Subwoofer design has undergone a revolution. No, the physics of woofers, amplifiers, and enclosures haven’t changed.

HDBaseT™ is a technology that delivers high-definition video, audio, Ethernet networking, control signals, and power over a single Category 5E or Category 6 computer networking cable. The technology is meant to be used with consumer electronics and home theater equipment, and has a few benefits that are not offered by other types of connections. The initial version of the specification was announced in June 2010, and uses High-Definition Multimedia Interface (HDMI) signals over a network cable.
