Description:

The Ultimax Series Dual-Voice-Coil subwoofer is purpose-built to move air and create clean, articulate, fast bass with Dual 2-ohm, 2-layer copper voice coils.

The Ultimax Series 12" DVC subwoofer is purpose-built to move air and create clean, articulate, fast bass. It has dual 2-ohm voice coils allow for stereo 2-ohm and mono 1-ohm wiring configurations when connecting to high current car audio and professional audio amplifiers to extract maximum power. For home audio applications, simply wire the voice coils in series for a benign 4-ohm load for greater amplifier compatibility. 
To improve power handling, increase thermal management, and reduce power compression, Dayton Audio designed the Ultimax Series with large black anodised formers and vented pole pieces, under-spider ventilation, and two-layer copper voice coils.

Over 1½" of travel (3/4" Xmax) is kept completely linear using dual spiders that also limit distortion and rocking modes. "Tall-boy" rubber surrounds with integrated gaskets maintain driver surface area during extreme excursion moments. Thick, one-piece Nomex honeycomb covered cones are covered with woven, heavy-duty glass fibres creating ultra-still cones that resist deformation. 
A large copper sleeve and copper pole cap in the motor reduce energy storage from inductance, with the side benefit of lowering distortion for "faster" response. Large dual-stacked, high-energy magnets handle the heavy lifting and bring QTS down to a level where Ultimax subwoofers can be used in vented or sealed cabinets and enclosures.

Features:

  • Extra-thick, one-piece Nomex honeycomb covered speaker cone with woven heavy-duty glass-fibre for high strength with high SPL.
  • Large dual-stacked, high-energy magnets.
  • Double height Tall-boy rubber surround for an extra-long linear excursion without reducing cone surface area.
  • 600W RMS long-term power handling.
  • Copper shorting rings and cap reduce distortion due to inductance variations.
  • Dual 2 ohm, 2-layer copper voice coils.
  • Large, vented pole piece and under-spider venting.
  • Black anodised aluminium former and pole improves heat dissipation.
