Everything comes in a single box. It's been a while since I purchased the unit, but the dimensions of the box are aprox 5' tall, about 3' wide by 3' deep. The box is extremely heavy - probably over 100 pounds. Again, these aren't exact figures.
Everything comes in a single box, however don't think the box is just a tinny box, it is a might box. You can ship it international, but it will cost you a lot of money because of the weight. If I might speculate the, it dimension look like a washing machine dimension .
It came in a single box. The box was approximately 4 1/2 feet tall and approximately 3 feet by 3 feet square. It's a hefty monstrosity. Total weight was close to 150lbs (I think the box was marked 146lbs, but it's been long enough I'm not sure). My box had some slight corner crunch, but the components come packed rather securely in hard styrofoam and nothing was damaged.
Everything comes in one single box. The box is 3'x3'x5' (a.k.a "Huge"). I don't remember the exact weight, but it was around 150 pounds (needed a dolly to get it down the stairs). Best setup I've ever had though, can't go wrong with this system.
I don't know the exact dimensions, but it was at least 100 pounds. It does come in one single box, but it would probably be expensive to ship internationally. I'm a US resident and have a Prime account, so shipping wasn't an issue. If I had to guess the dimensions - I'd say 4.5 feet high, and 2.5 feet x 2.5 feet. I don't know what that is in SAW, us USA folks are dumb and don't understand the Metric system, even though it's perfectly logical :)
