Features

Overview: The MTX JackHammer JH5512X2D is a dual 12" subwoofer enclosure. The vented enclosure houses two 4Ω, 12" JackHammer 55 series woofers wired in parallel to present a 2Ω load at the enclosure's one set of speaker terminals.

Vented Enclosure: The enclosure is made of 3/4" MDF, joined together using interlocking dado and v-groove construction. It's covered in black carpet on five sides and the front panel features a flat black PVC cover. The corners have rounded edges for a hand-built, custom look. The rear panel of the enclosure is built with an 80° angle so it can fit tight against the back of the rear seat. The enclosure also has a side-firing slot port for maximum output, and nickel-plated compression terminals (spring posts) that can handle up to 10 gauge bare wire, pin connectors, and single or dual banana plugs.

Dual 12" Woofers: The JH5512X2D features two MTX JackHammer 55 series 12" woofers featuring:

  • Polypropylene Cone: The woofer features a graphite-colored, stitched polypropylene cone with the MTX Audio Jack Hammer logo. Polypropylene is lightweight yet durable and offers efficient, dependable bass response.
  • Rubber Surrounds: The Jack Hammer series woofer features a rubber surround that is stitched directly to the cone for durability. The woofer's rubber surround uses FEA optimized roll geometry to maximize excursion without sacrificing cone surface area.
  • Voice Coil: The woofer's voice coil is wound with 428-degree High Temperature wire to ensure reliability even at loud volumes.
  • Spider Plateau Venting Technology: The Jack Hammer series woofer uses proprietary Spider Plateau Venting technology which helps push out air out of the voice coil and bring cool air in, adding to the reliability of the subwoofer and keeping it cool even in the hottest vehicles.
  • Asymmetrical Linear Drive System: The woofer's Asymmetrical Linear Drive System combines a flat progressive spider with an extended pole piece to reproduce smooth, linear motion for incredibility crisp, clean sound.
  • Black Stamped Basket: The JH55 subwoofer has a black stamped basket design for structural strength, a stamped back panel with MTX's aggressive looking Gothic logo, and a large rubber boot protecting the woofer's magnet.
