Hear what you've been missing with these Infinity Reference component speakers. You'll hear subtle nuances and little details in your music that you may never have noticed before, as these speakers fill your car with bold, radiant sound.

The Reference 5030cs system features low-impedance 5-1/4" woofers, designed to extract maximum power safely from any amplifier or car stereo. Infinity uses oversized rubber surrounds to increase woofer cone area up to 30 percent over other speakers of the same size category. As a result, you'll enjoy efficient, increased bass output.

Mount the soft dome tweeters with a clear shot to your ears, and listen as a whole new world opens up in the tight confines of your car. Infinity includes its unique Starfish™ mounting brackets, so you can install the tweeters in a variety of factory speaker openings.

External crossovers direct the high and low notes to the proper speakers for great clarity and high efficiency. You can adjust the tweeter level for best performance in your vehicle. Let Infinity Reference components help you rediscover the fun of listening to music in your car.

Important Note: These Infinity Reference speakers use a low impedance design to pull more power safely from your car stereo or amplifier. This design is compatible with virtually all factory and aftermarket stereos.

Product Research

Woofers

Crossovers

Woofers

Plus One+ Woofer Cones: Each speaker uses a cone significantly larger than other speakers of the same size. This is accomplished by using a new basket design and hi-roll surround. The Plus One+ design offers greater bass output and a significant increase in efficiency.

Woofer Materials: Each woofer is constructed from Injection-Molded Polypropylene. This process of cone molding assures a uniform cone thickness for superior linearity and clarity. It is also lighter weight and more rigid for decreased distortion and improved bass response.

Hi-roll Rubber Surrounds: The hi-roll rubber surrounds allow the woofers a greater range of movement, resulting in longer X-max and more bass output.

Applications: Infinity's mounting system allows the speaker to fit in a standard 4-hole 5.25" application.

Tweeters

Tweeter Material: Each 1" tweeter uses an edge-driven textile dome for smooth, accurate highs.

Tweeter Mounting: The I-Mount tweeter mounting system and Starfish mounting brackets give you several different ways to mount the tweeters:

  • I-Mount Tweeter Mounting System: The tweeters can be surface- or flush-mounted with Infinity's innovative I-Mount system:
    • Surface Mount: Surface mounting the tweeters involves screwing the surface-mount cup to the mounting location, then inserting and locking the tweeter into the cup.
    • Flush Mount: Flush mounting is made easy through the use of the threaded flush-mount adapter and plastic locking nut. Once a cutout is made, the flush-mount adapter (with the tweeter installed) is inserted into the hole. The large plastic locking nut is threaded onto the adapter (from behind the mounting surface) to hold the complete assembly securely in place. When flush mounted, the tweeters may be angled for optimum response and imaging.
  • Starfish Mounting Brackets: The Starfish mounting brackets allow the tweeters to be installed in factory locations behind the grilles:
    • Surface Mount (behind grille panel): Once the Starfish bracket is trimmed, it is screwed to the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
    • Flush Mount (behind grille panel): Once the Starfish bracket is trimmed, it is dropped into the cutout in the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
    • Bottom Mount (to grille panel): Once the Starfish bracket is trimmed, it is secured to the underside of the grille panel. The tweeter must be inserted into the bracket and locked into place before the bracket is mounted.
    • Flush Mount (in-dash location): Once the Starfish bracket is trimmed, it is dropped into the cutout in the dash. Then, the tweeter is inserted into the bracket and locked into place.

Crossovers

2-Way Crossovers: These speakers include computer-optimized, voice-matched crossovers. Each crossover features an 18dB/octave, 3.5kHz high-pass network for the tweeter and an 18dB/octave, 3.5kHz low-pass network for the woofer.

Selectable Tweeter Output Level: Each crossover allows you to select the tweeter output level according to system requirements and personal preference. The tweeter level may be set to "+3 dB" or "0 dB."

Crossover Connections: The crossover inputs and outputs are gold-plated screw terminals.

Crossover Dimensions: W = 3.475", H = 1.1875", D = 4.5625"
