Great speakers, one of my best buys (second hand for ca 500 usd), they have done a fine job at my cottage.
They replaced Royd: The sorcerer, that could not stand the sea air here (clogged the treble drivers).
This is the model with the famous ribbon tweeter and a fast small woofer that complements it very well.
I could get a sub, but I've found I like the purity of these speakers on their own.
