Plug & play under-seat subwoofer for select BMW vehicles.

The Harman/Kardon Flow 80 subwoofer delivers true, accurate and powerful bass performance thanks to its space saving inverted acoustic structure and powerful neodymium magnet motor with a large 2-inch voice coil. Designed to integrate flawlessly and equipped with a BMW-Specific mounting chassis and plug-and-play connector for a direct fit into select BMW models underneath the front seat. Plus, it also can be used to enhance bass performance in luxury Audi, Porsche vehicles. Keeping with Harman/Kardon's clean design language, the silhouette of the speaker is a simple circle. The fabric-wrapped grill is reminiscent of other Harman/Kardon speakers and protects the cone from falling debris. The front magnet creates the illusion of pushing the cloth grill into the speaker. The magnet's metal grill uses the iconic Harman/Kardon 60-degree slash pattern, based on the "/" in Harman/Kardon, which provides venting for peak performance.
