HELIX

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Our take on the HELIX Blue B5X

by John Pollard

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 B5X 5-1/4

The Blue Series B5X 5-1/4" speakers make the most out of the power they're given, so they'll sound great paired up to an aftermarket car stereo. But they can handle up to 35 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 1/2" Mylar dome tweeter, while the polypropylene woofer supplies solid, punchy bass. 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.

Highlights:

  • 5-1/4" 2-way speakers (pair)
  • injection-molded polypropylene woofer cone with urethane surround
  • 1/2" Mylar dome tweeter
  • power range: 5-35 watts RMS (100 watts peak power)
  • frequency response: 70-22,000 Hz
  • sensitivity: 90 dB
  • top-mount depth: 2"
  • grilles included
  • warranty: 2 years
  • Our 60-day money-back guarantee

    Features

    Woofer Materials: Each woofer cone is made of 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.

    Mylar Tweeters: Each speaker has a 1/2" Mylar dome tweeter for clean, accurate highs.

    Magnet cover: The B 5X are shipped with a rubber magnet cover to protect the speaker. If the cover is removed the depth changes slightly:

    • Top Mount Depth: 1.867"
    • Bottom Mount Depth: 2.099"

    HELIX Blue B5X

    Written By Danny, VAncouver, WA on Monday, May 06, 2013
    Installed in a 1983 Mercedes-Benz 300D-T
    Crutchfield Customer Review (What's this?)
     
    I installed these in my 1983 300D Mercedes. I would have givin these speakers 5 stars if I could have used my OEM grills.
    Pros:
    great sound
    Cons:
    These speakers are a little to big to fit in the OEM holes.Had to rip out speaker hole supports and could not use OEM speaker grills.

    Great Highs

    Written By Jimmy A., Puerto Rico on Monday, April 22, 2013
    Installed in a 2006 Porsche Boxster
    Crutchfield Customer Review (What's this?)
     
    I replaced my door speakers with the Helix B5X 5.5 inches. I found that they have excellent high tones. I am not impressed with low tones. Actually if I increase to much the bass the sound distorted. If you have larger drivers in your car these are a great addition, otherwise they do not provide enough bass by themselves.
    Pros:
    High and mid tones.
    Cons:
    Low tones.

    good replacement speakers

    Written By ldrmanbgft, Stuarts Draft, VA on Sunday, April 21, 2013
     
    Good repalscement speakers for my 98 Volvo V70 XC AWD. A whole lot better than the stock speakers. Decent bass, but, if you want thumping bass, then you better get a sub-woofer, as I plan to do in the near future. Overall, I am very satisfied with them.

    these speakers were a huge improvement over my 70$ a pair kenwood 6 1/4" speakers, yes even though those were a inch or so larger, these have a much better and more sensitive response. I don't believe I will put another brand of speaker in my car again.
    Pros:
    Great sound, easy install. Looks good.
    Cons:
    NONE

    Wicked speakers

    Written By Ryan, Massachussets on Sunday, September 09, 2012
    Installed in a 2005 Hyundai Accent
    Crutchfield Customer Review (What's this?)
     
    I ordered these speakers for my 05 accent coupe and I have to admit that these speakers are awesome. The 5 1/4 speakers are not "bassie" like a 6x9 is, however with a little tweaking and a few minuets you can tune in the sound with your head unit and get some decent results. If you have a car like mine with a relatively small interior volume, these speakers will make a big difference. If your looking for a bit more bass but not quite enough to shatter windows as you drive down your street take a look at the sound ordinance bt-8 for a better listening experience. If you have any further doubts about the helix b5x, just try them out I'm happy that I did
    Pros:
    Great sound
    Cons:
    No wiring harness, you'll have to hard wire these in to your factory system. It's easy as pie if you have a soldering iron
