Review on πŸ”Š Nobsound Auto Car Amplifier Audio Subwoofer Bass Control Knob: Enhance Your Sound with Sub Gain Equalizer and Frequency Regulator by Joshua Romero

Revainrating 4 out of 5

No low-pass filter

This product works great as an amplifier volume control, but the frequency control is NOT a bass control. This is a subsonic frequency converter that does the opposite of what most people want it to do. It blocks low-frequency sounds, but doesn't prevent mid-bass sounds from reaching the amplifier.

Pros
  • Ideal for balancing the system with changing styles of music; Simple input and output connections, no additional wiring required
Cons
  • Negative element present
