I am preparing to buy a excellent presenter system specially sound quality. Primary objective Songs and some Films. Also Fish is main priority for me. I need excellent bass. Will 2.1 program do or should I opt for 4/5.1, price should be under 3.5K. Also, my space is quite little and I do not think 4/5.1 will be a good option. what say? Also, I got this SRS application which creates old philips 2.0 speakers sound too excellent. So I need not go for super-hi-fy quality speakers and something under 3.5K should do. What is the suggestion? Also, at what budget do the speakers begin from?
