Our verdict

A round coaxial pair with a mica cone and a rubber surround. Check the mounting depth against your door, because hardware is not named.

Overview

Not a component set, this is a pair of two-way coaxial car speakers with the tweeter mounted on the woofer axis. Black ABS composite grills cover the front, and the cabinet-free frame mounts on the surface or flush.

The mica-injected polypropylene cone and polymer tweeter are the selling points, with a hybrid surround on the woofer. The limits are a short listed warranty and no named mounting hardware or wiring.

Who it's for

A driver refreshing a standard round factory opening with a bit more output will find the coaxial layout simple. Someone chasing component imaging or deep bass should choose a component pair plus a subwoofer.

Pros and cons

Pros
  • Pair of coaxial speakers in one order
  • Mica cone and PEI tweeter
  • Surface or flush mounting
  • Grills included in the description
Cons
  • Mounting hardware not listed
  • Short warranty period
  • Not water resistant

Performance notes

Sensitivity says how loud the pair plays for the power it gets, so a head unit alone can drive it more easily than a low-sensitivity design. The cone material affects stiffness and breakup, while the tweeter handles the highs from the same axis. Mounting depth decides whether it clears the window track in the door.
