With so much attention paid to soundbars at the Expo, I was pining for the elemental simplicity of a kick-ass subwoofer demo. Fortunately, RBH obliged me with its new SX1212/R, shown here with RBH marketing director Daren Egan alongside for scale. Each of the sub’s dual 12-inch drivers packs dual 100-ounce strontium magnets, and the two are powered by a 3-kilowatt Class D amp. A 6-inch, bottom-firing port reinforces the drivers’ low-frequency output (as if they needed that). A scene from Battleship proved how satisfying a great subwoofer can be; RBH’s sound room shook as the monster sub kicked out explosion after explosion without audible distortion. The SX1212/R runs $5,000, which is a lot, but hey, the “R” stands for “reference.” Less-expensive models with somewhat less fancy drivers and separate amps are also available.
