Impedance values: generally 8 ohms are thenominal values. Most of the two frequency divider boxes have impedance valuesof 8 ohms, and multi unit and multi frequency loci speakers also have 6 ohmsand 4 ohms. The smaller the impedance is, the higher the demand current will beand the higher the power required. According to the author"s opinion, the bestchoice for household speakers is 8 ohm impedance and better power amplifier.灯光音响|丹徒演出音响租赁|丹阳市音响租借公司
