About the JBL 621F

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 621F 6-1/2" 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.

Product Research

Features

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.

Mounting: Without an adapter, these speakers fit standard 6¾" applications. Given their required cutout, they will also fit many 6½" applications without an adapter, but new screw holes must be drilled. Please enter your vehicle information to confirm fit.

Customer Q&A

4 questions already asked

Q
Is the 45 watt rms there total power of all the speakers or just the one?
[ Micah  Aug 22, 2020 ]

A
Hi Micah, The 45 watts rms is one speaker power, as you can see in the back of the speaker. Hope that help.
[ Phuong  Aug 23, 2020 ]
A
I'm no pro, but I imagine each speaker can handle 45w rms. Each output channel of the power amp or radio would have a rated output. Crutchfield Techs should easily answer this question.
[ JESS  Aug 22, 2020 ]
A
That is the rating for one speaker only.
[ Brian  Aug 22, 2020 ]
Q
Are the JBL Concert speakers exactly the same as the JBL Stage 3 speakers? Seems the specs are exactly the same for both lines.
[ F.E.  Jul 31, 2020 ]

A
I'm not familiar with the Stage 3 speakers, but am satisfied with the JBL Concert speakers as upgrade to factory speakers in my Honda.
[ JUDE  Jul 31, 2020 ]
Q
Would those speakers perform well on stock radio? Would sound better then oem speaker?
[ Mcampos  May 04, 2020 ]

Although I can't speak for certain, not knowing what oem speakers you have, these speakers are high efficiency speakers (92 db sensitivity) that will almost definitely sound better than your oem speakers. They are rated at 3 ohms impedance and that should give you more volume than oem which are probably rated at 4 ohms. I put these in to boost the volume of the low wattage factory stereo in my 2020 Hyundai Kona. The magnets and voice coils are bigger than what my oems had. That and the high sensitivity and low impedance gave the stereo more oomph. You should get a boost in volume and clarity- just don't expect the difference to be earth shattering.- for that you need more wattage.
[ Brian  May 27, 2020 ]
A
we have a toyota highlander and it has a jbl stock radio these replaced the front speakers in the doors seems to work well the adviser is the one that said they would replace the stock ones
[ papa  May 26, 2020 ]
A
I guess that depends on the output of the stock radio. Crutchfield should be able to tell you if they are a match. I paired them with a kenwood dmx 7706S and they sound great.
