Treat your ears to a real premium sound upgrade. The Infinity® brand is known for a heritage dedicated to great sound reproduction. Whether it’s the lowest notes of a bass guitar, the wide bandwidth of a piano or the cymbal crash in the highest frequency ranges, the Infinity Reference X Series of automotive speakers has it covered. The REF-6500cx is a 6-1/2-inch (165-millimeter), two-way, high-fidelity component speaker set with a 3/4-inch (19-millimeter) tweeter and high-quality external passive crossover network. The system includes innovative features such as Plus One® (U.S. patent number 7,548,631 B2) polypropylene woofer cones and vented voice coils, true 4-ohm technology, edge-driven fabric soft-dome tweeters and a fully adjustable tweeter level control. Also included are mounting adapter rings to fit 6-1/2-inch and 6-3/4-inch (171-millimeter) factory replacement applications in newer GM and Chrysler® vehicles. REF-6500cx components are best suited for external amplifier power and can handle an impressive 270 watts at peak (90 watts RMS). Rigorous quality-control testing and voicing procedures ensure that they meet the tonal quality and power handling that you expect from Infinity products. Listen to the Infinity Reference X Series speakers in person, then decide for yourself. Whether you choose these components or another speaker in the series, your car’s sound system will transform when you upgrade it to Infinity Reference X. You’re going to love these speakers.
Product Features:
  • 270W peak power handling (90W RMS)
    The Infinity REF-6500cx 6-1/2-inch (165-millimeter) component speaker set handles a full 270 watts peak power and a very respectable 90 watts RMS. This power rating ensures that you’re choosing speakers that will work well with a varied range of products, whether you’re installing them as an upgrade to a premium factory-installed sound system with existing component separates or connecting them to an aftermarket head unit or dedicated power amplifier. (If you’re planning your audio-system layout, the recommended power for REF-6500cx speakers is anywhere between 5 and 200 watts.)
  • Plus One woofer cones
    The Plus One woofer cone is a patented technology designed to deliver more diaphragm area than other speakers in the same size class. Because of their increased cone area, Plus One cones move more air, thus playing louder and overcoming the road noise inherent in a car. By radiating more air more effectively, the speaker performs as if it were a larger model usually associated with better low-frequency response. The end result is bigger and better sound.
  • Vented woofer voice coil
    Infinity REF-6500cx woofers feature vented voice coils through their magnet and frame assemblies. Keeping the voice coils cool leads to greater power handling and increased reliability, and helps eliminate the power compression that can cause distortion. It’s just another way that Infinity engineers ensure that you’ll enjoy these speakers for the long haul.
  • 3/4" (19mm) edge-driven fabric soft-dome tweeters
    The powerful, edge-driven fabric soft-dome design in the 3/4-inch (19-millimeter) Infinity REF-6500cx component tweeter features greater power handling and lower distortion than conventional tweeters of similar size. These enhanced performance characteristics allow a richer level of detail in high frequencies and, in particular, vocal clarity that is lifelike because of the tweeter’s improved radiating patterns and power handling in combination with the REF-6500cx’s included passive filter network.
  • I-Mount tweeter-mounting hardware
    The Infinity REF-6500cx 3/4-inch (19-millimeter) component tweeter includes the I-Mount™ (U.S. patent no. 5,859,917) tweeter-mounting system, which allows easy flush mounting or surface mounting to give you more installation options. In addition, the speaker has a special Starfish™ bracket system that allows you to mount the tweeter easily in a factory dash or door speaker location originally intended for a midrange driver of up to 3-1/2 inches (87 millimeters) – and to install it easily behind the factory grille.
  • Dedicated passive crossover network
    The Infinity REF-6500cx component speaker set features a dedicated outboard passive crossover network with sandstone resistors and polypropylene capacitors to separate the correct frequencies and level-match the relative signal levels directed toward the woofer and tweeter. It also features tweeter level controls. You can easily adjust the tweeter output from 0 to +3 decibels to compensate for low and off-axis mounting positions, road noise or even the limited high-frequency response common in many highly compressed digital media files. You can handle the adjustment with a small button on the center of the passive crossover housing.
  • High sensitivity (93dB@2.83V/1m)
    A speaker featuring high sensitivity allows a wide range of power and definitively high volume levels without overdriving the audio system. Featuring a sensitivity of 93 decibels at 2.83 volts / 1 meter, the REF-6500cx speakers achieve excellent volume and musicality with as little as 5 watts RMS. These numbers mean simply great performance overall with even very moderate power driving the speakers. It makes the REF-6500cx speakers an ideal replacement for factory-installed speakers where there are already component locations (as in many premium audio systems) as well as for any aftermarket installation.
  • True 4-ohm technology
    Infinity Reference X high-fidelity speakers feature 3-ohm voice coils to ensure ideal performance, whether you use the speakers as an upgrade to a factory-installed audio system or connect them to aftermarket head units or amplifiers. By ensuring the safe 3-ohm load along with associated wiring and connections, the power delivered to the speakers is right on target with peak system performance and reliability, which is how the speakers’ true 4-ohm technology works. Get all the power you’ve paid for and enjoy effortless, high-quality sound in your car.
  • Easily replaces factory component speakers and vastly upgrades the sound
    The Infinity REF-6500cx component speakers are part of a complete range of automotive speakers that fit factory-installed locations in virtually every vehicle on the road today, including premium audio systems that already have factory-installed component speakers. These speakers still provide a significant improvement in those cases. All Reference X speakers leverage the extensive Infinity pedigree of audio and engineering innovations, and deliver remarkable sound in your car. You’re going to love these speakers.
  • Includes expanded-fit mounting adapter ring
    Infinity® REF-6500cx speakers include an additional set of mounting adapter rings to allow the woofers to fit securely in a broad range of factory speaker openings that match their size, particularly in many newer Chrysler® and GM vehicles.
