Sweet, airy, detailed and dynamic. 93db efficient. These are the most recent models introduced in 2017. Dual back firing woofers make the room placement easier. I purchased these speakers from their original owner who lived half an hour away from where I live downtown Chicago. I was extremely careful with the transportation (I did it myself with the help of one other person). These are heavy but not to the extent that 2 people cannot easily handle it. They are about 2 years old. I have the original packing material and boxes. They don't come with crates, so storing the packaging is easier. 75 pounds each unboxed, and 95 pounds each with the box and packaging. Pick up only.
