Harman Kardon Flow 600CF passive 6.5 inch 2-way component speakers
The Flow 600CF is a passive component set with a low-profile outboard crossover network. The crossover includes a 0 dB / -3 dB tweeter level switch to tailor output to the listener. Adding the Flow 300S 3 inch midrange expands the system into a full 3-way setup. Woofer baskets feature twisting louvres, a signature design detail of the Flow range.
The aluminium Deep Ceramic Composite (DCC) cones use constrained layer damping to push cone break-up modes outside of the passband, keeping the driver in ideal pistonic motion throughout its range. Plus One technology works alongside the DCC cones to deliver a natural, detailed sound.

About the Harman Kardon Flow 600CF
From our tech experts at CEN
The Harman Kardon FLOW 600CF is a passive 6.5 inch (165mm) 2-way component car speaker set rated at 120W RMS (360W peak) per speaker into 4 ohms. Aluminium Deep Ceramic Composite cones, 91dB sensitivity and a 45Hz to 40kHz response are matched by a low-profile outboard crossover with a 0dB / -3dB tweeter level switch.
Who it suits
Drivers upgrading the front doors who want a proper component set that runs from a head unit or amplifier without DSP. Add the FLOW 300S 3 inch midrange later to expand it into a full 3-way system.
Our tech experts advise
At 120W RMS per speaker the set rewards a dedicated amplifier rather than head unit power. Mount the tweeters high and aimed across the cabin, then use the level switch to tame brightness. Flush-mount adapters, screws, speed clips and an EVA gasket are supplied. Installs are priced per vehicle; get in touch for a quote.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Can the FLOW 600CF be upgraded to a 3-way system?
A: Yes. The outboard crossover allows the 600CF to run as a full 3-way system with the addition of the Harman Kardon FLOW 300S 3 inch midrange.
Q: Can I adjust the tweeter level on the FLOW 600CF?
A: Yes. The crossover has a 0 dB / -3 dB switch to tailor tweeter output to the listening position.
Q: What is in the box with the FLOW 600CF?
A: Speakers, tweeters, crossovers, threaded flush-mount adapters with plastic locking nuts, screws, speed clips, EVA foam gasket and the owner's manual.
