Which Harman Kardon FIT speaker should I choose?
The FIT 4F, FIT 5F and FIT 6F are 2-way coaxial speakers that fit directly into your car's existing speaker apertures. They differ in size — 4, 5.25 and 6.5 inches — and power handling at 30W, 35W and 45W RMS respectively, so your choice will largely depend on which size suits your vehicle.
For greater flexibility, the component options are worth considering. The FIT 6C is a 6.5 inch 2-way set with separate crossovers rated at 50W RMS, and the FIT 96M is a 6x9 inch 3-way speaker rated at 55W RMS. The FIT 19T are standalone 0.75 inch component tweeters ideal for adding hi-res treble to an existing setup, with a 91 dB sensitivity rating and threaded flush-mount adapters included.
