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"
