    Question PSW250 Powered SubWoofer pops randomly

    I bought a complete Polk Audio home theater system several years ago. It included the PSW Powered Subwoofer. After I setup the system, the subwoofer immediately would pop randomly. I finally had to shut it off and haven't used it since. I should have seeked help when it first occurred, but I didn't. Anyway, what is causing these loud pops? What do I need to do to fix it? The subwoofer works, but the loud pops keeps it from being usable.

    Any advice is greatly appreciated. I am a complete noob with sound systems, so be gentle!

    It may simply be that you have the volume knob on the sub turned up too high. Try turning it down to half or even 1/3 of the range. Also check to see where your AVR has the sub set at. If it is -5 db, or a larger number, after lowering the volume on the sub, re-run your auto-cal program. Keep lowering the volume and re-cal until you get close to zero.

    Thanks RPF65.

    I really don't understand very much about audio devices, but I will study the documentation for the AVR and see if I can find what you speak of.

    I'll report back with my results.

    How often did it pop? Was it every few minutes? Did it happen when you went from having loud scenes moving to quiet scenes?

    Could be auto-shutoff causing the popping.
