Rockford Fosgate T1693 6x9" 3-Way Coaxial Speakers

The Rockford Fosgate T1693 is a pair of 6x9-inch, 3-way coaxial full-range speakers designed for replacing factory vehicle speakers with a higher-power aftermarket option. They combine the woofer, tweeter, super tweeter, and crossover functions into each speaker assembly for a more straightforward installation than a separate-component system. This makes them suitable for vehicles with 6x9-inch speaker locations where a fuller frequency range is desired. Verify the vehicle's available mounting clearance and factory opening dimensions before purchase.

With a 4-ohm nominal impedance and 100 watts RMS power handling per speaker, the T1693 is intended to work with compatible aftermarket amplification as well as appropriate factory or aftermarket head-unit power. Its 3-way layout is built to divide bass, midrange, and high-frequency duties across dedicated driver elements. The result is a broad frequency response rated from 50 Hz to 22 kHz. A properly matched amplifier can provide cleaner output at higher listening levels than a head unit alone.

The woofer uses a carbon-fiber-reinforced polypropylene cone with a butyl rubber surround. This combination is intended to maintain cone stability while allowing the surround to support woofer movement. Rockford Fosgate's VAST technology increases the effective cone area without increasing the basket size. That added radiating area supports stronger low- and mid-frequency output from the existing 6x9-inch footprint.

A 1-inch aluminum dome tweeter and 1/2-inch aluminum dome super tweeter handle upper-frequency reproduction. The speakers use an integrated concealed crossover, placing the crossover within the speaker assembly rather than requiring a separate external crossover box. This helps keep the installation layout tidy in door, rear-deck, or other compatible factory locations. The 3-way coaxial format is especially useful when there is limited space for separate tweeter mounting.

The T1693 can serve as a focused upgrade in a factory-replacement system or as a rear-fill or full-range speaker pair in a larger amplified build. Its 90 dB sensitivity rating at 1 watt/1 meter and 91 dB rating at 2.83 volts/1 meter provide useful output with moderate power, while its RMS rating leaves room for an external amplifier. Grilles, trim rings, mounting hardware, and a pair of speakers are included. For best results, match the amplifier's clean output and crossover settings to the speakers' power capacity and vehicle installation constraints.

Key Features

• 3-Way Coaxial Design: Combines woofer, tweeter, and super tweeter functions in each speaker.
• 100-Watt RMS Handling: Supports use with a properly matched aftermarket amplifier.
• VAST Surround Technology: Increases effective cone area without enlarging the basket.
• Integrated Concealed Crossover: Keeps crossover components integrated into the speaker assembly.
• Carbon-Fiber-Reinforced Cone: Helps the polypropylene woofer maintain stability during operation.
• Aluminum Dome High-Frequency Drivers: Uses dedicated tweeter and super tweeter elements for upper frequencies.

Design & Installation

The T1693 uses a carbon-fiber-reinforced polypropylene woofer cone, butyl rubber surround, aluminum dome high-frequency drivers, and an integrated crossover design. Its 6x9-inch oval frame is built for conventional full-range speaker positions, and the package includes grilles or trim rings for a finished appearance where appropriate. The speaker has a 4-ohm nominal impedance and a 1.2-inch voice coil. It is supplied as a stereo pair.

Confirm the mounting cutout, mounting depth, window travel, panel clearance, and factory mounting pattern before installation. The required mounting cutout is 5.77 by 8.51 inches, and mounting depth is 3.39 inches. Route speaker wire before fastening the speakers, observe positive and negative terminal polarity, and use quality connectors; an external amplifier should be selected to provide clean power within the 100-watt RMS-per-speaker rating.
