Denovo Audio 8" Ultimax Subwoofer and Cabinet Bundle
About the Cabinet
This particular cabinet is designed specifically for the Dayton Audio 8" Ultimax subwoofer, but works for any subwoofer with an overall diameter of 8-1/4" or less, and a cutout requirement of 7-1/2" or less. When used together with minimal fill, the box and subwoofer combine for a Qtc of 0.68 and an f3 of 45 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 rabbeted 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 8" Ultimax subwoofer without taking up much floor space. All that's left to do is finish it to match your décor or paint it to stand out. When your friends ask about it, you get the pleasure of saying, "I built it myself!"

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. An Ultimax subwoofer tests the strength of your foundation with fast, articulate, gut-wrenching bass.
Over 1-1/4" of travel (16 mm 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.
