One of my friends had it in his apartment. They are large, powerful, and versatile, weighing in at about 30kgs. They come with Bluetooth connectivity, which can be used for streaming or internet radio. It also comes with a built-in phono stage, which allows one to hook up a turntable and listen to your favorite vinyl albums. The speakers use open baffle technology that provides better sound quality and acoustic transparency as opposed to traditional box enclosures typically found on many other speakers. I was told they are a limited supply and sell out quickly.
