Samsung's 1000 watt HT-TWZ412 surround speaker system features wireless rear speakers and auto sound calibration, which configures the speakers' individual outputs for the most accurate sound reproduction. It's also paired with an upscaling 5-disc DVD changer which converts standard resolution DVDs to to full 1080p high definition, uncompressed via HDMI cable. It also includes an iPod dock for easy home listening through the HT-TWZ412's 5 speakers and subwoofer. The dual-mounting centre and surround speakers can be placed on shelves or mounted on a wall with ease. The system also features USB Host Play compatibility for inferfacing with any USB media device with no additional software, as well as Anynet+ connectivity, which allows the user to control multiple connected HDMI devices with a single remote.
