Features

Product Overview: The MTX Road Thunder RT12X2A is a sealed hatchback-style enclosure, loaded with two 12" Road Thunder RT 12-44 subwoofers. The two woofers are wired in a series-parallel configuration in order to present a 4-ohm load at the enclosure's single set of terminals.

Enclosure: The RT12X2A is an acoustic suspension (sealed) enclosure constructed of 3/4" MDF (medium density fiberboard). The end panels are recessed about 1/2". The enclosure is covered with charcoal-colored, aviation-grade carpeting.

Woofers: The two RT 12-44 subwoofers have the following features:

  • Basket: a bright red, precision stamped basket for greater structural integrity
  • Cone: polypropylene cone with poly dust cap for superior stiffness-to-weight ratio
  • Surround: foam, stitched to the cone for added durability and style
  • Magnets: 35 ounces each
  • ALDS: Asymmetrical Linear Drive System; flat progressive spider and extended pole piece for smooth, linear, piston-like drive
  • Voice Coils: 1.5" for higher power handling
  • Venting: Spider Plateau Venting cooling system cools at the voice coil
  • Integral Tinsel Leads: woven into the spider for better bass extension with greater durability
