The inductance (L) and cupuuituncu (C) will determine llic frequency (It) ihnl the Speaker will reproduce. Refer to the chart below to determine the components required, - Use the capacitors specied. Nonepoluri7ed capacitors rated at over :25 V Should be used for C1 and C2 in the d gram. Because of the voltage oulpul of lhc umpliilu, il in very important to use non-polarized capacitors rated at or over 35 V. This will prevent a safely hgimrtl.
