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.

Speakers arrived quickly and as described. The sound is so much better than original equip.

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"
