Speakers are like karate. Subwoofers are like weightlifting. The quality of a speaker is determined by subtleties: well-chosen drivers, just-right crossover points and slopes, and a perfectly tuned, solidly constructed enclosure. The quality of a subwoofer is determined mostly by its muscle: the size of the enclosure, the displacement of its driver, and the power of its amplifier.

Speaker Standouts
An old-school category sees surprising innovation

One could argue that this spring will see as much innovation in the speaker category as in headphones. But when you think about it, that's not really so surprising. After all, speakers can be almost any size, almost any shape, almost any weight, while headphones will always have to be small and light enough to fit on your head.

The CEA-2010 subwoofer output measurement lets us separate the great subwoofers from the merely good ones, in a way that's more reliable and repeatable than traditional measurements or listening tests. However, it's still not widely used.
