I have bought this sound system in the year 2013 and I cannot find a single deterioration in its quality. The sound system has 4 speakers and a woofer that builds up such a great voice quality to watch movies at home.
I bought it for 5500Rs. And the price was completely worth for the product they provided. The sound system does not produce any echo sound if you place every speaker at the perfect place as instructed in the manual.
I have experienced awesome sound detailing with this sound system. It is anytime better than any product in this price range.
