Helix Blue B5X
5-1/4" 2-way car speakers
Our take on the Helix Blue B5X by Crutchfield's 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.
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.
Speakers arrived quickly and as described. The sound is so much better than original equip.

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"
