Rockford Fosgate Power Series T1650 6.5" Coaxial Speakers

Product Overview

Upgrade your car’s sound with the Rockford Fosgate Power Series T1650 6.5" coaxial speakers. Their integrated 1" tweeter and built-in crossover bring high and low frequencies together in one speaker, without a separate component tweeter.

The T1650 is designed for a wide range of US, European, and import vehicles. Use the matched pair to replace OEM speakers in front or rear channels and add clearer highs, fuller midbass, and coherent imaging to your system.

Key Features & Benefits

• Integrated tweeter and crossover: The bridge-mounted 1" treated aluminum dome tweeter sits close to the woofer’s voice coil axis, while concealed 12dB/octave crossover components filter high frequencies.
• Carbon fiber-filled polypropylene cone: Its combination of stiffness and light weight supports precise transients and solid midbass performance.
• VAST surround: The Vertical Attach Surround increases effective radiating cone area by up to 25%, boosting bass output without increasing enclosure size.
• Stable speaker structure: A stamp-cast aluminum frame minimizes flex and vibration, while the Santoprene rubber surround helps control cone motion.
• High-excursion design: Matched motor magnetics and suspension allow greater cone travel for deeper bass and dynamic range.
• Installation-ready pair: FlexFit 2 mounting, grilles, a grille/trim ring, and mounting hardware support a finished installation.

Its cone, surround, and high-excursion suspension are designed to support responsive midbass and greater cone travel, while the aluminum frame provides a rigid mounting structure.

At 4 Ohms, with 75W RMS and 150W Max power handling, these speakers suit a system planned around their stated ratings. Their 88 dB sensitivity benefits from a capable head unit or modest amplification.
