Title: lack of control, will turn off automatically
Review: This product works well and produce a sound of acceptable quality. However when no signal is sent from the receiver, it will turn off automatically (nothing you can do about it) and this is extremely annoying since it will produce a click and you will notice a big difference in the sound every time there is signal in the input and the subwoofer turns on again. It should have a switch to maintain the subwoofer on all the time, as is the case in most powered subwoofers. This is typically not a problem if you are listening to some musical genres at high volumes, but is very annoying when watching movies or even listening to music at low volumes. Two stars only because of the price.
