Call Sonos sales.

I got it shipped via DHL express in Europe.

It came in each in separate boxes, in my case 7 because I also ordered the era stands and something else.

The weight of each component should be on the product page to add, if iI remember correctly around 27 kg

Knowing the weight of each Sonos product is not the complete answer for shipping purposes. Actual cost to ship products like Sonos is a combination of weight (including packaging materials), length, width, height measurements of the box and in some cases the girth such as with a soundbar. The aforementioned is termed as “Dimensional Weight”.

For example if you ship a product that weights two (2) pounds in a box that measures 20 x 12 x 10 the cost of shipping will be based upon the box measurements. Shippers take into account how much room in a truck or container a package will occupy. Larger packages although more profitable also occupy more space restricting the number of packages that can be loaded.

The point being that actual shipping cost may not be available via sales as they are not the logistics department that’s actually responsible for all mentioned above. 

If ​@thebiggiebu works in logistics he can figure out an estimate based on the given information.

if he’s just a customer wanting to estimate his shipping costs Sonos should be able to help, as free shipping is possible for a lot of locations.

Unfortunately, I live in a country that sonos does not deliver to. I want to buy and deliver a set to my friend who lives in the sonos delivery country, and then send it to myself using a third-party delivery service
