The Good Solidly constructed; 250-watt amplifier; 12-inch woofer.
The Bad Somewhat big; bass can sound too boomy.
The Bottom Line This subwoofer has enough oomph to fill even fairly large rooms with deep bass.
Now that most folks are using small satellite speakers in their home theaters, subwoofers have become an absolute necessity. A good sub, such as JBL's gutsy PB12, can provide a major boost to the sound of movies and music. It delivers low bass with real gusto, though we found that it lacks pitch definition.Now that most folks are using small satellite speakers in their home theaters, subwoofers have become an absolute necessity.

A serious, big, black box
Even before you hear the PB12, you'll know that this isn't one of those poser subs; it's the real deal. This JBL is a fairly large, 40-pound cube, measuring 17.5 by 15.0 by 16.0 inches and finished in attractive, faux-wood, black vinyl. The PB12 has--you guessed it--a 12-inch woofer. More precisely, it's a pure-cellulose-fiber woofer, which is located on the bottom of the unit and fires down into the floor. An onboard 250-watt amplifier supplies the juice.
Hookup options cover every contingency. If you're using an A/V receiver, just flick the PB12's LFE switch, which bypasses the sub's internal crossover, and run an interconnect cable to the receiver's sub output. If you have an older receiver, you can connect speaker cables between the sub and the receiver. Either way, setup is a snap.
