Woodbury, NY, firm Infinity Systems continues to put together affordable surround-sound systems that also achieve high marks in sound quality. Take the TSS series (which stands for total-solutions series). For just $549, you can have a full surround system. Yes, you read that right. You get four satellite speakers (3/4-inch tweeter with 2.5-inch woofer), a center channel speaker (1/2-inch tweeter and dual 2.5-inch woofers), and a 100W powered 8-inch subwoofer. If you’re not yet enjoying surround-sound, this system will get you started and not break your pocketbook.

But if you need more power, the series also includes the TSS-800 ($899) and the TSS-1200 ($1299). These babies add more power and incorporate Infinity’s MMD (Metal Matrix Diaphragm) driver technology for audiophile-grade sound.
