Denovo 18" Reference DIY Cabinet Flatpack
This particular cabinet is designed specifically for the Dayton Audio 18" Reference Series High Output subwoofer and the Dayton Audio UM18-22 subwoofer but works for any subwoofer with an overall diameter of 457 mm or less, and a cutout requirement of 407 mm or less. The sealed enclosure design creates a subwoofer system with a Qtc of 0.644 and an f3 of 40 Hz when used with the Dayton Audio RSS460HO-4 and minimal fill.
During the CNC manufacturing process, rabbets dadoes are cut into the back panel for precise panel alignment. A unique three-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 18" High Output Reference Series 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!"
