I have recently bought a Philips Home Theater HTS5530/94, Serial no.: Kx1a1234332428 from Paul Electronics, Shakti Nagar, New Delhi.
Only after 6 days of my purchase the system started to make some difficulties. First & the major one is that my subwoofer is not working as it was upto first three days. It seems to be not working below the volume of 20. And very low afterwards. The base/bass sound is also kind of gross not clear from the woofer.
Also i got the info from this forum about sudden change(decrease & increase) in sound itself.
Please help me with my subwoofer, Philips was never meant to serve like that.
