Play audio from nearly any device with the pair of steel Kanto Living YU6 2-Way Powered Bookshelf Speakers. They feature an RCA, 1/8 mini, and two optical TOSLINK inputs, plus built-in Bluetooth for wireless connectivity. The RCA input can function as either a line-level or phono input via a rear-mounted switch, and a ground terminal is onboard to attach to your turntable. A 5V USB port is also built-in to keep your phone charged during playback. Each speaker has a 5.25 Kevlar woofer and a 1 silk dome tweeter to produce a total RMS output of up to 100W. An IR remote is included, along with speaker wire and an 1/8 AUX cable for instant connectivity.
