The $399 PS 10 is Infinity's midsize powered subwoofer. An oh-so-boring cube shape is par for the course for subs, and this model's only available finish is black "wood grain" vinyl. But we brightened up the PS 10's appearance by removing its grille to reveal the 10-inch front-firing woofer. The distinctive silver baffle lends the sub a fresh look. Considering the PS 10's prodigious 250 watts, the unit is fairly compact: 14.75 inches high, 12.5 inches wide, and 16 inches deep. It weighs a beefy 38 pounds.
The PS 10's back panel offers speaker and line-level inputs; we predict that most people will run a single interconnect cable between the sub and an A/V receiver. The direct (bypassed) input enables the receiver's internal crossover to match the PS 10 to your satellites; that approach will always result in the best sound.
