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.

Product Highlights:

  • 2-way 4'x6'" speakers (pair)
  • polypropylene woofer with rubber surround
  • 1" silk dome tweeter
  • power range: 2-40 watts RMS (80 watts peak power)
  • frequency response: 80-20,000 Hz
  • sensitivity: 92 dB

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.

Crutchfield Customer Review (What's this?)

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

Get everything you’ll need to enjoy your new MTX TDX46

Reduce ambient road noise and your vehicle's "rattles," for better sound inside your car.
You'll need speaker wire to connect your speakers to your amp.
Keep your speakers clean and dry. They compress to fit behind your speakers.
These speaker connectors are handy if you're running new speaker wire or if your speakers have oversized terminals.
The right tools will help keep your installation simple and clean.
If your stereo doesn't cut the deep bass from your full-range speakers, a set of bass blockers can help prevent distortion and give you cleaner bass too.
