The JBL Stadium sound-bar system produces 100 decibels of audiophile-quality sound with glowing-red LEDs synchronized to the music beat. Each of the two IPx6-rated weather- and splash-proof JBL Stadium sound-bar speaker sections contains a pair of 4-inch-long excursion midwoofers and a high-output tweeter. Coupled with a built-in 120W x 2 Class D amplifier, the system produces audio that can be heard clearly over the roar of an engine yet provides accurate, subtle reproduction when in quiet surroundings. $999.95; prospecelectronics.com
