Series Wiring links your speakers together Positive terminal to Negative terminal and the resistances of all the speakers are added together. Series Wiring INCREASES impedance. The mulitplier is the number of speakers and the starting nominal impedance. In other words, two 8 ohm speakers wired in series have an 16 ohm load MOL. Three speakers have a 24 ohm load, etc. (Series = Sum) This allows the amplifier to be more efficient and to run cooler but series wiring does increase the resistance that the amplifier sees. The amp does not put out less power as is commonly believed. The power output remains the same, but it can appear to be less because each speaker is only receiving a portion of the overall power.
Cathy grew up in NY, moved to Florida in 1975 and graduated from the University of South Florida, with a degree in broadcasting. She and her husband Glenn started The Speaker Exchange in 1977. (Glenn later moved into Audio/Video sales and installations). In 1979, Cathy went to California for JBL speaker repair training and later received advanced training from Frank Spain, the then head of the Electro-Voice service department. She has continued to advance her audio education through many CES, NAMM, and CEDIA trade show classes.
