I have Logitech x140 speakers and I am looking for a subwoofer to compliment them. I have a 3.5mm jack port on my computer that says "c/sub" so I'm assuming that I have to buy a powered sub and plug it in to that port. My price range is anything under $100, little over is fine.
Audio playback from an Android device through my PC speakers was decent at best. Lag was low, however there was a noticeable periodic pop to the audio playback (which may be related to my cheap Logitech X140 speakers). Both the stock Android music player and VLC functioned correctly, and audio from the Windows systems runs alongside the Android music (which is good when listening for PC notifications).
