Excerpt: The DD-18 is just plain mental. The thing is huge, black, and ever-so-slightly scary: its monstrous 18in-diameter Kevlar-reinforced drive unit (that's nearly 46cm!) is big enough to frighten small children.
Pros: Simply extraordinary power and depth, sensational integration, thanks to its sophisticated equalisation system
Cons: It’s huge, the Wilson Benesch Torus and Eclipse TD 725SW are slightly more musical, but neither can rival it for movie muscle
