereo pumped up too loud.
