Canton Vento 890 DC

I have read what few reviews there are in English. I was wondering if anyone has any real world experience with these speakers. I am planning on listening to them in the near future if I can find a retailer that has them on display. This will be used in a 2 channel setup. I will more than likely be using a sub with this setup. Any help would be great. Thanks!
I have the 809 DC's, part of an all Canton Vento system, and the sound is very smooth and musical with tight bass, I really like them though they have been in boxes for several months now due to a revolving door of speakers at my home.

They will benefit from a sub as they don't go as low as I'd like, and the Vento sub blends very well with them.
