JBL Basspro8 100W DVC Power Subwoofer, 8-Inch Size

JBL BassPro 8 Slot-Port Enclosure: JBL’s slot-port enclosure is engineered and “tuned” to the optimal frequency by the JBL engineering team. The enclosure material is MDF (medium-density fiberboard) to minimize resonances and unwanted ring. Lightweight but stiff polypropylene woofer cone provides clean reproduction and superior durability in an easy listening or high volume venue. Built-in Class D 100 watts RMS amplifier: The JBL subwoofer system’s built-in amplifier provides electronics matched and optimized for woofer characteristics and enclosure acoustics. Class D operation also means the amplifier runs cooler and draws less current from the vehicle’s electrical system. JBL RBC Wired Remote: The RBC Wired Remote (optional) is an easy installation and can be mounted for convenient volume adjustment from the driver’s seat, which sells separately on JBL website. Oversized Protection Bars: The oversized protection bars project a “serious car audio enthusiast” statement, but more importantly they do an excellent job of protecting the speaker from accidental damage. Harman Standard Reliability Testing: JBL speakers have to undergo a testing process that would destroy lesser speakers. JBL freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time.
