About this item
Written by Crutchfield's Alexander H.
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 521F 5-1/4" 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.
