| Ohm's Law | The basic law of electric circuits. It states that the current [I] in amperes in a circuit is equal to the voltage [E] in volts divided by the resistance [R] in ohms; thus, I = E/R. |
| Open Headphones | Open headphones have an open grille on the back of the driver, exposing the driver to the outside, and allowing the soundwaves to propagate away from the ear freely. This backing type does not isolate the listener from outside sounds; in addition, sound through open headphones... Read More |
| Out of Phase | When speakers are mounted in reverse polarity, i.e., one speaker is wired +/+ and -/- from the amp and the other is wired +/- and -/+. Bass response will be very thin due to cancellation. |
