Panasonic has provided the SC-BT100 with special audio technologies that complement the superb quality of its Blu-ray Disc images. The Bamboo Diaphragm Speaker, which was developed by an extensive study of speaker cone materials, achieves high sound quality. The Kelton Subwoofer produces rich, robust bass tones to match the large-screen, high-resolution images. And by aligning the two woofers directly above and below the tweeter, the Vertical Symmetrical Configuration Speaker achieves sharp, clear sounds.
