Dayton Audio's Ultimax Series DVC subwoofers are purpose-built to move air and create clean, articulate, fast bass. Experience the apex of subwoofer design.





The Ultimax Series of dual voice coil subwoofers, from Dayton Audio, are not for the faint of heart. Built using the latest in subwoofer technology, Ultimax subwoofers are the pinnacle of low frequency driver design. An Ultimax subwoofer test the strength of your foundation with fast, articulate, gut-wrenching bass.




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 anodized formers and vented pole pieces, under-spider ventilation, and two-layer copper voice coils.




Nearly 1-1/2" of travel (3/4" 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. Thick, one-piece Nomex honeycomb covered cones are covered with woven, heavy-duty glass fibers 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.



Cabinet recommendations:

• Sealed 0.63 cubic ft. (net internal), f3 of 45 Hz with a 0.707 Qtc alignment

• Vented 1.75 cubic ft. (net internal, not including driver or port volume) tuned to 25 Hz with a 10" wide by 1" high slot port that is 24" long, which yields an f3 of 23 Hz


Note: All parameters derived with voice coils wired in series.
