About the JBL 6421F
Strong sound at a strong price
Strong sound at a strong price
Bring on the big fun of being there live, but leave off the big price tag — that's the idea behind JBL's Concert Series car speakers. Their Concert 6421F 4"x6" coaxial speakers deliver a strong sound with a striking design, accented by JBL's "exclamation point" logo on the tweeter. And the speaker's patented Plus One™ structure extends the surface area of the polypropylene woofer cone to give you a better low-frequency experience.
A match for any system
These 3-ohm speakers are sensitive enough that you can power them with an aftermarket stereo, but you'll get even better results feeding them power from an outboard amp.
Grilles are not included; the factory grilles should be suitable for most applications.

Plus One+ Woofer Cones: Each speaker uses a cone larger than other speakers of the same size. This is accomplished by using a unique basket design and hi-roll surround. The Plus One+ design offers greater bass output and an increase in efficiency.
High-Output Design: The 3Ω voice coil design compensates for the high in-line resistance of small gauge factory wiring, extracting more power from factory (or aftermarket) receivers. This results in clearer, richer sound for the listener.
Size Classification Note: The CT6421 comes mounted on a standard 4x6 bracket (the most common 4x6 application). While the brackets appear to be easily removable, they are glued in place at four points around the perimeter (in addition to the four screws, which are obvious). With the brackets in place, the speakers fit many top mount standard 4x6 and metric 4x6 applications. If the adapters are removed, the speakers will fit additional top mount metric 4x6 applications, as well as some bottom mount metric 4x6 applications.
