Our take on the Helix Competition C62C

by John Pollard

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-built quality

Helix's flagship Competition line embodies their mindset as a speaker company — use high-quality materials combined with precise German engineering to create speakers that deliver reference-level sound. These speakers will bring out nuances in your music that you haven't heard in your car before, while providing imaging and staging comparable to a set of premium home speaker towers. Helix built the Competition speakers for the mobile audiophile who wants the same level of sound quality in the car as he or she enjoys at home.

Precision drivers

The Competition C62C component speaker set owes its smooth, detailed highs to a 1" silk dome tweeter. Helix uses Agave sisalana, an incredibly stiff natural fiber, to create a 6-3/4" woofer cone that delivers powerful, accurate low-frequency response, adding warmth and impact to your music. These components work together to create a natural, lifelike musical soundscape that'll make you feel like you're listening to your favorite performers live.

High-quality crossover

Helix builds the massive 2-way crossover network with the highest quality parts available, so it can guide the correct frequencies to each driver without any troubling "hot spots" or dropouts. You can adjust the tweeter level on the crossover to your preference, and you'll even find a second set of woofer outputs so you can add another set of 6CB woofers for more kick-drum impact. This Competition speaker system will inspire your driving time with its impressive soundstage and musical performance.

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.

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.



Woofer: The C 62C component system includes woofers made of sisal fiber with durable rubber surrounds. The mechanical advantages of sisal, rigidity and inner damping, result in faster transients and precise detail.

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: 2.54"
  • Bottom Mount Depth: 2.71"

Terminals: Each woofer has screw terminal inputs that will accommodate bare wire or spade connectors up to 0.315" wide.

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: The system uses 1" silk dome tweeters with neodymium motor structures and damped coupling (enclosure) volume. The flush mount bracket is an integral part of the tweeter housing. Each tweeter has a seven inch input wire attached. Speaker wire is not included with the speakers.

Tweeter Dimensions:

  Frame Diameter Cutout Diameter Mounting Height Mounting Depth
Flush Mount 1.962" 1.733" 0.336" 1.012"


Crossover: The crossover inputs and outputs are screw terminals and will accommodate bare wire or spade connectors up to 0.315" wide. The tweeter output level is adjustable by attaching the positive tweeter lead to one of three screw terminals on the crossover, +2dB, 0dB, or -2dB. A jumper changes the woofers' expected impedance from 4-ohms to 2-ohms, used when an optional second pair of C 6B woofers is added (item number 975C6B, sold separately). No crossover frequency or slope information was provided by the manufacturer.

Crossover Dimensions:

  • Length: 4.560"
  • Height: 1.630"
  • Width: 5.035"

The Best Mids On The Market!!!

Written By Mario S, IL on Friday, December 20, 2013
Little review on a component set that will not only play your tunes, but also sing to you.!

I have been in car audio industry for a quiet a long time, and that's about 15 years +, so when it comes to sound quality, performance, detail, This component set will come in wooden cradle, packed very nice and tight so nothing will happen to it while being shipped to your doors. When you first open up the box, you could tell this is a solid piece of hardware, woofers look great, cone looks amazing, surround is nice and tight, and connections are solid. Tweeters are also very nice, very detailed, and they won't harm your ears while playing your music loud. Crossovers, well they are built like tanks, I don't use them because I'm running Active setup, so no need for crossovers. These mids are being pushed by Mosconi AS 100.4 amplifier; amp is being bridged so they are seeing about 300 W Rms @4 ohms. I bet you wondering how do they sound?? They sound amazing, so detailed, drums, kicks, mid bass is so clean, and loud, I hear thing I never heard before, they make so much air, that I feel them in the doors while driving. Setting 80hz -4K hz @12db slope Just to add my doors are sealed, and sound deadened. Tweeters are also being pushed by another Mosconi amp, and they are simply amazing, no harsh, no peek noise. So detailed and natural sounding tweets. Get them installed properly, and you be amazed!!!
Clean, detailed, easy install, and they simply sound amazing.
Price! but you get what you pay for!
