Our take on the MTX TDX46

MTX

Value and performance

If you're looking to upgrade from your factory speakers, MTX designed their Thunder Dome series speakers for efficiency, so they'll give you plenty of performance even when powered by your factory stereo. And MTX made sure that all these speakers deliver extended bass response, from the modest 3-1/2" to the big bruiser of a 6"x9". Best of all, they're covered by MTX's unique 5-year warranty.

Range of music

The TDX46 4"x6" 2-way speakers deliver a surprisingly full sound, courtesy of a polypropylene woofer cone with a butyl rubber surround. The 1" tweeter uses a silk dome design to improve high-frequency dispersion through your vehicle, bringing out details you might otherwise miss. These speakers handle up to 40 watts RMS, so you crank the tunes up and still get clean sound. Grilles are not included — factory grilles are appropriate for most installations.

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 Cones: The MTX TDX series speakers feature durable and rigid polypropylene woofer cones. Polypropylene is also resistant to the moisture and temperature extremes found in automotive applications.

Tweeters: Each speaker features a 1" silk dome tweeter. Silk is lightweight and great for high frequency extension and efficiency.

Mounting: Without using the included mounting bracket, the TDX46 fits many top mount standard 4x6 applications. After adding the bracket, it will fit many bottom mount 4x6 and metric 4x6 applications. (Metric 4x6 typically found in European cars.)

Warranty: Although the speaker reviewed and measured (taken from our first shipment) included information indicating a 1 year warranty, MTX recently changed to a 5-Year Prorated Warranty with the following terms:

  • Years 1-2: Products found to be defective in materials or workmanship during the first two years will be, at Mitek's option, repaired or replaced by Mitek at no charge. The warranty period does not renew, but continues on from the original date of purchase.
  • Years 3-5: The purchase price of an item which becomes defective after the first two years and prior to the end of the warranty period will be prorated and credited toward the purchase of a new MTX product. The amount of proration is determined by dividing the original purchase price by the number of months in the warranty period (60), then multiplying the result by the number of months remaining in the warranty period.

Although I was not thrilled with my 6 1/2 MTX Thunder Dome speakers, these have performed well. I will be keeping them.
