Rockford Fosgate T1650-S Power 6.5 Inch 2-Way Euro Fit Component Speaker System (Pair)

A T1 Power series 6.5 inch 2-way component speaker system featuring a FlexFit 2 basket optimised for US, European, and import vehicles, 1 inch treated fabric dome tweeter, asymmetrical external crossover network, VAST surround technique, and carbon fiber filled polypropylene cone. Sold as a pair. Includes grilles, mounting hardware, and flush and surface tweeter mounting options.

Product Overview

The Rockford Fosgate T1650-S is a 6.5 inch 2-way component speaker system from the Power T1 series. The FlexFit 2 slot-mounted frame pattern allows for variable mounting position adjustments, making it compatible with a wide variety of US, European, and import vehicle applications including Euro-fit installations. Power handling is 80W RMS and 160W max per pair, with 4 Ohm nominal impedance and 88dB sensitivity at 1W/1M.

The system includes a separate 1 inch treated fabric dome tweeter with DDC (Discreet Dual Clamp) mounting hardware for both flush and surface angled installation. The external crossover network provides an asymmetrical 18dB/octave high-pass and 12dB/octave low-pass filter with user-selectable tweeter level, bi-amp capability, and on/off axis switching. VAST (Vertical Attach Surround Technique) increases the effective radiating cone area by up to 25%. The cone is injection-moulded carbon fiber filled polypropylene with a Santoprene rubber surround and a fatigue and tear resistant poly cotton spider. The stamp-cast aluminium frame and high-temp aluminium voice coil complete the construction. Grilles and mounting hardware are included. Sold as a pair. Klippel Verified and CTA-2031 compliant. Backed by a 1 year warranty.

Features & Benefits

FlexFit 2 Basket for Euro Fit and Universal Compatibility: The slot-mounted FlexFit 2 frame pattern allows variable adjustments to the mounting position, providing compatibility across a wide range of US, European, and import vehicles including Euro-fit applications.

1 Inch Treated Fabric Dome Tweeter with DDC Mounting: The 1 inch treated fabric dome tweeter uses DDC (Discreet Dual Clamp) mounting for concentric clamping pressure around the perimeter of the mounting hole, providing secure and easy tweeter installation in both flush and surface angled positions.

Asymmetrical External Crossover Network: The external crossover provides an 18dB/octave high-pass filter and 12dB/octave low-pass filter, with user-selectable tweeter level adjustment, bi-amp switching, and on/off axis switching for installation flexibility.

VAST Vertical Attach Surround Technique: The VAST co-moulded surround increases the effective radiating cone area by up to 25% for improved bass and midrange output from the 6.5 inch driver.

Carbon Fiber Filled Polypropylene Cone with Santoprene Rubber Surround: The injection-moulded carbon fiber filled polypropylene cone delivers rigid, accurate cone motion. The Santoprene rubber surround provides a long-lasting, temperature-resistant suspension.

Stamp-Cast Aluminium Frame and High-Temp Aluminium Voice Coil: The rigid stamp-cast aluminium frame maintains precise driver geometry, while the high-temp aluminium voice coil handles sustained power without thermal failure.

Klippel Verified and CTA-2031 Compliant: Klippel certification ensures the drivers are engineered and measured to the highest performance standards. Power handling is rated to CTA-2031 industry standards.

Frequently Asked Questions

What is the FlexFit 2 basket and why does it matter for my installation?

The FlexFit 2 basket uses a slot-mounted frame pattern that allows the mounting position to be adjusted within the mounting hole. This is particularly useful for Euro-fit vehicle applications where the standard mounting holes may not align perfectly with a conventional speaker frame, giving greater installation flexibility across a wide range of vehicles.

Does the T1650-S support bi-amplification?

Yes. The external crossover network includes a user-selectable bi-amp switch, allowing the midrange and tweeter to be driven by separate amplifier channels for improved output and control. Tweeter level and on/off axis switching are also user selectable on the crossover.

Is tweeter mounting hardware included for both flush and surface installation?

Yes. Hardware for both flush and surface angled tweeter mounting is included in the box, along with DDC (Discreet Dual Clamp) mounting that provides concentric clamping pressure for a secure installation in either configuration.

What is the VAST surround technique?

VAST (Vertical Attach Surround Technique) co-moulds the surround to the cone vertically, increasing the effective radiating cone area by up to 25% compared to a standard surround attachment. This improves bass and midrange efficiency without increasing the overall speaker diameter.

Are grilles included with the T1650-S?

Yes. Grilles and all required mounting hardware are included in the box.
