Dayton Audio's Ultimax Series DVC subwoofers are purpose-built to move air and create clean, articulate, fast bass. Optimised for small enclosures and with over 1-1/4" of throw, the UM8-22 8" subwoofer is perfect for providing deep bass without taking up much space.
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, this speaker features large black anodised formers and vented pole pieces, under-spider ventilation, and two-layer copper voice coils.
Over 1-1/4" of travel (.67" Xmax) is kept completely linear through the use of dual spiders that also limit distortion and rocking modes. "Tall-boy" rubber surrounds with integrated gaskets maintain driver surface area during extreme excursion moments. The thick, one-piece Nomex honeycomb cone is covered with woven, heavy-duty glass fibers creating an ultra-stiff surface that resists 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:
- 16 mm Xmax makes this one of the highest excursion 8" subwoofers on the market
- Thick, one-piece Nomex honeycomb covered cone with woven heavy-duty glass-fibre
- Tall-boy rubber surround for extra-long linear excursion without reducing cone surface area
- Dual linear stiffness spiders limit distortion and rocking modes
- 300 watts RMS power handling
- Black anodised aluminium former and black pole improves heat dissipation
- Dual 2 ohm, 2-layer copper voice coils
