A:AnswerTop down- 14-1/8” wide (side to side) x 14-1/2” deep (front to back) x 3-7/8” high (top to bottom)
Top up- same width x 15-1/2” deep x 14” high
The top only opens to about 45 degrees. This is quite adequate for function.
A:AnswerI Believe you need to hook up a wire from one of your speakers to the other. The Bluetooth only feeds one speaker. The wire should feed the other speaker
A:AnswerThis works well using Bluetooth output, or analogue mini-plug wired connection--whichever your sound bar supports. I use Bluetooth connecting to the speaker I use for my TV.
A:AnswerNo need to turn off, as when not playing, the device just keeps a LED light on. Since that draws so very little current, that would make it safe to use an extension cord to un-plug if you want. Also, current draw when playing is minimal.
