Subwoofer Low Pass Filter Board with High Gain – PCB only

Subwoofer Low Pass Filter PCB Board (High Gain, Bare PCB)

This PCB is designed for building a subwoofer low-pass filter for audio systems. Performance depends on components used and assembly quality.

Working Voltage:

• Single supply: +12 V DC

Filter and Gain:

• Low-pass filter with adjustable cutoff frequency via potentiometer
• Bass boost: up to approximately 24 dB (depends on component values)
• Signal gain: approximately 10 dB (depends on configuration)

Op-Amp Compatibility:

• Supports dual op-amp ICs such as NE5532, TL072, JRC4558, LM833, OPA2134

Configuration:

• Designed for integration with audio power amplifiers (IC or transistor-based)
• Suitable for subwoofer signal processing applications

Construction:

• Bare PCB (components not included)
• Designed for through-hole components
• Components are commonly available

Board Specifications:

• Compact PCB layout for enclosure integration

Performance:

• Filter response and gain depend on component selection and assembly quality

Intended Use:

• Subwoofer signal filtering in home audio systems
• Car audio subwoofer systems
• Integration with amplifier circuits for low-frequency audio applications
• DIY audio filter and signal processing projects
