RE: Why do subwoofers thump when turning on power amp?
Posted by John Elison on April 11, 2017 at 16:36:13:
Why turn it off? I leave my Rythmik Servo Subs turned on continuously. I leave my Parasound A21 power amplifier turned on continuously, too. My preamp has tubes so I turn it on and off, but it is totally silent---no thumps or pops at all.
Good luck,
John Elison
