"Watching the Blu-ray edition of The Dark Knight, I was astonished by what the PC12-Plus brought to the table when, in chapter 30, the Joker, dressed as the scariest-looking nurse I’ve ever seen, blew up Gotham City Hospital. The PC12-Plus rendered that and every other explosion with impacts that were shockingly visceral, deep, and clean. Although this soundtrack reaches down to some very deep frequencies, I unplugged all three of the PC12-Plus’s ports, as this brought the most slam and impact."

Added on May 21, 2009, 4:14 pmAs noted above, I compared the PC12-Plus with my MartinLogan Descent i ($3495), which many consider to be among the top-performing subwoofers available. The Descent has three 10" aluminum-cone drivers positioned in a balanced configuration. Each driver is powered by its own 250W amplifier, for a combined total of 750W. In short, matching the 525W PC12-Plus against the 750W Descent i is the epitome of unfairness. And for a component such as the PC12-Plus, which swings far above its league, that’s the way we like it!
In that hospital-demolition scene from The Dark Knight, the Descent i dipped low and punched hard. A friend thought the MartinLogan had a bit more headroom than the SVS, but I had difficulty deciding which I preferred. It turned out that my preference depended on which film I was watching. Both subs went low enough that my room and I (and, on one occasion, my downstairs neighbor) cried uncle. This was a major coup for the PC12-Plus.
