Even if Thiel hadn't given their new subwoofer line the slick name of SmartSub, I'd still say most subwoofers are stupid. Make that stoopid. Granted, I've had some good ones in the last few years, and that's no accident, since no reviewer would willingly submit to stoopidity. But, in an electronics marketplace where everyone's looking for a deal, the quality of the average sub that moves from a chain store into the home of some unsuspecting sap is dreadful. The average sub is a one-note gas box that loads up bass pitches with layers of spurious overtones and distortion. You needn't be a golden-eared audiophile to find it oppressive.
