Knock-Down MDF 3 ft³ Subwoofer Cabinet for Dayton Audio 15" Ultimax SubwooferEven the easiest do-it-yourself subwoofer can turn into an arduous project; from uneven cuts, to measuring mistakes. CNC knock-down cabinets make it easy for the beginner to end up with amazing finished results without all of the time and effort necessary to perfect your woodworking skills. This cabinet is designed for speaker builders and designers who don't have access to expensive tools or a woodshop.
This particular cabinet is designed specifically for the Dayton Audio 15" Ultimax subwoofer, but works for any subwoofer with an overall diameter of 15-3/8" or less, and a cutout requirement of 14" or less. For optimum performance with the Ultimax 15" subwoofer, add three pounds of Acousta-Stuf polyfill for a Qtc of 0.707 and an f3 of 35 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. Plate amplifier installation is made easy by following the scribed interior guide with a jig saw and by modifying one of the braces.
The end result is a resonance-free, sealed subwoofer cabinet that is purpose-built to extract the best performance from Dayton Audio's 15" Ultimax subwoofer. 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!"
