Dayton Audio 12" Ultimax Subwoofer and Cabinet Bundle


About the Cabinet

This particular cabinet is designed specifically for the Dayton Audio 12" Ultimax subwoofer, but works for any subwoofer with an overall diameter of 12-3/8" or less, and a cutout requirement of 11-1/8" or less. For optimum performance with the Ultimax 12" subwoofer, add one pound of Acousta-Stuf polyfill for a Qtc of 0.707 and an f3 of 36 Hz. During the CNC manufacturing process, rabbets and dadoes are cut into the back panel for precise panel alignment. A unique two-piece brace adds superior rigidity without affecting the subwoofer's performance. Both side panels feature 3/4" rabbeted extensions with recesses to perfectly install the first piece of the two-part, double thick baffle. The end result is a resonance-free, sealed subwoofer cabinet that is purpose-built to extract the best performance from Dayton Audio's 12" Ultimax subwoofer. All that's left to do is finish it to match your décor or paint it to stand out.


About the Subwoofer

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. A Ultimax subwoofer tests 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. Over 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 a "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.
