Rockford Fosgate T16 6-Inch 2-Way Coaxial Speakers

The Rockford Fosgate T16 is a pair of 6-inch, 2-way coaxial full-range speakers built for replacing factory door or rear-deck speakers with a higher-power aftermarket option. Each speaker combines a woofer and centrally mounted tweeter in one assembly, helping simplify a full-range speaker upgrade. They are designed for vehicles using 4-ohm speaker locations.

With 70 watts RMS and 140 watts maximum power handling per speaker, the T16 is suited to systems using either a capable factory radio or an appropriately matched aftermarket amplifier. Its 65 Hz to 22 kHz frequency-response specification covers bass, midrange, and treble reproduction within a compact coaxial format. The 88 dB sensitivity rating supports practical output from modest-power systems while retaining capacity for amplified upgrades.

The woofer uses a carbon fiber and polypropylene injection-molded cone with a butyl rubber surround. A 1-inch aluminum-dome tweeter with polyurethane suspension handles high frequencies. This combination is intended to provide a rigid cone structure and durable surround in typical automotive environments.

Rockford Fosgate integrates the tweeter crossover inside the speaker basket through its ICC, or Integrated Concealed Crossover, design. The built-in high-pass tweeter network uses a 12 dB-per-octave Butterworth slope, so there is no separate external crossover box to place. The VAST surround design increases effective cone area without increasing the speaker basket size.

The T16 is a practical option for listeners upgrading factory speakers while keeping installation straightforward. Its FlexFit basket allows some mounting-position adjustment, and included grilles, mounting hardware, and adapter plates broaden installation options. Use the mounting-depth and cutout measurements to confirm clearance behind the mounting surface before purchase.

• Aluminum-Dome Tweeter: Provides dedicated high-frequency reproduction.
• VAST Surround: Increases effective cone area within the basket.
• Multi-OEM Adapter Plates: Supports select 5x7-inch and 6x9-inch openings.

Design & Installation

The T16 uses a carbon fiber and polypropylene injection-molded woofer cone, butyl rubber surround, aluminum-dome tweeter, and polyurethane tweeter suspension. Its FlexFit basket uses slotted mounting locations for adjustment where applicable, while the concealed crossover keeps the installation visually clean. Rockford Fosgate also lists the speaker as Klippel Verified and CTA-2031 compliant for power handling.

Verify a 5.04-inch mounting cutout and 1.93-inch mounting-depth clearance before installation. The package includes a pair of speakers, grilles or trim rings, mounting hardware, and adapter plates for 5x7-inch and 6x9-inch applications; adapter modification may be needed for certain vehicle openings. Observe speaker polarity at the terminals and match amplification to the 4-ohm, 70-watt RMS-per-speaker rating.
