Title 12 ULTIMAX DVC SUBWOOFER - DAYTON AUDIO
Notes DAYTON AUDIO Dayton Audio's 12” Ultimax Series 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 1-1/2 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.Extra-thick, one-piece Nomex honeycomb covered speaker cone with woven heavy-duty glass-fibre for maximising strength and rigidity with high SPLDouble height Tall-boy rubber surround for an extra-long linear excursion without reducing cone surface area600W RMS long-term power handlingCopper shorting rings and cap reduce distortion due to inductance variationsDual 2 ohm, 2-layer copper voice coilsLarge, vented pole piece and under-spider ventingBlack anodised aluminium former and pole improves heat dissipation Note: All parameters derived with voice coils wired in series.
