I have to change my speakers every 2-3 years because their sound almost blasts away. Are their any good speakers and of what comapany so that they last longer. I am not a very avid hi tech music buff but i like to have 2 good speakers with melodious sound so that every beat can be heard. Suggest me some good speakers with their company and also will I need something extra like tweeters or stuff like that so that i can improve my sound quality. 2 most imp requisites - long lasting, good quality and range-Rs.300-800.
