Earthquake Sound - Subzero 10

Description

The latest iteration of Subzero-10 is a tour de force of how advanced design and technology can come together to create superior sound quality. All aspects of the design have been perfected to the smallest detail, resulting in truly revolutionary woofer performance. Subzero-10 is capable of an incredible 2.5″ excursion. With excursion of this magnitude, Subzero produces levels of bass unattainable by conventional woofers. The extreme excursion ability coupled with the unique suspension makes Subzero extremely transient proficient. Even a light touch on the cone, easily moves it several centimeters. This ease of movement combined with the ultra-powerful magnet system results in a spectacularly fast and precise response. Subzero is free of the mechanical and electrical constraints inherent to common woofers.
Product Features

    Flat or concave woofer cone dust cap for additional rigidity and stiffness that does not flex.
    Poly-Ether draw SWE (Super Wide Edge) suspension for high strength, flexibility, and ultra-long excursion without mechanical breakup.
    Dual Nomex / Romex super spider with composite center and symmetric stitched tinsel leads.
    TCT (Turbine Cooled Transducer) technology prevents heat-derived compression and keeps the woofer at maximum efficiency.
    Octo helix voice coil for perfect electromagnetic coupling, identical thermal signature, lower distortion, higher performance, and durability.
    Double-stacked cobalt-ceramic high Gauss magnet system.
    Diamond-cut chassis with XLT geometry for rigidity and extra length between the spider and magnetic gap.
    Patented PSP (Parallel Series Parallel) terminal system.With a simple flip of a fuse, the voice coil can be configured in series or parallel to match the amplifier in use.
