Hello, I'm relocating to Germany and I'm wondering whether there is a simple possibility to run the Acoustimass 10 III with 220V. In the old times, I remember, there was always one and the same transformer in those units and you could change one connection to have the two primary coils in parallel or in series. There was no other difference between the Europen and North Amarican version.

Question edited for correct model name (not Acoustimis) and full model descriptions as they make two types.

No kidding but "good luck". Bose doesn't like telling anyone anything about the workungs or specs of their products. You'll only hear them tell you "it's the end all, be all product". And you're blindly supposed to accept that.

The setup is possible, but with several compromises. First off, to use the active equalizer, you'll need to insert this into one of the 2 channel AV channels limiting your listening with the equalizer to stereo only. The acoustimass subwoofer acts a driver/power regulator for the little cube speakers. It probably will not be able to drive the 901s at the correct level when attached to the Acoustimass unit as front left/right speakers. You could try running a dedicated set of speaker leads to the 901s which may work and still allow surround sound, but you'll lose the equalization capability on the 901s.

Depends where you moved from!

It should state on the device itself what voltage range it can accept.

Try eBay. Lots of Bose cables. Search engines provide faster answers than tossing something like this out to us for a possible answer.

YOU'LL GET IT ON EBAY

I've made a diagram of my serial cable. You can easily make one with some speaker wire and a 15-pin d-type female serial connector. Solder the wires as shown in the diagram.

You can buy it on ebay but it's cheaper just to make one. If you can solder, all you need is a female 15-pin d-type connector and a bunch of speaker wire. Here is a diagram of the connections.

Here's a diagram of the 15-pin serial input cable that came with my Acoustimass 10 IV system. You just need a 15-pin female d-type connector, one RCA connector and a lot of speaker wire. Here's my diagram:
