About the Rockford Fosgate T252-S
The advantage of aluminum
The advantage of aluminum
Rockford Fosgate designed the Power T252-S component speaker system for audiophiles with a penchant for crisp sound. Each 5-1/4" woofer features a responsive carbon fiber/polypropylene cone and rubber surround that'll stand up to hours of high-volume jams. The separate 1" aluminum dome tweeter provides extended highs with phenomenal detail, even when the bass gets heavy.
The included external crossover network with its high-quality capacitors sports selectable tweeter levels and on/off axis switching, allowing you to sculpt the high frequencies to your car's interior. These components handle up to 75 watts RMS, and you'll want to power them with an outboard amplifier for maximum performance.
Strong performance, easier installation
Proprietary VAST™ technology increases the woofer's cone area without increasing the size of the basket, giving you deeper lows and more power handling. And open slots on the heavy-duty aluminum frame make it easier to install these speakers if the factory holes are slightly off, especially in certain European imports. Rockford Fosgate helps you out with the tweeter installation by giving you a recessed mount that fits a standard 1-3/4" saw hole. You also get a 6" x 9" adapter bracket for larger openings.
Installation note: You may need a pair of our universal backstraps to install the tweeters in the factory locations.

Injection-Molded Woofers: The woofer cones are injection-molded carbon fiber filled polypropylene. This molding process assures a uniform cone thickness for superior linearity and clarity. It is also light weight and rigid for decreased distortion and improved bass response.
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.
Phase Plug: Each woofer's billet aluminum phase plug enhances voice coil cooling.
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.
Multi-OEM Adapter: For mounting flexibility, the included brackets allow installation in 6x9 applications. When using the brackets the mounting height is 0.607" and the depth is 1.791" (top mount).
Mounting: The 1" aluminum dome tweeters have multiple mounting configurations; choose flush mount 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°. Depending on the mount used, the installed dimensions are:
|Flush||Surface 15°||Surface 30°|
|Mounting Depth||0.92"||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.
Specifications: The crossover slope is 18 dB/octave high pass and 12 dB/octave low pass. The crossover point for both is 3.5 kHz.
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. (When using only two amplifier channels, leave the bi-amp switch off and use the tweeter inputs.)
Wiring: The crossover inputs and outputs are set screw clamps; they will accept bare wire up to 10-gauge. (No speaker wire is included with the system.)
- Width: 4-5/8"
