The Good The Klipsch Synergy Sub-12 is a full-size subwoofer that offers a down-firing 12-inch woofer, a 300-watt amplifier, and connectivity options that cover all bases.

The Bad A real wood veneer would look nicer.

The Bottom Line The Klipsch Synergy Sub-12, the company's most affordable 12-inch subwoofer, sounds great on music and movies.

Klipsch Sub-12 subwoofer

When it comes to subwoofers, size still matters. While smaller 6- or 8-inch subs can produce credible bass, once you experience what a well-designed 12-inch model can deliver, you won't want to settle for less. Most big subs come with hefty price tags, but Klipsch's mighty Synergy Sub-12 retails for just $499.

There's no denying that the Klipsch Synergy Sub-12 is big; its black vinyl dimensions measure up at 18 inches high, 15 wide, and almost 20 deep, and it tips the scales at 40 pounds. As heavy as it is, the medium-density-fiberboard box felt rather hollow and resonant when we rapped our knuckles against the cabinet. The woofer is a 12-inch, down-firing unit that's matched with a digital amplifier that delivers 300 watts of continuous power and as much as 650 watts of dynamic power. The Sub-12's adjustable feet can be used to eliminate cabinet rocking motions when the sub is positioned on hardwood or tiled floors.
