Pioneer has recently unveiled its HVT audio system concept at CEATEC 2010 in Japan. HVT stands for “Horizontal-Vertical Transforming” where Pioneer is working on offering the flattest possible set of speakers in order to build-up ultra-slim products like wall-mounted all in one Home Entertainment that will for example (see photo) offer a Flat TV, with Flat 5.1 Virtual Surround speakers and iPod Dock (behind the mirror on the left side of the TV in the picture), or ultra Flat powerful Audio speakers and finally High-end high-quality ultra slim PC speakers.
