Very lightly used and in good condition. Have the bill and box for the HTA9, but not for the subwoofer. Testing warranty of 7 days on subwoofer from my side.
Never used it much, hardly 10-15 times powered on. Like new, good battery life as well. I might have the box lying around. Got this from the US via a friend. Not under warranty, but a 7-day testing warranty for my end.
