About the Harman Kardon Flow 601CSF
From our tech experts at CEN
The Harman Kardon FLOW 601CSF is the active version of the Flow 6.5 inch (165mm) 2-way component car speaker set, rated at 120W RMS (360W peak) into 4 ohms with 91dB sensitivity and a 45Hz to 40kHz response. It carries the Flow range's 60-degree slash grilles, twisting louvre baskets and magnetic covers that hide the fasteners.
Who it suits
Drivers building a tuned system where the woofer and tweeter are set up individually. Unlike the passive FLOW 600CF, the box contains no passive crossovers, so choose the 600CF if you want a simpler plug-in upgrade.
Our tech experts advise
Plan the amplifier and tuning before you buy, as an active set is only as good as its setup. Tweeters come with flush-mount adapters and locking nuts, plus screws, speed clips and an EVA gasket for the woofers. Installs are priced per vehicle; get in touch to talk through your system.

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: What is the difference between the FLOW 601CSF and the FLOW 600CF?
A: The FLOW 601CSF is the active version of the 6.5 inch 2-way component set, while the FLOW 600CF is the passive version supplied with outboard crossovers. Both are rated at 120W RMS, 360W peak.
Q: What is in the box with the FLOW 601CSF?
A: Speakers, tweeters, threaded flush-mount adapters with plastic locking nuts, screws, speed clips, EVA foam gasket and the owner's manual.
