Rockford Fosgate T-4652-S
Power Series 2-way 6-3/4" component speaker system
Item # 575T4652S | MFR # T-4652-S
Our take on the Rockford Fosgate T-4652-S by Crutchfield's Alexander Hrabe
Rockford Fosgate's Vertical Attachment Surround Technique gives the Power Series speakers greater power handling and frequency response.
If you like your music loud and clear, Rockford Fosgate designed their Power Series T-4652-S 6-3/4" component system for you. These speakers can handle up to 150 watts RMS, which means you can crank this system for hours without a worry. The woofer features a cone made from woven Liquid Crystal Polymer fibers, with a special-design butyl rubber surround that gives you more cone area without increasing the size of the basket. Translation? You'll hear deeper, richer lows than you would from most speakers of this size.
The 1" LCP fiber ring radiator tweeter features an aluminum phase plug to give high notes the perfect sparkle in your car. Rockford Fosgate uses superior components to create a crossover network that eliminates the "hot spots" and dropouts caused by inferior crossovers. You'll find a nice selection of customization options, including three selectable tweeter levels, selectable bi-amp switching, and on/off axis settings.
Rockford Fosgate has simplified installation on all fronts. FlexFit slot woofer mounting makes it easier to install these speakers in case the factory holes are slightly off. And Discreet Dual Clamp tweeter mounting hardware makes it easier to install your tweeters in flush-mount applications.
All told, this Power Series system will enhance your driving experience for years to come.
Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.
Simply the best....

Woven LCP: Much stronger than aluminum, with better damping qualities, the woven Liquid Crystal Polymer (LCP) fiber woofer cones are light weight and rigid to decrease distortion and improve bass response.
Butyl Rubber Surrounds: The butyl rubber surrounds dampen unwanted harmonic distortion while maintaining linear geometry under extreme weather conditions. This leads to less distortion, superior frequency response, and superior durability.
VAST Surround: The Vertical Attach Surround Technique (VAST) increases a speaker's effective radiating cone area without increasing the size of the basket.
FlexFit: The Flex Fit frame utilizes slots (where possible) instead of single screw sized holes; allowing slight adjustment of the speaker when mounted.
Klippel Verified: The Klippel distortion analyzer, a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, lets Rockford Fosgate optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.
Size Classification Note: Some manufacturers, including Rockford Fosgate, call this size speaker a 6-1/2". Because it requires a larger cutout than a standard 6-1/2" speaker, Crutchfield has traditionally referred to this size woofer as a 6-3/4". Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.
Ring Radiator Tweeters: The tweeters use a Ring Radiator design, similar to those in many audiophile home speakers. The Liquid Crystal Polymer (LCP) fiber diaphragm is supported at two pivot points, with the voice coil attached approximately midway between the two pivots. Since there is a small unsupported diaphragm area, there is less opportunity to develop performance-robbing resonance. The aluminum phase plug helps prevent phase cancellations.
Mounting: The tweeters have multiple mounting configurations; choose flush or surface mount. The Discreet Dual Clamp (DDC) flush mount system provides concentric clamping pressure around the perimeter of the opening. The surface mount housing can be positioned at two angles, approximately 15° or 30° angle. Depending on the mount used, the installed dimensions are:
|Flush||Surface 15°||Surface 30°|
|Mounting Depth||1.025"||Screw Depth||Screw Depth|
Tweeter Level: A switch on each crossover allows you to adjust the output level of the tweeters; -2 dB, 0 dB, or +2 dB.
Tweeter Axis: Another switch on each crossover adjusts the tweeter output for on axis or off axis placement.
Bi-amp: The crossovers have discrete inputs for the woofer and tweeter, along with a bi-amp on/off switch, so each component can be powered by an individual amplifier channel.
Wiring: The crossover inputs and outputs are set screw clamps; they will accept bare wire up to 12-gauge.
