About the Infinity Reference 6800cs

Todd Cabell
Infinity's Reference component speaker systems feature smooth good looks and even smoother sound!

Infinity's Reference component speaker systems feature smooth good looks and even smoother sound!

These systems use full edge-driven textile dome tweeters — a high-performance tweeter design found on upper-end home speakers, not the W-dome (or balanced dome) tweeter commonly found in car speakers. A larger tweeter voice coil translates into increased power handling and less distortion at high output levels. Highs are clean, accurate, and free from harshness from 3,500 Hz and up. Infinity's intelligent "I-Mount" system allows for flush-, angle-, or surface-mounts of the tweeters.

The 6800cs Reference component system features a 5"x7"/6"x8" Plus One+ woofer (even larger than the previous Plus One cone) for increased output. The injection-molded polypropylene driver is lightweight, durable, and highly accurate; its hi-roll rubber surround provides smooth woofer excursion and long-term performance. The 2-way crossover includes 3,500 Hz high-pass and low-pass filters.

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.

Mounting: The speakers can be mounted in a 5"x7" opening, or, using the supplied adapter rings, the speakers can be top-mounted in a 6"x8" opening. The Crutchfield database contains the 5"x7" measurements. When mounted in a 6"x8" opening using the adapter rings, the speakers have the following measurements:

  • Depth as top: 2.276"
  • Mounting height: 0.523"
  • Flange height: 0.281"

Tweeters

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

I-Mount Tweeter Mounting System: The tweeters can be surface-, angle-, 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.
  • Angle Mount: Surface mounting the tweeters at an angle involves screwing the angled surface-mount bracket to the mounting location, then attaching the surface-mount cup to the angled surface-mount bracket. Next, insert and lock the tweeter into the surface-mount 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.

Tweeter Mounting Dimensions:

  Surface Mount Angle Mount Flush Mount
Mounting Height 0.934" 1.643" 0.504"
Depth 0.538" (screw depth) 0.482" (screw depth) 1.229"
Frame Diameter 1.646" 1.631" 1.998"
Cutout Diameter   NA NA 1.759"

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.

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

Mounting: There are two mounting holes in the base of each crossover.

Crossover Dimensions: L=4.308", W=3.109", H=1.398"
