The all-in-one N-series includes a 5.1 surround speaker system with a subwoofer and front speakers built into the HDTV, and two rear speakers to round out the experience. It also includes Digital Media Port (DMP) technology so you can access content from a wide variety of digital media devices (with the optional accessory cradle), BRAVIA® Theatre Sync for easier control of other compatible Sony devices, and BRAVIA Engine 2™ for picture quality that's as perfect as the sound.
