A:AnswerI believe you will need a converter for the speakers to work outside the USA. For the price of a converter you might as well just get new speakers in the country you're going to. There is no visible switch for the speakers to swap between 110 and 220.
A:AnswerThe Logitech Z313 speaker system connects via a single 3.5mm audio jack, typically plugged into your computer or primary audio source. But, it cannot be directly connected to two monitors simultaneously.
A:AnswerThese are desktop speakers, they aren’t meant to be used on a tv. Which is why it only uses a 3.5mm jack. It’s meant for a pc or monitor. I’d suggest getting a soundbar. It’s slightly pricier but you’ll get better sound out of HDMI, and you’ll have a hassle free setup.
A:AnswerNo unfortunately they don't have any mounting holes on the back of the speakers. You could install a small acrylic floating shelf, the speakers themselves don't weigh very much.
A:AnswerI Believe this are the standard 3 ft. I have an average desktop table my PC is on the bottom and the speakers reach with no problem one in the far left and one in the far right with the subwoofer next to it. and the sound is well balance to the center of the screen I use.
A:AnswerYes but they have their own volume knob. I suppose you could just leave the Logitech controls all the way up and untouched and just control the volume with your Mac.
