Blue Series B62C 6-3/4

German engineering meets car audio

Helix builds their low-profile Blue Series speakers to fit into more factory speaker locations while maintaining their high standards for sound quality. Helix earned its reputation by paying attention to the details, and these speakers really uphold the family name.

The drivers

You'll hear excellent high-frequency detail from the 1" silk dome tweeter, while the polypropylene woofer supplies solid, punchy bass. An external crossover is included to keep the right frequencies going to the correct drivers. If you want to enjoy the little details in your music without breaking the bank, you'll want to check out these Helix speakers. Grilles are included.

Note: Helix describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.

Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

The tweeters fit the rear doors location perfectly , all you need is a hot glue or silicone on the back of tweeter, woofers are perfect fit too. The sound is decent but I am comparing them to my front door Hertz Energy (No fair) .Dont forget Dynamat to get the best out of these speakers.

Product Research

Woofer
Tweeter
Crossover

Woofer

Woofer: The B 62C component system includes woofers with injection-molded polypropylene cones and durable rubber surrounds. 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.

Magnet cover: The woofers are shipped with a rubber magnet cover to protect the speaker. If the cover is removed the depth changes slightly:

  • Top Mount Depth: 2.337"
  • Bottom Mount Depth: 2.504"

Size Classification Note: Crutchfield has traditionally referred to this woofer size as a 6-3/4", while some manufacturers, including Helix (Audiotec Fischer), call it a 6-1/2". Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.

Tweeter

Tweeter: The system uses 1" silk dome tweeters with neodymium motor structure. The tweeters can be flush mounted, surface mounted, or surface mounted at an angle using the included brackets. Once mounted, the tweeters swivel so you can direct them toward the listening positions.

Tweeter Dimensions:

  Frame Width Frame Length Cutout Diameter Mounting Height Mounting Depth
Flush Mount 2.160" 2.160" 1.835" 0.50" 1.0"
Surface Mount 1.845" 1.845" N/A 1.185" 0.4" (Screw Depth)
Angled Surface Mount 1.850" 1.835" N/A 1.355" 0.4" (Screw Depth)

Crossover

Crossover: Each crossover has screw terminal inputs and separate, attached 38" output leads for the woofer and tweeter. No crossover frequency or slope information was provided by the manufacturer.

Crossover Dimensions:

  • Length: 1.905" (plus wiring)
  • Height: 1.070"
  • Width: 1.385"
