According to me Creative SBS is a very good speaker. I bought it with my assembled PC and its purchase price was Rs. 995 around. I do not remember the exact price of it because I bought this speaker 5 years ago. The sound quality is perfect as it comes with a sound box and 2 speakers.
There is a ridge on the volume rocker button from where you can understand how much sound is increased and decreased. It comes with a 3.5mm jack which should be inserted at the backside of the cabinet. It delivers a great sound in home and the ambience feels like a theatre. The best part of this speaker is the durability, it has been more than 5 years and still my speaker is perfect. Value for money is perfect.
