Harman Kardon has introduced the Fit and Flow aftermarket car-speaker ranges. Harman Kardon Fit comprises fourteen speaker designs, while Flow contains four models, with the compact Flow 80 and Feel 700 subwoofers accompanying the speaker families.

Fit includes coaxial speakers, component systems, separate midrange drivers and tweeters, plus shallow-mount designs for locations with restricted installation depth. Formats include 6.5-inch and 6 × 9-inch speakers. The range uses fiberglass diaphragms with Harman's Plus One cone geometry, which increases effective radiating area within a given speaker-basket diameter. Selected models feature edge-driven textile-dome tweeters with specified high-frequency extension to 40 kHz, while some provide Uni-Pivot tweeter aiming.

Flow speakers use ceramic-coated aluminum Deep Ceramic Composite diaphragms and Plus One cone geometry. The Flow 600CF is a 6.5-inch two-way component system with a 120 W RMS rating, specified high-frequency extension to 40 kHz and Hi-Res Audio certification. Adding the Flow 300S three-inch midrange driver converts a Flow 600CF or Flow 601CFS installation from two-way to three-way operation without replacing the existing speakers. The range also includes the Flow 75T standalone tweeter.

The Flow 80 is a slim eight-inch subwoofer driver designed as a direct-fit underseat upgrade for selected BMW models. It uses a neodymium magnet and an inverted motor arrangement. A dedicated mounting frame and factory-style plug-and-play connector are included.

The Feel 700 is a complete active subwoofer combining a seven-inch woofer, an integrated amplifier and an aluminum enclosure measuring 58 mm tall. Its Class D amplifier delivers 125 W RMS. Adjustable crossover frequency, output level and bass boost provide control over the subwoofer's operation. The Feel 700 also supports installations using two units.
