just super, the boxes are considerably larger than expected in weight alone feel themselves "valent", and the processing is really really good. And the sound of the the things on it's own is indescribable. for my room, about 30m2 more than enough. The Kenwood K-711-S with 2x30 watt is to get more than enough of these boxes really really good music. Amazingly a lot of bass (The still can go pretty deep!), But also ability to locate and stage are pronounced available. For the price, there are difficulties which zufinden better. Can I also like that you can start small, and later to the (still affordable) big brother (Ultima MK40) extend. If the small already "go" so good, must be the hammer, the greater yes.
