Features and BenefitsInverted Acoustic StructureFlow 80 utilizes an inverted space saving acoustic structure to achieve maximum excursion in shallow mount applications, while still reproducing powerful andaccurate low frequencies.Neodymium Magnetic MotorNeodymium magnets deliver up to 20 times the magnetic field per unit volume compared to Ferrite magnet to maximize performance while minimizing bulk and weight.2" (50mm) Voice Coil Wound on TIL (Glass Fiber) FormerFlow 80 is engineered with a 2" voice coil with a high temperature resistant TIL (Glass Fiber) former for exceptional power dissipation and stability.BMW-specific Chassis with Plug-and-play Connector is IncludedFlow 80 is supplied with a BMW-specific chassis and plug-and-play connector, which allows a "direct replacement" and makes for quick and easy installation of the select BMW models underneath the front seats.Harman/Kardon’s Clean Aesthetic DesignFlow 80 keeps with Harman/Kardon’s clean aesthetic, the silhouette of the speaker is a simple circle. The fabric-wrapped grill, reminiscent of other Harman/Kardon speakers, protects the cone from fallen debris under the seat.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.
