Nado1466 Posted September 24, 2023 Share Posted September 24, 2023 Klipsch HD Theater SB 3 with a wireless subwoofer connected to a soundbar. The sub has a constant rumble that changes amplitude with the volume control knob. I can hear the music, TV sound through the sub but the rumble is twice as loud as the audio. It's now nearly 9 years old but hasn't been used extensively. Is this a fix that i can undertake? Electrolytic cap bad or could be another typical aging component that i can switch out? Or pitch the sub? Quote Link to comment Share on other sites More sharing options...
