All systems manufactured prior to 1993 were 8 ohms and had an industry standard sensitivity rating of 1 watt into 8 ohms. All systems made after this date were 4 ohms and have a rating of 2.83 volts, which is actually 2 watts into 4 ohms, making them appear to have greater sensitivity. The total DC resistance of the wire must now be less than 0.4 ohms instead of 0.8 ohms. A response with this tolerance will almost certainly not be measured for the same speaker in a typical home environment. Frequencies below 250Hz are particularly influenced by the speaker location, room dimensions and construction.
