The Ktema is an excellent speaker. I listened to at the recent AV show here in Hong Kong for quite a while and whilst it was not run in at all it still sparkled.
If you look closely you will see a piece of wood that extends down the back of the speaker. This piece has holes in it at various locations and it lies just an inch away from two woofers that fire backwards. I was wondering where the bass was coming from since the drivers at the front are pretty tiny.
