Our take on the MTX Thunder65 Thunder Series 6.5" 2-Way Coaxial Speakers

The MTX Thunder65 is a pair of 6.5-inch two-way coaxial car speakers rated at 60 W RMS and 120 W peak, with 4-ohm impedance and 92 dB sensitivity. They use polypropylene cones, a shallow 2.063-inch woofer mounting depth, and MTX's Spider Plateau Venting for voice-coil cooling. At $57.65 for the pair at eBay as of November 4, 2026, they sit at the low end of their recent range, well under typical retail for a name-brand coaxial pair.

Best forDrivers replacing factory 6.5-inch speakers on a stock head unitBudget builds that want decent output without an ampShallow door mounts where depth is tightOwners who want a simple drop-in coaxial pair
Pros
  • High 92 dB sensitivity means loud output from modest power
  • 60 W RMS handling leaves headroom for a small amp
  • Shallow 2.063-inch mounting depth fits many factory locations
  • Polypropylene cones resist moisture in door panels
  • Grilles included in the box
  • Pair price under $60 at eBay as of November 4, 2026
Cons
  • Two-way coaxials put the tweeter low, so staging is limited
  • 48 Hz low end is modest; bass will need a subwoofer
  • Weather-resistant, not waterproof
  • No crossover network beyond a basic inline capacitor
  • Only 27 ratings, so the 4.3 score is a small sample

Are the MTX Thunder65 speakers worth it?
