Hi Ken:
They essentially are the same as the Usher S-520s as they use the same drivers and cabinet. They use upgraded crossover parts, internal wiring, and binding posts. Which is said to take the speaker to another level. The color of these is different than what will be coming into the states.
It is a speaker, in my opinion, that needs a sub if used in a main system. If used in a computer rig that's different. Once you add a sub you have something special. I am selling my personal Sunfire True Sub MKII for $495.00 as I am not carrying the Sunfire line and need to focus on what I will be offering. The Sunfire works well with the Arte Formas.
The speaker is very lively and correct system matching is required. Don't pair them with silver cables, or bright equipment.
The retail on these was set at $599.00 which was way low in order to introduce them to the market. Very low margins involved. What I am selling this pair for offers ridiculous performance for the dollar. Contact me for pricing.
Here are some pictures of the demos I have. They were the ones that showed at RMAF. They don't have any grill cloths and have some slight shipping damage on the top right hand corner of one speaker. It's the first picture.




They do look really nice. I enjoy seeing them on stands in the room.
