While superb sound quality is the ultimate goal of any home audio system, the realities of budget and even aesthetics often force compromises in sound quality. Well, the time for compromise is over. Now you can have it all - great sound, great looks, small size, and an unbelievably low price. The Monoprice Premium 5.1-Channel Home Theater System surpasses all expectations for sound quality in a small package. The four satellite and the single center speakers each use a 3 polypropylene mid-range driver and a 3/4 aluminum dome tweeter. They can handle up 100 watts of power and have an impedance of 8 ohms. The satellite and center channel speakers handle frequencies from 110Hz to 20KHz 3dB, with the crossover between the mid-range and tweeter drivers set to 3.5KHz. The powered subwoofer features an 8 downward firing speaker driven by a 200 watt amplifier. It handles frequencies from 30Hz to 150Hz (-10dB) and uses a variable crossover from 40-150Hz. The satellites measure only about 6.9 x 4.3 x 4.3 (HWD) and weigh about 2.9 lbs. each, making them easy to mount almost anywhere. The center channel speaker measures about 4.3 x 10.2 x 4.3 (HWD) and weighs 3.0 lbs. Both the satellite and center speakers are equipped with a universal 1/4 threaded insert mounting options and have rear-firing ports, so they sound best when there is some breathing room behind them. The subwoofer is a 12.6 cube and weighs about 20 lbs. It features four large rubber feet, which keep the downward firing driver off the floor. It includes both line and speaker level stereo inputs, so it can be used with any amplifier.
