I bought this very product offline from a local Store at first I thought the price is very high as it is not 5.1 multimedia system its 4.1 stereo speakers with thumping bass woofer but as soon as I attach it into my Videocon D2H HD set top box it gives me heart thumping bass at that very moment I thought it’s worth every penny I sent because first of all the main thing is the brand that is Sony so no doubt about the quality which is provided because I used it on the highest volume with the highest volume on the woofer side too and believe me guys I don’t feel any distortion as far as the hi miss and low are concern even though these days are full of multimedia speaker with 5.1 channel provided but on the question of quality cheap 5.1 channel speakers couldn’t provide even after many years of releasing so hands up for me thank you.
