HDS2.1 and HDS3.1 Release

The HDS2.1 and HDS3.1 incorporate innovative upgrades from previous versions of the HDS line of subwoofers.

The new HDS2.1 woofers feature a green double stitched surround, and a larger spider (199 mm from 181 mm). The HDS2.1 now showcases a conical motor with a bumped t-yoke. This avoids bottoming out of the voice coil due to the larger spider. It also boasts two ferrite magnets coming in at 156 mm by 25 mm (6.14″ x 2″). The new HDS2.1s feature a starting mounting depth of only 6″ for the HDS2.110 (saving a half inch) and up to 7.5″ for the HDS2.115.

HDS2.1 Features Include:

  • Green double-stitched EROM surround.
  • Stamped powder coated frame.
  • Vented back-plate for optimal cooling and less turbulence in the coil gap.
  • 2.5″ diameter four-layer copper coil.
  • Conical back plate to allow more voice coil travel.
  • Heavy-duty push connectors for ease of install. (Accepts up to 10awg speaker wire).
  • Black electroplated top and bottom plates.Non-pressed, fiber added cone for maximum rigidity.
  • Power Handling 600W RMS/1200W Peak.
  • Available in Dual 2 and Dual 4 ohm configuration.

The HDS3.1 includes some of the same HDS upgrades including a green double-stitched surround, replacing the previous white one. The motor houses two ferrite slugs at 190 mm by 25 mm (7.5 in x 2 in), and a bumped t-yoke for longer travel. The new HDS3.1 woofers feature a mounting depth of only 7.4″ for the HDS3.110 8.7″ for the HDS3.115. The new motor hosts a powder-coated stamped frame and comes with a 199 mm three-piece spider system. This new system is a bit softer to allow for lower tuning and better performance.
