Our Product Research Team

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.

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 4X are shipped with a rubber magnet cover to protect the speaker. If the cover is removed the depth changes slightly:

• Top Mount Depth: 1.622"
• Bottom Mount Depth: 1.815"

Removable Mounting Tabs: Most 4" factory speakers use four mounting screws, however, in some vehicles, only two are used. In these cases, you can bend the unnecessary mounting tabs until they break off. The B 4X also includes the mounting clips used in some older European cars (in this case, all four mounting tabs are removed). Care should be taken handling the speaker after any tabs are removed because the broken edges may be sharp.
