Subwoofer Filter 4558 complete Regulated Power Supply

Subwoofer Filter 4558 circuit

Hello friends, this time I will share the 4558 filter subwoofer circuit which is similar to the previous filter subwoofer. Why is a subwoofer filter needed for a power amplifier circuit? For the important problem of whether or not it depends on the usefulness of the power amplifier itself, whether the power amplifier is devoted to subwoofer speakers or not. If so, then this subwoofer circuit is very important.

Usefulness is very good, but it also can clarify the low tone and eliminate the middle tone and high tone, so that bass issued by subwoofer speakers getting kicked. Back to the topic of this subwoofer circuit, this circuit I design and I modify it by adding a regulated power supply circuit by IC 7815 and 7915. Below the circuit schematic of subwoofer filter complete power supply:

• 20Hz - 250Hz Frequency output filter
• 12V - 30V DC input voltage
• 12V - 25V AC input voltage
• Using dual op-amp IC: 4558D, JRC4558, NE5532, etc.
• Single gain boost
• Regulated Power Supply using 7815/ 7915 also can be using 7812 7912
• 2 Channel (Stereo Input)
• 1 Channel Output (Subwoofer Output)
