Klipsch stunned the boxed surround sound world back in late January with the announcement of three relatively affordable 5.1 sound systems. The middle guy (yeah, the HD Theater 500) just started shipping out to the earliest of adopters, and we just so happened to get our set in today. For $599.99 (MSRP), you get four surrounds, a center channel and a powered (100 watt) 8-inch subwoofer. Each satellite is a sealed enclosure finished in a high-gloss piano black, with a 2.5-inch IMG woofer (center channel has two) and a MicroTractrix horn-loaded aluminum dome tweeter (0.75-inches) packed within. We can say with certainty that these drivers are delightfully small, but if you're looking specifics, here goes: the satellites are 6- x 3.6- x 3.85-inches, while the center channel measures in at 3.6- x 9- x 3.85-inches. As for the subbie? 13.9- x 12.5- x 12.5-inches. We're setting this rig up as we speak to give it a listen and report back, but till then, feel free to peruse the unboxing gallery below.
