Our take on the HELIX Blue B62C

by John Pollard
HELIX

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

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.

Blue Series B62C 6-3/4

The Blue Series B62C 6-3/4" component speakers can handle up to 50 watts RMS of real-world power, so hook them up with an external amplifier if you really want to bring them to life. The added power gets you better bass and more accurate stereo separation, and your ears will thank you for the extra juice.

The drivers

You'll hear excellent high-frequency detail from the 1" Mylar 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.

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"

Crutchfield Customer Review (What's this?)
 
Swapped out the B52Cs for 62s. I'm pushing them with a stock head and clarion 4-channel amp. The bass response it a bit better with the 62s, but there's not a ton. These aren't distorted by bass as easily as the B52Cs. Mids are great from the woofers. The tweeters are rather loud, but the highs are smooth. The crossovers could really use a 3-6 db reduction switch. I'm going to wire in an LPad eventually
Pros:
Nice, smooth mids and highs. Better bass handling than the 5 1/4 inch version
Cons:
Still not a lot of bass, but that's not what I was after really. Too much volume on the tweeters.

Crutchfield Customer Review (What's this?)
 
I normally look at the reviews on a product before purchasing it. There were no reviews on these at the time of purchase but after talking to crutchfields sales support, i decided to give them a try. The installation was very simple and straight forward. The crossovers that came with the speakers are about 1" x 2" with two sets of flying leads for the speakers. You simply attach your speaker wire from the head unit to two screw terminals on the crossover and tuck it away. The sound is better then stock but not quite what I was looking for.
Pros:
Easy installation. Crossover is about 1"x2" easy to tuck away.
