Based on the phenomenal MASH noise shaping technology used for many years in Panasonic products, the Anti-Jitter Digital Amplifier markedly reduces jitter and distortion that can affect audio clarity, producing pure brilliant sound. The result is high quality sound with a full surround effect that rivals that of a real home theater SC-HTB550. The audio signal is wirelessly transmitted from the main unit to the subwoofer, eliminating troublesome wiring and restrictions on where the subwoofer can be placed for complete layout freedom. This speaker can be split into two by removing the connecting hardware in the center. Then you have four great installation options to suit your room. Try a horizontal or vertical speaker layout and have them free standing or wall mounted.
