If you’re interested in buying your first home theater speaker system and you’re on a tight budget, I recommend you buy the Infinity TSS-450 speakers. A budget 5.1 surround-sound system with a 100-watt powered subwoofer. According to some reviews, despite its low price, sound reproduction is very accurate and the system is capable of delivering pleasing bass in smaller rooms. Furthermore, experts say dialogue sounds crisp and clear. The sub is bulky, but the satellites are small – it would be of good use in rooms that might otherwise be overwhelmed by five full-sized speakers plus a subwoofer. The estimated selling price for this particular speaker is $175; definitely one of the cheaperst 5.1 surround speakers their is on the market.
