CFS engineered the COXB6 to be everything you need in a midrange car audio speaker; delivering incredible sound, loudness, and reliability. The COXB6 coaxial utilizes a high performance ferrite motor, which is an extremely lightweight and powerful magnet, allowing this speaker to be installed in a wide array of applications.

No detail, material or design element went unexamined in each of the COXB6 speakers; the loudness, sound clarity, and overall reliability of this midrange is unprecedented for a speaker of its size, featuring a commanding 2” voice coil that is complemented well by an advanced air flow cooling design.

The high frequency section is a close spaced aluminum diaphragm assembly. The diaphragm is a 1” diaphragm that provides excellent high frequency response and superior power handling and durability. The horn loading is provided via a thru pole piece configuration The overall high frequency design provides very high sensitivity.
